Car Forum / Driving, Maintenance, Tuning / RVs / July 2006Specific Tire Pressure Question
I have a '99 K1500 GMC Suburban. It came with p-metric tires (GAG!!!). I finally replaced them with LT tires. The recommended pressure for the P245/75/16 was 35 psi. There was no recommendation for any other tire. Anybody with a similar 'Burb whcih came factory with LT tires have a different recommended pressure for the LT's? Mike D. I see where "Mike Dobony" <sword@notasarian-host.net> contributed: >I have a '99 K1500 GMC Suburban. It came with p-metric tires (GAG!!!). I >finally replaced them with LT tires.

If you really want to know the correct pressure, forget the door label. Instead, weigh the 'Burb and consult the inflation chart for whatever tire you're using now. That will give you the best combination of ride, handling, tire life, traction, etc. Will Sill The Curmudgeon of Sill Hill > I have a '99 K1500 GMC Suburban. It came with p-metric tires > (GAG!!!).

The short answer - no one can tell you what pressure you need to run with the information you provided, because from what you posted, it appears you are using it for something besides a passenger car. Now, what you need to know: Until you know what rims are on your GMC, you don't want to go higher than 50 psi. Your GMC dealer parts department can most likely give you the psi rating on the rims. If they are not rated for 80 psi (max. psi of the new tires you bought) you need to get the correct rims. Once you have the correct rims, if you tow a trailer or haul some other load other than passengers, hook/load what you normally drive down the road and head to a public scale and get it weighed. With load charts for the tires you bought, you will then know how much pressure you need. Google for the load charts for your tires. Tom J > you need. Google for the load charts for your tires. Chances are it will be difficult or impossible to find load charts for the specific model of tires. However, if one uses google groups and searches for past discussions on tire pressures, general pressure charts for specific tire manufacturers and for a tire manufacturer association can be found, which will provide some clues. > > [quoted text clipped - 8 lines] > > With your situation I would get the higher pressure rims and load range D tires and weigh the rig and go by the pressure recommendation on the tire.

I would not wast time or money on these. Some good LT oe C range tires will handle on the weight that the axles and spring will handle safely and be more stabily towing than with current P metric ones at 35 PSI. ----------------- The SnoMan www.thesnoman.com >>>>you need.

Are there many tires (of any type) rated for a maximum less than 44 psi? The last 5 different models of P metrics I've had on one sedan and the OEM P-metrics on two pickups were rated for 44 psi. I can't remember more before that. > > Tire manufacturers have been building SUV type tires with a maximum > > pressure of 44 psi. They are still P metric but are stiffer tires.

If I bought LT tires for my truck, which I will do when it needs tires, I'll follow the same charts I do now which, for me, is pump 'em up till they feel right. I ran our '96 Sierra P series (max 35 psi) at 45 and 50 psi while towing. Never had a tire failure and did enjoy comfortable towing.

You might want to double-check the max pressure: if they used the same 17" tires/rims as the other 2003 models [Wrangler GSAs] then they have a max pressure of 65#.

If I were going to pull a 5th wheel, I'd want LT tires for sure. Would still like them but not till these are worn enough to justify spending the money. I don't rotate my tires, usually. I may rotate left front to right rear and vice versa. Have 25,000 miles on it and the tires are making a bit of noise. I won't let the dealer or anyone else do it though.

Good grief! The Suburban came from the factory with wheel rims that are designed to support the weight that the whole vehicle is designed to carry. Higher capacity rims or tires won't change what the vehicle is designed to handle. SignatureJon JPinOH > Good grief!

The OP said he has already bought LT tires and had them installed on the OEM rims that are most likely only rated at 50 psi and then wants someone here to tell him what tire pressure he should use.

The reason no one answered your question is for the reasons already stated, that is, if you didn't change the rims also, it will be unsafe to inflate them to the recommended pressure. DID YOU GET HEAVER RIMS? DID YOU WEIGH THE SUBURBAN? What did the rear weigh and what did the front weigh? Answer those questions, and if you got the heavy duty rims, you can get an answer on how much air you need in those tires. Tom J >>> That is not the point!!

When I picked out this truck there was an almost identical Suburban that had the SAME rims and FACTORY LT tires.

So, in keeping with your input, I'd say there was no way anyone can advise him until they find out what the standard rims are rated for. Besides, if he uses a weigh-in of his rear axle for a basis, the only time he'd need more than tire pressures listed on the doorpost, would be if he was going to haul an illegal load. In that case no one should give any advice at all.

