Dry rotted tires

I have an 2004 class C on a Ford chassis. It came with Michelon LTX
tires. The tires seem to be cracking. I know that sun damage will cause
this, but 2 years seems a little early. Also, since both sides are
doing this and only one side faces the sun, is there other causes?

What can I expect if I ask for replacements. These tires only have 13K
miles.

TIA

I would suspect Michelin will pro-rate the tires and help you out somewhat.
Don't ask though...stand your ground.

Hi,
The tires are cracking because of non use.  When you run a tire oils in
the tire compound get forced throughout the tire and to the outside.
When it sits the oils can't migrate throughout the tire so it cracks and
dry rots.  Sitting is not good for the tires or the RV.

Michelin may prorate the tires since they are only 2 years old.  Or
they may not since it's not their fault the tires are not being used.
Give em a call and see what they say.  You should drive the RV at least
every month for 30 - 50 miles if you are not already doing that.  Helps
the tires and the rest of the mechanical drive train.

Take care and Happy Campin...

While I agree in general with what you said, I'm not so sure that's the
problem in this case. I'm comparing this to another 2 year old vehicle that
I know of with very close to the same milage on it. Different brand of tires
I'm sure, but no cracking on them. It does get driven almost daily though.

Update:

The local Michelon dealer is going to replace all 6 tires for $299.75.
They are suppose to get the tires in tomorrow.

I'll keep you posted if it happens.

WOW!  Way to go.  It's not so often we hear of such a good result to a
problem with tires.

You getting them replaced is fine, but still does not answer
why it happened. They will dry rot ok from none use but not
in that short time. Suggest you check the date they were
made, could be they were old when installed.

Hi Bill,
They will crack in that short of a period of time if you let them sit.
Had that happen to my 2001 CR-V.  It was only used as a toad and parked
the rest of the time for the first 3 years we owned it.  So that means
it was parked 5 to 7 months every year. All four tires developed
hairline cracks within 2 to 3 years.   I replaced all four tires last
year, they were another brand not Michlins.  It's not really dry rot
it's the oils not being forced to the outside of the tires.  The rubber
then gets hard and cracks.

Take care and Happy Campin...

Hi Bill,
They were not Firestones or Bridgestones.  They were BFGoodrich and
were replace with Firestones.  But I also keep enough air pressure in
them to not have problems :)

I have followed this thread for some time and have one question. Did the
Michelin LTXs have raised white letters on them? If so, then the problem
probably was not dry rot or weather checking. Michelin had a problem for a
time with their tires with the raised white letters. They used two different
rubber compounds, one in the black sidewalls and another for the white
letters. The two compounds had different rates of exansion, contraction, and
flexibility. Results -  the white letters caused cracks in the sidewalls.
Michelin determined that these cracks or splits did not compromise the
integrity of the tires but rather were a cosmetic problem only. However, at
my tire shop we continued to honor the warranty and replaced the tires. Just
a thought.

Last update hopefully.
<begin rant>
I dropped the MH off. When I dropped it off I asked the counter guy if
they knew how to get the wheel covers off and if they needed the tool
that came with the MH. He said they knew how and that they had the
tool.

So, my wife and I went shopping.  While returning I noticed it was
parked in a different spot. Hooray.....It's done!

My wife dropped me off and headed home. I went over to look at it
before I entered the business. I noticed that the right side dual had
both valve cores coming out the same hole. I am under the impression
that they should be 180 degrees apart. No big deal. I'll just have them
turn the outer rim 180.

After approaching the counter, the "counter man" advised me that the
"tire guy" lost one of the inside dual extenders and one of the lugs
that hold the wheel cover on. I am thinking "oh sh.t, how does a person
loose more than one item in a shop such as this. It is a "TIRE" shop.
They sell tires and wheels. They don't do anything else. But again I
thought it is no big deal because I am sure they have the parts they
lost. I was wrong. The "counter guy" said it may take a few days and to
bring it back. I advised him that I live 25 miles away and get 9-10
miles per gallon and he can do the math to see how much it will cost me
to bring it back. He seemed surprised so I gave him a quick math
lesson. I told him it is 50 miles round trip and I'll use 5 gallons of
gas. "IF" I can find gas for only $2.50 a gallon (which I can't because
gas is $2.89) it will cost me at least $12.50. Now he was more
surprised. I also told him that there was a RV center 2 blocks away and
they would have the extenders and wheel cover lugs. The light finally
turned on over his head and he called them to see if they had the
parts. They said they did so he sent the "parts runner guy" to get
them. In the mean time he found the wheel cover lug. Cool!

