I just (early July 2000) put 4 Michelin LTX M/S P23575R15 105S (to match the stock Firestone rating) on my 97 AWD V8. I went with the P rated instead of LT because a)I don't go off road b)smoother ride, having had LT tires on my other SUVs c)matches P23575R15 105S rating of Stock Firestone Wilderness AT (which is just a Passenger rated M&S P tire).
Got the tires at Costco with their $40 Michelin coupon (was good till July 4th), so $79 each plus $7 each for mounting, etc. Costco gives you lifetime rotation and balance. Family Safety was a Big factor in the decision to replace ASAP.
I'm very happy with the performance of these Michelins so far. The Firestones had various issues. 3 out of 4 had a shallow crack line around the outer circumference of the tread sidewall, 2 were worn unevenly (previous owner neglected to rotate), 1 had a bad plug (slow leak), and all 4 had the beginnings of old rubber cracking; all with only 48000 miles on them.
I don't know if the shallow cracks around the tire circumference is related to tread separation or not.
My old tires were the same as the spare tire (which is still underneath the Explorer), DOT W2HL, which is not part of the Wilderness AT recall. Since I replaced my Stones with the Michelin LTX M/S over a month ago, before all this official news came out, and before Michelin & Ford recommended LTX AT's, I will be sticking with my M/S tires, till they wear out. I contactd Michelin, and they just repeated, like a recording, the Ford recommendation of LTX AT, not M/S. I've seen plenty of M/S on 97-99 Explorers in parking lots, so I believe these will be fine. Michelin will not say either way.