Trucks/truck-based-SUVs haven't changed substantially in the few years that yours has been aging. > Olnly you tow are stupid (deliberately ignorant) about needing Oh, the irony. > different tire pressures when empty and carrying a full load. THAT is > deadly advice!!!!!!!!!!!!!!!!!! UNDERINFLATION > KILLS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Indeed, I've seen/heard of more than my share of tire related accidents. I believe the difficulty here may be in the definition of "underinflation". Tires operate by using air to hold up a load. Depending on how much load the tire is carrying, it requires a different amount of air to carry said load without deforming so much that it overheats and breaks. It is safe (and, depending on the context, absolutely necessary at times) to use different pressures at different loads. In the context of a Suburban hauling nothing vs. hauling a few kids to soccer practice, well, the empty Suburban can safely have the same pressure as the soccer-kid-full one. In fact, in a 1500, there's probably not enough difference between empty and legally full to need to let out air when empty. OTOH, in a heavier truck, a tire that has a good contact patch and flexibility when the truck is loaded may need some air let out if you don't want a tiny contact patch and basketball-like bouncing when empty. For example, a Sierra 3500 with single rears has a curb weight of 5687 lbs and a GVWR of 9900 lbs, leaving a whopping 4213 pound payload capacity -- most of which would be carried by the rear wheels. It is rated to carry almost as much as it's curb weight, and I'll bet the rear tires end up with double the weight when loaded vs. unloaded. Do you suggest that a tire should have the same pressure when carrying double the load? Some vague math to help demonstrate: Curb weight divided evenly by 4: 1421.75 Payload divided evenly by 4: 1053.25 ...and that's not considering that the rear end of the empty truck is probably lighter than the front end, and that most of the load goes on the rear end. In practice, I find that for _me_, tires inflated beyond the weight chart (but not beyond their maximum pressure) perform well for me. I don't measure their temperature in 176 different places, I just pay attention to ride/handling and wear. >>I don't measure their temperature in 176 different places, I just pay >>attention to ride/handling and wear.<< If you are going to be real fussy about tire pressures empty/with load, the way to do it is with a temp gauge that will read tire temps. That way you can tell 10 miles down the road not 2000 miles later. Take tire temps. at both edges and the middle. If the middle is hotter, you have too much air in the tire. If the edges are hotter, you have too little air in the tire. It's done with race cars all the time.

Makes sense, although I don't know if it is quite as applicable to narrow, tall truck tires with hard compounds and carcasses designed to last 50,000 miles under heavy loading as it is to very wide, slick, low profile race car tires with very soft compounds intended to last a hundred miles and abused much worse. Anyway, once you get a feel for what's a good pressure for your rig, you know how to adjust without having to wait another 2000 miles. > > >>I don't measure their temperature in 176 different places, I just pay > > >>attention to ride/handling and wear.<< [quoted text clipped - 15 lines] > Anyway, once you get a feel for what's a good pressure for your rig, > you know how to adjust without having to wait another 2000 miles.

I believe the difficulty here may be in the definition of > "underinflation". Under inflation in the context of MY truck and it's usage: original tires were just barely rated for an empty truck (full tank of gas, 43 gallons) plus driver when fully inflated to 35 PSI. Zero room for loading it down with toolboxes, bags of concrete, landscaping blocks, lumber, drywall, furnace, etc., driving at highway speeds up to 65 for 40 miles or so each way. Not safe to inflate above the recommended 35 psi (capacity of the tires) to accomadate the extra weight and overloading the tires by several hundred pounds. > Tires operate by using air to hold up a load. Depending on how much > load the tire is carrying, it requires a different amount of air to [quoted text clipped - 7 lines] > probably not enough difference between empty and legally full to need > to let out air when empty. Poor context. 9 passenger full of adults is 8 x 200 = 1600 lbs extra. This being done on a regular basis for minimum of 1 hour on the interstates (65-70mph). This is almost all in excess of the carrying capacity of the origional tires. > OTOH, in a heavier truck, a tire that has a good contact patch and > flexibility when the truck is loaded may need some air let out if you [quoted text clipped - 5 lines] > the rear tires end up with double the weight when loaded vs. unloaded. > Do you ? I totally agree! Problem is reversed with original tires. There was NO, ZERO, NADA capacity to add pressure to accomadate the extra pressure needed to carry the additional load and even empty the weight of the vehicle was at best at the maximum capacity of the tires! The new tires can carry a combined weight of 8800 lbs. The rims are rated at 8000 combined weight. The truck is rated at 7300 lbs. Therefore I will NEVER have to inflate to the maximum capacity of the tires (50 psi). The original tires had a total capacity of right around 5000 pounds and the truck weighed in at just over that when we went to the scrap yard, about 5500 as I recall. Suggesting that a tire should have the same pressure when carrying double the load is a gross invention of OTHERS here, NOT me. I simply do not believe the manufacturer recommended pressure for P-metrics is sufficient for a truck with a GVWR approximately 1 ton greater than the tire's capacity! I also believe that the recommendation for LT tires will be higher than the P-metrics. In addition, I believe ti to be gross negligence for the manufacturer to put tires on a truck which can barely handle an empty truck. Stupid people are trying to inflict upon me different intentions. They refuse to read what I said. > Some vague math to help demonstrate: > Curb weight divided evenly by 4: 1421.75 [quoted text clipped - 7 lines] > don't measure their temperature in 176 different places, I just pay > attention to ride/handling and wear. I am only measureing in 3 places. Your exageration is what I consider stupid because you are, in total ignorance and pre-judging, inventing a position for me that I NEVER took.

