The DX440 Tire has a Gen 2 carcass and profile design for lighter weight, less rolling resistance resulting in the "fastest" tire of the line. The decreased weight also reduces drive line stress. Flexible carcass and medium compound excels on hard pack and semi loose terrains. 8-ply radial durability and superior bump absorption. Non directional, multi angle tread blocks and sharp shoulder angle offers precision handling. Super deep rim guard offers unmatched wheel lip protection.
