The Dynapro MT RT03 is a rugged tire designed for "true off-road drivers." The V-shaped tread blocks are tapered for better grip in mud or sand and you should see them perform in snow. There are "ejectors" built into the tread grooves to prevent stones from penetrating. Specifically designed shoulders keep dirt from building up and to help prevent damage from impacts.

Just put a set on my new 4runner. What a difference over stock. Small amount of road noise but handling is much better and look is much better. No clearance problems. Haven't driven in snow or adverse weather yet but traction with these tires shouldn't be a problem. Old tires were factory dunlops with 3ply sidewalls so the 4runner wallowed around corners but now the handling is much better and what expected in a body on frame SUV. New tires have 10ply sidewalls. Great tire!
