Darrell,
I just checked on the FMCA sight and this is what I found…
They have a Michelin Advantage Program… and there is a brochure showing common RV sizes… the 365s were not listed on the brochure… then it said if your size is not listed please contact us :
membership@fmca.com or call 1-800-543-3622
Hope this helps… BTW you do have to be an FMCA member to qualify for theMichelin Advantage Program.. I have read where several folks have saved quite a bit through the program.

SERVICE LIFE FOR TIRES
There has always been debate and confusion regarding tires and when they should be replaced. The article in this link explains Michelin’s opinion on this topic. From a class on tire forensics it became very clear there are numerous causes for tire failure. It also was very clear from the class minor issues we never considered will cause failures, some catastrophic. While they made it clear when speaking with 2 field service technicians that they would strongly suggest removing tires after 7 years, the article linked below does state that ten years is an absolute limit, but it is also stated that after 5 years the tire should have at least annual inspections.
An inspection is far more than looking at it and perhaps running your hands over it to feel for clues of possible problems. The tires need to be removed from the wheel and a detailed inspection is required. Indications of running the tire when flat or at low pressure require the tire to be taken from service. Any damage to the inner liner allows air to begin traveling between the layers with the end result to be a failure, so the inside of the tire has to be carefully inspected. If the tire had a repair it is very important the repair is made to the Michelin standards and just putting in a plug is unacceptable,
Tread depth should be measured and it has to be within 2/32” from the deepest to the shallowest.
Not only the tire needs inspection, but so does the wheel. Tires and their bead have been damaged by a bead that is not clean and free of defects.

According to all the experts 95% of all tire failures are due to under inflation. More is better thn less.

I’ve looked at their chart before, but I feel a little more comfortable running a little higher psi.
The Offiical Chart would have me at: 95psi S/ 85psi D/ 80psi T.
What I run at: 105psi S/ 95psi D/ 85psi T.

Mine are identical Tim..

The book says 115, 90, 100. I run 120, 100, 100. I still run 315s all the way around. I was 500 pounds over on the front axle, so I upped the tire pressures in the front. And I just did not like the way the drive axle looked at 90 psi.
-
Our coach is an anomaly with front axle weight per tire, drivers steer weighs 7725, and passenger is at 7569 equalling less than 15,400. The Michelin chart lists psi of 85 for our 365/70/22.5. Previous owner had Kaiser in Eugene do the upgrade via Marathon. Jon, I’m still struggling using less air than the 100 psi we re currently running

We discussed inflation pressures in the seminar in detail. All others in the seminar had truck fleets and the tires are inflated to a pressure suitable for the max load on the tractor and trailer. The problem is the tire contact surface is determined by the pressure and load carried, with the ideal being the pressure shown in the chart. When under inflated it was clear a tire could be destroyed. When over inflated the tire cannot give the performance it was designed to provide and lightly loaded tires that are over inflated can sustain some wear issues.
Wear issues are likely not our concern, but a fleet that can stretch its tire life from 140,000 miles to 175,000 miles can benefit greatly. Just be aware an over inflated tire with the smaller footprint is not going to provide the best stopping distance or resistance to skids.

On page 36 of this document listed below inflation pressures are discussed. There is an allowable increase of 10%.

Per,
Tom & I are running 365’s on S/T.

Six months is not too old. As long as they are the same date. Your warranty
will start with the install date.
I would get my tires through NTCS. A PC advertiser.

I agree with John Wade. Definitely the way to go. Worked great for us and was easy to deal with.

Thank you both. I was just a little alarmed about them being 6 mo old already .thanks for your thoughts Jim
