All Terrain Tire
Interco Irok Bias
The Interco Irok Bias is built for one job: climbing over stuff that stops other tires cold. Mud, snow, rocks, it doesn't care, it just grabs and goes. Comes in bias and radial builds, plus four non-DOT sticky compounds for competition rigs that never see pavement anyway.

Benefits
You get serious traction in the ugly stuff without sacrificing as much ride comfort or noise as you'd expect from a tire this aggressive. Good pick for crawlers and mud trucks, not so much for your daily highway commuter.
