I have had unbelievable long wear from the LTX M/S2s. I have heard some people don't like the Defenders. That looks like the good old Michelin highway tread. One of my favorites.
Deep edge tread that rounds less than most brands. Gives you longer life even if alignment won't stay in and you get edge wear.
You can notice the wear then rotate especially if one front wears inside and one wears outside...then when it gets to be over half, I have them dismounted and flipped.
I got more life out of the LTX M/S2s than any other tire I ran on several vehicles.
I had BF Goodrich Commercial (TA I think), General Grabber and Cooper Discoverer 225-65-16 E, Firestone Transforce HT, Laufenn . The Laufenn is my 2nd favorite.
They are slightly more aggressive tread (don't like because this vehicle is ONLY on highway) but have a more squared block big truck 4x4 tire look. They have worn better than all but the Michelins.
