I run Michelin on the steer axle and Goodyears on the drive and tag. Both Michelin and Goodyear are the only two mfgs that add compounds to their rubber to stave off the effects of UV damage according to their ads. They are the only two mfgs that build RV tires...the others are TRUCK tires. I have an RV so I buy RV tires....you can save some money buying truck tires. I've had excellent wear on all the tires on my coach...over 50,000 miles.
If you're going with Michelins, (my recommendation) look into the FMCA program. You'll save big bucks....I believe my 315s were a tad over $500/per tire....Dennis
