That's playing Russian Roulette with your tires, that's just asking for a blow out or tire failure

My point exactly, and running at the minimum allows no room for suspention loading on tight curves.

Yup, but over inflation is just a big a problem and maybe more so-causing poor handling, improper tire wear, etc.

Havent seen any posts advising to over inflate tires but you are absolutely correct.

MH is a 2006 DP MA
We have put 30,000 miles on them.
I inspect them between and before each trip.
I have the "Pressure Pro System" on all tires, and keep them inflated at the following pressures all the time: front axle: 115 psi, drive axle 85 psi, tag axle 75 psi, which were the recommended pressures by Newmar.
MH weight is around 36,000 lbs.
I believe they can safely last 10 years.
Tell me if I am wrong.
Thanks.

Mine have about the same date as yours. My mileage is about 2K less. Backing in some soft sand after driving about 250 miles and the outside rear drivers tire spun off the rim. Turned out that the layers of the sidewall separated and the air escaped into there and decreased the pressure in the tire itself and with the lower pressure I was able to lose the bead seal. All of my tires had small cracks in the sidewall but they don't look that bad. This was on the inside of the outer rear tire so you could not see it on inspection. I'm just lucky it happened when I got home and not on the interstate at 65 mph. I'm getting a whole set of non-Michelins on Tuesday.

Just to be sure are you saying the inside of the tire** itself or the inside outer wall between the inner and outer tire? **the one that went flat

edit;
Generally when the inside of any tire starts separating it's because of heat caused by being under inflated.

I've read your response several times now and I want to ask you. "Why do you have XZE's on the front tires and XZA on the back?" Please share your reasoning, I was planning on replacing all 6 of my XRS's this season, I only have 28,000 miles on 2005 tires. I'm leaning towards just replace my front tires this season (safety sake) they are all in great shape. I'd like all the information I can get to help me make this a painless ordeal.

Thanks.

If your tires are six years old and in great shape, the only reason you may want to change your ties is for peace of mind, not safety. Nothing wrong with that, but just an unnecessary expense at this time. No one can put a price on peace of mind and I personally find it very important. However, I have peace of mind in knowing that Michelin says that as long as my 7 1/2 yo tires are inspected yearly by a Michelin rep and pronounced safe, I'll keep mine for ten years or if they need to be replaced earlier.

They don't say NOT to not replace them, just that you don't have to. I'm going on 8 on mine and have them checked before my annual trip every year. So far, so good. And yes, I have XRVs.

I have my originals, 30k miles and look great. Check out the Michelin TSB. I do believe 10 years is the the very end of useful life on most rubber products.

Make that two of us FDchief my tires look great with over 30,000.

Same here. 30,000 5 years on 315/80R/22.5 Pilote XZA1

Since I do not have access to scales, I use the Manufacturer's weight numbers, keep the water tank at minimal as well as all other tanks empty - for travel - except the fuel () and this gives me 95 PSI all around on my XRVs 305-70 - DSDP 2006 and the tires are in great shape and keep their AIR

Thank you Gary and thanks to all those who made appropriate suggestions.
It helped a lot.

All the reply's make a lot of sense, "unnecessary expense at this time" is the straw that tilted me towards keeping the tires after inspection this spring.
I would still like to know the reasoning for the different grades for the front and rear tires.