I'm quite sure that it's entirely illegal for a vehicle manufacturer to ship vehicles with tires not rated to carry the GVWR of the vehicle. It's certainly extremely improbable even if not illegal -- imagine the fallout from the string of tire failure disasters! When loading with toolboxen, cocnrete, blocks, lumber, drywall, furnace, etc, keep in mind the GVWR of your vehicle. It should not be exceeded. If you're exceeding it so much that load range C tires (the heaviest factory option) are overloaded, you might need a heavier vehicle. > > In the context of a Suburban hauling nothing vs. hauling a few kids to > > soccer practice, well, the empty Suburban can safely have the same [quoted text clipped - 3 lines] > > Poor context. 9 passenger full of adults is 8 x 200 = 1600 lbs extra. This Who's putting words in whose mouth? I wrote "a few kids" and you wrote "9 adults". 1600 pounds is probably overloading your vehicle. 1600 is about the payload capacity of my 2002 Sierra, which does not have seats, walls, ceiling, and glass on the rear 7 feet of the vehicle, and which is newer after (your words) a "MAJOR model change ifor 2000". Okay, so 1600 pounds. I'd guess (this is just a _guess_) you're looking at about 40% of that additonal weight on the front and 60% on the rear. That's about 640 pounds additional load front, 960 additional in rear. 320 pounds difference per tire on the front means, to me, you'll definitely not need to bother changing the pressure per load. I suspect that the 480 pounds each rear would also be okay, but you would only be able to tell from experience. Either way, the pressure to choose if you don't want to change it per load is the higher pressure, the one required to carry the maximum load. > the maximum capacity of the tires (50 psi). The original tires had a total > capacity of right around 5000 pounds and the truck weighed in at just over > that when we went to the scrap yard, about 5500 as I recall. I really have a hard time believing this. Perhaps the tires that came on it were not OE from the factory, but were swapped on the lot by the dealer for another customer, with no regard for the buyer of your vehicle. No way would GM be dumb enough to ship a vehicle with tires whose capacity is less than it's curb weight. > Suggesting that a tire should have the same pressure when carrying double > the load is a gross invention of OTHERS here, NOT me. I simply do not I must have misread you when you wrote this: > new truck. Olnly you tow are stupid (deliberately ignorant) about needing > different tire pressures when empty and carrying a full load. THAT is You must have meant that different pressures _are_ necessary, and that some two people suggested that they aren't. Anyway, my example of a brand new Sierra 3500 was an exaggeration for demonstrative purposes. > believe the manufacturer recommended pressure for P-metrics is sufficient > for a truck with a GVWR approximately 1 ton greater than the tire's It's easy enough to find the appropriate pressure, at least for you to start at and fine-tune on your own. See http://www.michelinrvtires.com or the website of the manufacturer of the LT tires you bought. The load-inflation charts seem to standard across manufacturers and load ranges anyway, possibly made by the Tire & Rim Association. > capacity! I also believe that the recommendation for LT tires will be > higher than the P-metrics. According to Goodyear's chart at http://www.goodyear.com/truck/pdf/databook/loadInflation.pdf your OE P245/75R16 tires, when de-rated by 10% for using P-metric tires on a truck, are good for 1860 pounds each at 35 psi. That's 7,440 pounds. You said: > The truck is rated at 7300 lbs. Anyway, you're correct that LT tires need more pressure than P-metrics. The same chart says of LT245/75R16 tires that 40 psi is required to carry 1845 pounds. > In addition, I believe ti to be gross negligence > for the manufacturer to put tires on a truck which can barely handle an > empty truck. As researched above, the tires are most probably okay. I guess it's possible (though unlikely) for another brand tire to be rated so differently from the Goodyears. You said: > The original tires had a total capacity of right around 5000 pounds If that was true, the tires in question would have to be rated for 600 pounds difference each compared to Goodyear tires, 1200 lbs vs. 1860 lbs. >When loading with toolboxen, LOL.

