The Michelins on my 07.5 pretty much suck, dry rot cracking on the side walls even the spare. I am looking at the Brigestone REVO's, The dueler AT's (D range 285's at 65 psi all of the way around) on the 96 have been worth thier weight in gold. On the 07.5 I run 75 psi front and rear all of the time and at 28K have no noticable tire wear, they are all 4 at about 60% of useable tire life left, unless the side walls get worse. Michelin says "we have never seen this problem before and there is no warranty on the OEM tires". I have had 2 sets of these that have done the same thing.
