Tires (again)

Just asking the expertise of the forum. I bought a used 2010 Jayco Melbourne. Has a set of Michelin LT225/75R16. My question is the previous owner stored this Motorhome in a garage for the first six years unless camping. I know all about the 5-6 year rule, but a set of 6 of these is around $3,000. Do you think with the indoor storage I would be safe going longer? They only have 17k miles on them. Thanks. Just looking for the expert opinions of the members

Our 2007 Phoenix Cruiser motor home HERE is always garage kept when not in-use. The house portion is built on a 2007 E350 with the same original tires as you have. They now have 30,000 miles of use. So our Michelin LTX M/S LT225/75 R16 tires are now 9 years old. My plan is to get at least 3 more years, maybe longer pending if I see significant sidewall or between-thread cracking. So far no cracking of any kind, not even very minor. They still look like new and are wearing well too.

If your rig is on the smaller/lighter side, I think you can get another 6 years of regular use. Just watch for sidewall or between-thread cracking or other concerns. If your class C/B+ rig is 28-32 feet long and over-loaded, I think you are still safe to use them, but consider replacing them a few years earlier, again assuming they pass inspection. I feel shorter/lighter rigs can stretch tire-life for longer periods because they carry less weight with lower PSI.

Our first motor home, we owned for 24 years. It too was garage kept, and it was very light weight. We sold it with it's second set of tires.
