Our '03 MH came with Michelin Junkers, one which blew out while parked in our garage at a very young age. (The steel cords were rusted - great) We replaced them all with Yokohamas and were very satisfied with them.
Our current MH has Michelins and they have been fine.
Buying Michelins is kind of like playing Russian Roulette, they go round and round but you never know when they'll go BOOM! You did well with yours.
My last truck came with Michelins, rated for 60,000 miles. At 35,000 miles they were bald. Always properly inflated, always rotated on schedule, just bald at 35,000 miles. I'll hand it to them though, at least all 4 were worn to the same degree of baldness. At least that junk was consistent.
In case there was any question, I'm not a Michelin fan. :B
Enjoy the Yokohamas, I think you'll be happy.