You are correct. By the charts I should have had no problems with capacities. All you have to do is tell that to the tires. I am still interested in finding out what the factory recommended for factory LT tires. Why is that so hard a question to be answered without such condemnation for unsafe practices which I never had any intention of doing anyway? Why do people have to invent arguments over imaginary actions and conduct? Regardless of what the charts say and what the tires actually need, I still want to find out if there is a difference in factory recommendations between the P-metric and the LT tires. I am also interested in why they couldn't list the LT recommendations along with the P-metric. Most serious users of trucks go to LT tires, at least those that I know.

Sorry, that was a bit of a tangential theory, not a question of a concern with your existing tires. My point was, while we're on the subject of heavy loading, be sure you're not overloading your vehicle. > The rating on the tires said just over 1,000 pounds.

I merely said that if it looks like a duck, walks like a duck, smells like a duck, and quacks like a duck, it's probably at least something vaguely avian. If you went to rec.bicycles.misc and asked if you should wear a helmet, you would get the same thing, only _much_ worse. It doesn't matter if you asked seriously with the intention of becoming ifnormed. Somebody who asks about helmet wearing there is going to catch a lot of schitt, and if he then proceeds to offend the folks who are trying to help, he's going to catch even more. > chain reaction of lies and false condemnation!

I gotta ask: Why did you go to a community of anonymous amateur advice givers for an authoritative answer that would have been easy to get from the authority? You want to know what GM recommends; why don't you ask GM what they recommend? If you ask here, you're going to find out what people here recommend. I wouldn't ask rec.bicycles.misc what they think my local bike shop will recommend; I'd ask my local bike shop. > > > Most serious users of trucks go to LT tires, at least those that I know. > > > > GM's position will probably be that most serious users of trucks go to > > the 2500 series. > > Depends on the definition of serious. You said "Most serious users". My guess was that GM's would interpret your language in such a way that they'd say "most serious users" ought to use a heavier truck.

He was trying to get Seven of Nine to taste it, but she was reluctant. Finally she gave in, and it turned out it wasn't bad. She said, and I quote (this is almost verbatim), "Hmmm. It has a taste vaguely reminiscent of a certain species of twentieth-century domesticated Earthian fowl." Nobody acknowledged the line, and the dialogue went on from there.

That should tell you something Mike. 250/2500 trucks may come with LT tires as standard equipment so, the door post info would not be for P series but instead be for LT series. To the best of my knowledge, there were no '99 150/1500 trucks that came standard with LT tires. This is why I say your question is unanswerable. Hugh > snipped > > I asked a simple question. Why do I get answers from people who are totally [quoted text clipped - 10 lines] > This is why I say your question is unanswerable. > Hugh Your best knowledge is WRONG! As I stated numeerous times, I had a choice between two exxentially identical 1500 series Suburbans. One had barn doors and factory LT tires. The one I bought had the tailgate and p-metric tires. I didn't like the blind spot of the barn doors and changing from P-metric to LT tires is simple. Then there is teh infor I just got from a different NG that also says you are wrong: > 42psi all around is the factory recommendation on my factory michellin LT > 1500 4x4. The question is answerable, but only from someone who has, who knows someone who has, or who had said truck. I did not ask what pressure to put in the tires, nor did I ask how to determine the best pressure to use. I asked what the manufacturer claimed on the doorjam. A very specific and simple question and an abundance of ignorant (they lacked the information requested and lacked factual information on what was available at the time) and totally inappropriate responses.

It's a hard question because it is a DUMB question, especially from someone who thinks he knows more about the issue that the poeple trying to help him. It's a Dumb Question for several reasons, not the least of which is that the factory guys do NOT know whether you load lightly or heavily.

