In all three true-to-measure sizes, the STI Outback Max uses an 8-ply rated carcass that allows low-psi operation, superior flotation, and the durability riders demand, while keeping the weight competitive
The aggressive tread pattern features center lugs measuring 1.5 inches deep, with 2.0-inch deep lugs at the shoulders. These lugs are built with a stepped-base design that minimizes flex across the tires tread, maximizing traction and tire strength
The Outback Max tires complement STIs line of Outback AT and XT tires, a multi-size lineup of all-conditions tires currently available in 25 inch up to 28-inch sizes
