Do Your Mud Tires Measure Up?

New 9.5-inch wide sizes are light weight and a great value! The STI Out & Back Max tires feature an aggressive tread pattern and true sizing designed to power today’s everything through the mud, from large-bore UTVs to mid-size ATVs, and then get them back in comfort. In sizes from 26 inch up to 32 inch, the Out & Back Max tires use stepped-lug construction and a rugged carcass for trusted performance in the sloppiest conditions.

Do your mud tires measure up to the Max?

More Info



  1. 1.5-inch tread depth in the center, and 2.0-inch depth at the shoulder.
  2. Stepped-lug construction builds lugs for minimum flex and maximum traction.
  3. Sturdy 8-ply carcass for low-psi operation and supreme flotation.
  4. True sizing means the competition doesn’t measure up to Out & Back Max.
