We have 255/70R22.5's on our 36' HR Endeavor. We had quotes of around $3400 to replace the 6 tires. After some checking around we decided on Bridgestone R250ED, the quotes were still in the $3400 range. Went to Speedco, the oil change folks, spent $2300 and change for all 6 tires! We saved about $1000 and LOVE the tires. They ride and track very well.
I retired from the tire business after owning a tire store and have sold most brands of tires. The Michelins were never a consideration for my replacement. I had a Michelin Rep once tell me "Michelin has never made a defective tire". I had to call BS. With all the tires they have made I gotta believe that defective tires have left their factories. The attitude told me that Michelin just may not have the best after sale service, should there ever be a problem.
Speedco only deals with OTR trucks and diesel MHs. They are equipt and seem well trained. I have had great service from the one in Eloy, AZ with the tires at a great price as well as oil changes for the RV and the Onan.
