IROK-Bias

Conquer Any Terrain with the Interco IROK Off-Road Tire

The Interco IROK is a force to be reckoned with off-road, meticulously engineered to dominate challenging environments. Here's why off-road enthusiasts swear by the IROK:

Unmatched Off-Road Performance:

  • Legendary Interco Three-Stage Lug (TSL) Design: Provides exceptional traction in mud, snow, and on rocks.
  • Scooped Lugs, Blade Sipes, and Cut-Resistant Compounds: These features work together to dig deep and deliver superior grip in loose surfaces.
  • Special Sidewall Features: Enhanced protection against punctures and abrasions from rocks and roots.
  • D.O.T. Approved (Most Sizes): Legal for street use, making the IROK a versatile choice.
  • Smooth Ride and Lower Road Noise: Enjoy a surprisingly comfortable ride for an off-road tire, reducing driver fatigue on long journeys.
  • Available in Bias Ply and Radial Constructions: Choose the construction that best suits your needs for durability and performance.
  • Wide Range of Sizes: Nearly 50 size combinations to fit most vehicles, with options for both on and off-road use.
  • Directional Tread: Both Bias Ply and Radial IROK tires are directional tires. Be sure to follow the recommended mounting direction for optimal performance and tread wear.
  • Made in the USA: Interco IROK bias ply and radial tires are both proudly manufactured in the USA.
  • Non-Directional IROK Option: For those seeking a non-directional tread, consider the Interco IROK ND, the IROK's "little brother." The IROK ND is a radial tire, constructed in Thailand. Click here for more information on the Interco IROK ND.

Important Note:

Bias Ply Air Pressure: Bias ply IROK tires require stricter attention to air pressure for safe highway use. Be sure to maintain the recommended air pressure for your specific tire size and load.
