The 40x13.50R17 Trail Grappler rock race tire was developed to provide enhanced stability in high speed desert terrain and increased traction in the rocks. The design is based off the Trail Grappler street tire with slight modifications to the sidewalls for increased puncture resistance and a soft yet chip resistant compound that holds up to high speeds and provides exceptional traction in rocks.
