The STI Outback Max is one of the top selling mud tires on the ATV / UTV market. These tires will rip through the mud while giving you a smooth ride on soft packed trails. These are the ulimate tire for all of our trail enthusiasts who love to hit every hole along the ride. 

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.
