The Hercules Avalanche TT is a winter tire engineered for pickup trucks and cargo vans. Zigzag circumferential grooves and saw-tooth features trap snow in the tread for better snow-on-snow traction, and Snow-Grabber grooves add more bite.
Full-depth siping improves grip on snow and ice, and the tread accepts optional stud pins for extra traction.
This 275/55R20 size carries a 117T load and speed rating with extra load (XL) construction. It has 12.5/32-inch tread depth, a 50 psi maximum inflation pressure and an overall diameter of about 32.01 inches.
