I have had a set for several weeks now without any problems at all. In fact, I have bought the older LTX/MS Michelins for all our vehicles during the last fifteen years without any problems.
Also, I have had two test pulls for short distances. While I did not think it was possible, these new LTX/MS2 tires in 265/75/16E handle our travel trailer even better than our previous older design LTX/MS series. And that says a lot.
Time will tell, however, and I hope they continue to perform as well as my other Michelin tires. I sure hope so. Gracious, tires have increased in price since four years ago.
