STI ATV Tires

A bigger, bolder and more extreme mud tire, the all-new STI R4 is specifically designed and engineered for high performance UTV applications.

 

  • Deep lugs, 1.75 up to 2 inches.
  • 9 inches wide, and tubeless.
  • 8-ply radial.
  • Super deep rim guard.
  • Designed for UTVs.

 

This 8-ply rated, tubeless radial carcass tire measures 9 inches wide. The R4 features super-deep lugs - 1.75 inches at center and 2.0 inches at the shoulder - angled to optimize traction performance both forward and in reverse. This new tire is constructed for durability, too, with a rubber compound built for abuse. The R4’s deep rim guard protects your wheels as well. Other tires may look the same, but only the R4 enters the mud with lugs this deep and a carcass this strong and at a comparatively low weight.
