Tire Design

  • Even Wear Arc Technology™

    Tire shape engineered to strategically balance pressure at the tire-to-road contact area promoting even on-road treadwear and superior handling.

  • Whisper Grooves™

    The "Whisper Groove™" provides a sound barrier that reduces road noise.

  • Rugged Traction Shoulders

    Rugged traction shoulders provide increased off-road traction for boulder crawling and mud handling as well as additional resistance to abrasion and punctures.

  • Stone Ejector Ledges

    Ledges easily eject stones and gravel, protecting the tire from stones drilling into carcass and maintaining a clean tread for enhanced road traction.
