We really haven't got enough mileage on these tires to make a definitive call on it yet. Our previous tires were BF Goodrich Long Trail Tours. OEMs were Dunlop AT-20s.
Let me say the Dunlops were horrible. The 4Runner weaved all over the road. It really felt unstable at highway speeds. In the rain, it had fair traction. It was miserable in the snow. I have to say that I really felt they were unsafe and had them replaced at 13K miles.
The next set of tires were the Long Trail Tours. They had excellent traction on dry roads, wet roads, snow, and sand. We never felt like we were not in control. But at about 15K, one of the tires developed a pull to the left. Not sure why. But when rotated to the rear, steering was fine. Up front, it pulled. It also got a bit noisy at 20K but it wasn't bad...especially after the Dunlops.
We replaced them with these Michelins. Let me say that we are completely stunned at how much better these tires are. The 4Runner is extremely quiet now and tracks like it never has before. The ride is much smoother too. The wife asked me why we didn't get these tires right off the bat. I told her quite honestly that it was the price. I didn't think they were worth it at the time but I do now.
Now we haven't taken them thru snow yet but fall is here and I'll update later. But for now, we are very impressed!
