Car Forum / Chevrolet / Chevrolet Corvette / May 2004Tire Pressure for Goodyear 225/70/15
I'm running Goodyear GT2 225/70/15 tires on my '69 350 vette. What is the correct psi for that tire? Thanks, Charles The max tire pressure is ALWAYS indicated on the sidewall of the tire. ==================================================== >I'm running Goodyear GT2 225/70/15 tires on my '69 350 vette.

If you run it it will ride like a rock. Your owners manual should tell you and their should be a label on the drivers side door near the latching section of the door, sometimes its repeated in the engine decals on the that are usually on the drivers side. Most people I know with a 69 run 32 PSI.

I contacted a GoodYear store, and they told me that 37 psi was a good pressure to use. I contacted a Corvette shop and they told me 32 psi. So, maybe 32 to 37 psi is a good range for good ride, good handling, even tire ware, maximum tire life, and good gas mileage for 225/70/15 tires on a '69 vette.

Most people I know with a 69 run 32 PSI. I keep my 275/40/17 at 28-30 psi. Is that fine? Any better sugestions?

Might try 32 all around and see how it feels, if too stiff for you drop it back to 30 and that should work just fine. SignatureTedd Riggs Redmond, WA >I keep my 275/40/17 at 28-30 psi. Is that fine?

Some of the more ignorant tire shop employees will tell you the proper pressure is the max pressure listed... Yikes! My 78 original door sticker states: Reduced Load: 20 PSI Front and 26 PSI Rear Heavier Load: 28 PSI Front and 32 PSI Rear. That's with P255-60R-15 tires. You will rarely find any owner's manual for any GM car recommend pressures higher than 32 PSI regardless of tire size and type of car/tire. > It has been a common, but improper practice in recent years to run > higher tire pressure because of the max tire pressure listed on the [quoted text clipped - 12 lines] > pressures higher than 32 PSI regardless of tire size and type of > car/tire. For my 01 Trans Am (275/40-17's) it's 30psi cold unless you're running "for extended periods above 100 mph" in which case it's 38psi cold. That's straight from the owner's manual, with a disclaimer about legal speed limits or something. ;) Ray Charles, That is about where my tires remain, somewhere in the 32-37 range. I usually aim for about 34 when cold to allow for a little leakage. 37 psi is Ok as the handling is nice, but I find that in wet weather, they break loose to easy at 37, so I back it off. On your manual and the 24 psi....Maybe they got confused and meant 34, never heard of a tire that low !

And I see 44 psi for the maximum. But I don't know if that is really the "correct" tire pressure for my car, although it could be. And I wanted to know what people on this forum felt was the correct pressure for that tire on my car. Does anybody have any opinions?

I'd think 44 psi would be a nightmare for both ride and tire life. And of course you wouldn't want to inflate them to 44 psi cold anyway. Goodyear's website says to use whatever the car manufacturer recommends. Look in the owner's manual for your '69 and go with that. AJM '93 Ruby coupe, 6 sp. I believe you probably had 28 cold and 32 hot. This is a pretty common figure for Chevy cars back then. Many like to run about 35. A lot depends on two factors - ride comfort and wear. If the ride is too soft, ad air. Too hard, decrease air. At the same time, if wear is greater in the center, decrease air. Greater on the edges, increase air. Greater on one edge than the other, get an alignment. > > You are right. And I see 44 psi for the maximum.

But the manual assumes 4 ply tires, and not the radials I now use. Twenty four psi, in my opinion, doesn't sound right. Charles >>You are right. And I see 44 psi for the maximum.
