Maximize Your Mud Potential

The legendary mud performance of the Out&Back Max tire is now available to mount on 20-inch UTV wheels. The new lightweight, 9-inch wide Out&Back Max’D tires are here to serve your mud lifestyle with all-around high-performance traction and aggressive style.

The new Out&Back Max’D features stepped, 1.5-2.0 inch deep all-terrain tread that tracks through mud and cleans well, plus a durable and lightweight 8-ply-rated carcass, and a deep rim guard that will protect your stylish wheel investment. Three sizes are available — 33-inch, 35-inch and 36-inch — all to wrap around 20-inch wheels like the STI HD10, and the new 20-inch HD4.

The STI Out&Back tire family includes a range of sizes for ATVs and UTVs, and they’ve proven to be all-around performers, with the Max tires excelling in deep mud.
