Our heaviest weigh-in of our small motor home, per-tire weight was as follows.
2055 per rear tire
1630 per front tire
This means I can safely consider standard "E" (115R) rated tires because we have plenty of margin to spare.
I am strongly leaning toward paying more money to get the Michelin Agilis CrossClimate tires which have a max load rating of 2680 per tire. I fear heavier-duty commercial grade tires will yield a rougher ride. Our original Michelin LTX tires lasted us 14 years, and continue with no cracking due to indoor storage. I can't ignore that. I also like the idea of Made-In-USA to support our economy and to better assure quality control, especially concerning rubber compound formulation that is impossible to inspect. Like someone here said, the savings buying tires made over-seas (like Thailand or Vietnam) is debatable, most especially in the case with motor home tires that everyone has issues and concerns over.
There are two different Michelin Agilis CrossClimate, the standard 115R and the "C" commercial grade version.
