The dealer put a set of Bridgestone Dueler HL on the truck. Wisper quiet, track dead straight, soft ride, tight in the corners, and at 122,000 miles when they were last measured they had lost only 1/32 of an inch to wear.
However, they were measured because I hit something while driving and blew out the left front tire. Make no mistake, the tires aren't the only issue; a less experienced driver would have rolled that truck over. I managed to stop it, but it was a thrill, and I was cruising on the open road at 60 mph when the tire went down (imagine freeway speeds!).
The new ones are still stones, but I have no complaints. The tire that blew was not defective: it was punctured. But if I were buying, I'd go with Michelin LTX. My personal history with Michelin is that they are a fine tire. It is also the tire of choice from this website on Explorer maintenance:
As hard as that truck was to control with a blow out, I don't plan to let tires on it wear past 50% again, and I'll buy the best tire I can afford in the future (Read: Michelin or BFGoodrich), and donate the old ones to one of the local high school kids driving on slicks.