That was NOT the question!!!!!!!!!!!!!!! Why do you have to be so stupid in giving an answer to a question not asked?????????? The door tag gives maximum weights, not actual curb weights.

If you don't you have no reason to respond, especially with false allegations of overinflating the tires beyond what the rims are rated for, etc. Why do you insist on giving an anwer for a question not asked??????????????? > snip<> >I am still interested in finding out what the factory recommended > for [quoted text clipped - 29 lines] > etc. Why do you insist on giving an anwer for a question not > asked??????????????? P.S. all the non-answers/verbal assaults are entirely appropriate when directed toward the installer who insisted on inflating to 80 PSI. I had to fight to get him to keep it at 50!!!!!!!!!! As soon as I got across the street to Walmart I dropped the pressure to 37 PSI, 2 psi above the recommendation on the door jam.

The tires don't care what vehicle they are on, and the charts for the tires are for all vehicles on which the tires can be mounted. If you just gotta have the door tag figures, then go find a vehicle that has one and take a peek.

Trouble is, he isn't going to find an answer because 150/1500 series trucks don't come standard with LT tires. All the advice to weigh and use chart recommendations are being tossed aside while he fights windmills. Hugh snipped > Another stupid person looking at irrelevent info. It is NOT a pickup, nor a > new truck. Olnly you tow are stupid (deliberately ignorant) about needing > different tire pressures when empty and carrying a full load. THAT is > deadly advice!!!!!!!!!!!!!!!!!! UNDERINFLATION > KILLS! Whoa there Mike. I was wrong about there being no LT option for 150/1500 vehicles and already admit that. As has already been pointed out, the 150/1500 vehicles are offered with LT tires as an option and different rims aren't in that option. As standard rims apparently rated for 50 psi or so and load range C (in LT series tires) are rated at maximum load at 50 psi, as long as someone doesn't put load range D or E on a 150/1500 they are okay. Now just to set the "record" straight Mike, where do you see either me or Tom recommending anything like you claim we did? Everyone is sorta saying the same thing, inflate for the load carried. If someone bought load range E tires and tried to run 80 psi in them, they'd be in a lotta hurt if the wheel burst. Just for grins now, what load range LT tires did you have put on? If they are D or E range, the max pressure you would need is 50 psi. The tire charts that have been posted already have all the info you need. The door post info for a Sub with the LT's as an option doesn't mean anything. For grins, I just checked my '03 Dodge Ram door info. I know, I know, it isn't an '01 Sub but that doesn't mean anything for this discussion. My truck came with optional P265/70r/17 tires yet the door post info refers to the standard tire P245/70r/17. So, unless GM does it differently that will be the case for your questions. Frankly, I don't see why you're getting so upset. Hugh > different rims aren't in that option. As standard rims apparently > rated for 50 psi or so and load range C (in LT series tires) are rated > at maximum load at 50 psi, as long as someone doesn't put load range D > or E on a 150/1500 they are okay. He said his rims are rated for 55.

If someone bought > load range E tires and tried to run 80 psi in them, they'd be in a > lotta hurt if the wheel burst. Well, everyone didn't say exactly the same thing -- I did, at one point, suggest it's okay to inflate beyond the wheel's rating, but I retracted it when I learned that the consequences far exceeded my guess of the valve stem blowing out. > snipped > > Another stupid person looking at irrelevent info.

