Features of Michelin XDN2 Pre-Mold Retread Truck Tires. Traction on wet and dry roads is improved with Michelin's Matrix™ siping technology on the Michelin XDN2 Pre-Mold Retread Truck Tires. The over 1,300 biting edges of the 3-D Matrix sipes lock together to give tread blocks extra stiffness for better grip and less tread squirm.
