Not a MH but my truck that pulls my TT. 275/65/20 Load Range E.
I just put on a set of Cooper ATP tires (built only for Discount Tire) and could not be happier. These tires ride better than the Michelins that came off and have a ton more grip. They weigh 60# each and the worse one took 3/4 oz to balance. (2) of them took 1/2 oz, (1) needed nothing. These tire were made in the US.
The Michelins that came off, the LTX A/T 2, were about useless. Not only did they not have much grip, they were 100% worn out at 35,000 miles - and when I say worn out, I mean would not pass NYS Inspection, riding on the wear bars worn out. This wouldn't be so bad except it's a 60,000 mile rated tire.
If it was pulling the TT full time I could see some shortened life - it pulls the trailer around 700 miles/year. I also have them rotated at every oil change, and they're properly inflated. They're just another example of over rated, over priced, junk Michelins.
Our MH is due for tires next year, and yeah, I'll be looking at Coopers for it too.
As a disclaimer I will say our current MH is riding on Michelins and they have been wonderful. Considering this is the ONLY set of Michelins I've ever owned that I can say that about - and I've owned a lot of them, I will say they are the exception not the rule. Hey, even a blind squirrel occasionally finds a nut. :B
