Tyre Details

The STT PRO Cooper’s most advanced mud tyre to date. Put through its paces through Australia’s Outback, it’s ready for anything you throw at it!

Key Features

  • Mud Scoops And Mud Release Dimples - Create air pockets to release mud from the tread, giving you exceptional all-surface traction.

  • Flex Groove - Allows the tyre to flex, dampening the impact generated by inconsistent terrain, giving you more flexibility and a smoother ride.

  • Advanced Silica Compound - Formulated with the optimum content of chemically-coupled silica reduces cutting and chipping in off-road conditions whilst improving wet traction. This gives you improved wet traction and longevity.

  • Armor-Tek3 - On top of high tensile construction, the STT PRO features Armor-Tek3 - an additional 3rd ply on an 8° angle. Unique Armor-Tek3 construction is engineered to give you over 2.5 times more tear and impact damage resistance by reducing the rubber gaps by 50% to give you peace of mind when driving off-road. *Compared to standard 2-ply tyres.

  • Micro Gauge™ Siping - Reduce cutting and chipping whilst enhancing traction in wet, soft surfaces, giving you enhanced stability and longevity.

  • Raised Rubber Ribs - Raised Rubber Ribs and angled groove walls work together to eject stones from the tread, giving you reduced stone retention and more grip.
