All Season vs All Terrain Tires Tested: Do You Actually Need an All Terrain?
The Pirelli Scorpion XTM AT is the best all-terrain I have tested and the one that gives up least to an all-season on the road. Off road it had no real grip advantage over the all-season here, but it steered better in the sand and on the side hill, stopped shorter in the snow and, most importantly, came through the same off-road abuse looking fresh. Buy it if you regularly drive rough trails, dirt roads or mud and want a tire that keeps working, and looks the part, mile after mile.
