Ok I don't know a lot about tires, but I had one of the Explorers with the good ol' Wilderness tires, and I got them replaced with the Wranglers, and I have to say I miss hte old Firestones a lot. The Wranglers in my opinion reall suck. Maybe its just my suspension which is getting too loose, but the body rolls like crazy, and when going around turns it feels like I am losing control of the car (Tires pointed one way, car wanting to go another way) . What's a good small tire for the Explorer? I don't want off-road, I want good gas mileage, and small tires for less rotational mass ;)