After about and hour the "parts runner guy" returned and the "tire guy"
began work. I asked the "counter guy" I was going to watch, he said it
would be ok.

Tire Guy get it jacked up and gets out his impact wrench and starts to
remove the wheel cover. After he takes off the first wheel cover lug I
notice the chrome/stainless cover of the lug is cracked. I told him he
cracked the cover and he denied it, he said it was already cracked and
that they had to use the impact wrench to get it off. I told him that
was bullshit because I had taken the covers off about 2 weeks earlier
it clean them and they couldn't be on that tight using the proper tool
that came with the MH. I went to the compartment where I keep the tool
and got it out for him. After he used it, he agreed that using the
proper tool wouldn't have cracked the outer casing. OK, no big deal.
I'll replace them later. I did advise the counter guy that I may bring
him a bill if they are expensive. He agreed.

Finally, I am out of there. After parking it in the driveway I also
noticed that the front wheel cover was crooked. I got out the tool and
removed the cover to install it correctly. I noticed they had bent the
cover while installing them with the impact wrench ( I presume). I was
able to pound it out easily with a mallet. There is still a VERY small
dent tho. Also, they didn't install either of the front extenders.
Damn!

 This was the worse cluster f**k I have seen in many years. They
obviously hire inexperienced help (kids) and don't train them. I don't
blame the kids, they just do what they are told. I blame the management
for not training/supervising them. I also learned that just because it
is a "Tire Store", it doesn't mean they know everything.

<end of rant>

To answer Dave: No, they weren't white letter tires.

Damn Hank,
Where did you take your rig? Let us all know so we can avoid them. Didn't
really think that it was the "raised white letter" problem returned but it
was a possibility. Michelin's quality is (at least used to be) very good. As
one other poster suggested, perhaps they were already old when they were
installed. Too bad you had such an experience, makes the tire shops that are
trying to do a good job look bad. Honestly, there are some good shops out
there....

Hi Dave,

   It was one of the biggest tire stores in Columbus, Ohio. It was
Discount Tires.

   I know there are good tire stores. One is right down the road from
me. I went there first but they aren't a Michelon dealer. Oh well.

    I agree that they may have been sitting for while before I bought
this MH new in 04. But, why aren't any of my other tires cracking? I
have a trailer that I bought in 2000 and it sits more than the MH and
also in the same location in regards to sunlight. I am soooooo
confused. :-)

I've never dealt with them, they appear to be relatively new to the area
(and are on the other side of town from me anyway). I've used NTB off of
Sawmill or Wilson Road,  and have always had good results from them. They
installed Michelins on my Class B, but because they are truck tires, I had
to order them in advance and wait a couple days. They also had to special
order the stems at the same time.

That's been my experience with tire dealers. Unless you go somewhere that's
specifically set up to handle trucks, you have to keep an eye on what they
are doing. I do specify that they tighten the lugs with a torque wrench,
there was that time that I broke a wrench trying to change a flat on the car
with a thunderstorm approaching. Those guys in those car tire shops also
don't know about inflation tables for trucks, along with the fact that
there's greatly higher pressures required in some truck tires.

Actually, the best shop is the one that will let you stand
behind the mechanic and oversee him doing a job that he rarely
if ever does.  The shop that I go to is good, but I think mine
is the only RV that they service.  Everytime I am in there,
there is another Corvette getting tires.  Anyway, last time they
did work for me on the RV, I took it over in the late afternoon
and they began work on it in the morning just as I got there to
oversee.  I am glad I was there.  I had to help the mechanic
several times including no to the speed wrench for the nuts for
the wheel covers, and help with the extensions.
