The STI Outback Max true-to-measure size 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 tire’s tread, maximizing traction and tire strength.