Congratulations Mike. It appears that you have stumped our panel of experts here on ALT-RV. Try this link. https://www.mygmlink.com/main/US/en/gm/home?cmp=gmcomhp Jim snipped > Really? When did someone with a '95-99 4wd 1/2 ton Suburban which came from > the factory with LT tires tell me what the door tag recommended for > pressure? I missed the answer in all the stupid threats about blowing up > the rims for overloading them because they know better than the manufacturer > what the rims are rated for? You're not going to get an answer to that question because the door post info will be for the STANDARD tire offered, not for any optional tire. I had a '96 Sierra 1500 pickup and it came with P series tires which called for a maximum psi of 35. IIRC, they were rated for somewhere between 1,600 and 1,800 lbs each. I mention this because my tires were probably similar to what you had on your Suburban. Hugh > In case you're still here Tom, I checked both GMC and Dodge sites for > info on availability of LT tires on 1500 pickups and neither offers > them. So, in keeping with your input, I'd say there was no way anyone You missed a spot. Warning: The following link is a "Print All" link. You will get your print dialog box, or maybe it will start your printer. However, it does show all optional tires. http://www.gmc.com/sierra/specsPrintAll.jsp?vehicle=1500 In that page, you'll find: : LT245/70R17, all-terrain, blackwall, 6 ply-load range C (Requires 4WD with Handeling/trailering Suspension Package) IIRC, load range C is 50 psi. The mispelled Handling/Trailering Suspension Package does not include any particular wheel. With that clue in hand, I'd guess that those wheels all are rated 50psi, like the 16" wheels on my 2002 Sierra 1500 (which have a label you can see if you remove the tire). >>In case you're still here Tom, I checked both GMC and Dodge sites for >>info on availability of LT tires on 1500 pickups and neither offers [quoted text clipped - 16 lines] > 16" wheels on my 2002 Sierra 1500 (which have a label you can see if > you remove the tire). Okay, I see it. Looks like you are correct. As long as someone doesn't buy any higher than the C load rating they won't be in trouble. D range would be a possible troublemaker and anything higher would be a definite no-no. Like Tom points out a ruptured wheel will getcha in a whale of tub of poop. I see it as the C range would be a direct replacement of the OEM P series tires. I did find one site that had load rating information on P series; <http://www.1010tires.com/tech.asp?type=tires#sizing> This chart should apply to all the P series tires used on light trucks and suv's. Hugh > definite no-no. Like Tom points out a ruptured wheel will getcha in a > whale of tub of poop. You mean, like http://www.tubgirl.com ? Warning: Link not safe for work, home, people with pacemakers, people without pacemakers, or anybody who is easily disturbed or grossed out. Imagine an actual photo that is related to the statement "whale of tub of poop" if you're considering actually looking at that link. It's worse. > >>In case you're still here Tom, I checked both GMC and Dodge sites for > >>info on availability of LT tires on 1500 pickups and neither offers [quoted text clipped - 22 lines] > definite no-no. Like Tom points out a ruptured wheel will getcha in a > whale of tub of poop. Prov 17:28 28 Even a fool is counted wise when he holds his peace; When he shuts his lips, he is considered perceptive. NKJV Prov 15:2 2 The tongue of the wise uses knowledge rightly, But the mouth of fools pours forth foolishness. NKJV So you can't put E rated tires on and only inflate to what is necessary to carry the load? My C rated tires at full inflation (50 psi) are above the maximum GVW of the truck. Therefore, unless you are as stupid as the tire installer who insisted that despite the tire manufacturer's tire capacity and inflation recommendations ( vehicle manufacturer inflation chart) I need to inflate them to 80 psi, I am perfectly safe installing E rated tires and keep the pressure below 50 psi.

In '99 Suburbans had LT tires available as a FACTORY OPTION!!!!!!!! I had SEVERAL to choose from and about half had LT tires FROM THE FACTORY. I turned them down because the only other SUBURBAN with the options I needed/wanted had the barn door and I didn't like the lack of visability it offered. It HAD FACTORY LT TIRES OPTION WITH THE SAME RIMS I HAVE NOW!!!!!!!!!!!!!! > SUBURBAN, NOT PICKUP!!!!!!!!!!!!!!!!!!!!

I wonder if the door pillar tag on one of those with LT tires would show the differences, if any? SignatureJon JPinOH > > SUBURBAN, NOT PICKUP!!!!!!!!!!!!!!!!!!!!

In case you haven't figured this out already, THAT is what I am interested in! I started having trouble with the tires 2 years ago, but my stingy wife didn't want me to buy new tires. It took a black baseball on the side of a tire to finally get new tires. I have had to put up wiht shaking and pulling for 2 years!!!!! I don't know if it is because of simple age (only 35,000 miles on the original tires), insufficient capacity (the tires were also rated at only 35 PSI, despite what others here have), or junk tires. Manufacturer recommendations are not gospel. They are a starting point, adjusted according to wear. I just got back from Harbor Freight and they had a small pocket non-contact thermometer and the it shows the back tires of my car are very close to proper pressure (107.2, 106.8, 107.1 and 107.3, 106.9, 107.2) and the front are under inflated (110.7, 106.4, 110.4 and 112.5, 106.8, 110.3). It also looks like I need a front end alignment again. Mike D. >I started having trouble with the tires 2 years ago, but my stingy wife >didn't want me to buy new tires. Wow. I can't even imagine. My wife and I are both very "thrifty" (but generous, not stingy). But when it comes to tires -- or anything else related to safety or health -- we agree: Buy at the first sign of need (or before), and buy high quality. Our lives are too important to do it any other way.< |
