Hello folks--with good news---
The "Michelin Man" was here at the dealership last Wednesday, a week ago. He was going to look at my tire and he didn't get around to it
I've been waiting for a call from the dealer in Gulfport for over a week (we are here for the winter, only about 5 miles from the dealer). Today I went by the dealer and came out of the store with a great big smile on my face. Chris, the store manager, said Michelin must have other things on their mind right now. He said we're going to replace your tire and I'll deal with Michelin later. He said Michelin was going to pay for the service call (although they didn't know about that yet). They came out to the RV park this afternoon and mounted a new tire on my old spare (which I paid for, at the price I paid two years ago) and in twenty minutes I was done. Both new tires have a mid October, '09 born date on them.
Hey, that's above great service--it's fantastic! I'm tickled to death. I'm going to run all my tires at 105-110psi cold from now on. 110psi is the max cold pressure allowed for this tire (235/80 22.5 XRV). I was running at 90 to 95psi. We'll see what happens at that pressure.
I read a thread here on iRV2 recently and, of course, I can't locate it right now for a quote. The writer said something like this--
" a long time ago I had a blow out in Tennessee on the interstate. An old crusty tire guy came out and said your probably running Michelins, your valve extender is riveted to the wheel cover and it's the right rear, inside dual".
"BINGO" that sounds like me. Both my blowouts this year were on the RR inner location.Then he told the chap to inflate the tires to the max allowable because you never know exactly what your weight is. The writer said he has done exactly that for years now and has had no more problems. Now that I think about it, with a rig my size,37' 11" long, a long rear overhang, roads with crowns on them, almost always to the right side , I can see why extra stress is placed on the RR inner dual. It probably works harder than the other 5 tires do. I think rigs with tag axles don't experience this type of stress on RR inner duals. Comments from readers, and engineers, on this theory (and its only a theory for me) please.
I will now, after having two blowouts this year on the right rear inner dual,
ascribe to that theory.
For those interested in the dealership I was working with- here it is:
TCI Tire Centers
9259 Canal Road
Gulfport, Ms 39503
The manager is Chris
Get off of I-10 at the Canal Road Mississippi exit, go South about .3 of a mile and they are on the left (East) side, just past the Shell station. Flying J is on the right just as you get off the interstate. Stop and get some fuel at Flying J, ease on down about .1 of a mile south and pull into their large facility with plenty of room to drive around. Be nice and polite and be patient-- Good things can happen
. Tell Chris I said hello- He is from eastern NC, close to where our home is.
Cheers and happy traveling to all our iRV2 friends-- Happy Thanksgiving and a great Christmas and New Year!
