Tire Features

Solid Traction in Dirt and Gravel

Wide open grooves in the tread grab and release soft surfaces, while the narrower center grooves help to provide stability.

Strength that Lasts the Test of Time

Strong shoulder design features such as scooped tread edges, wide tread grooves, and sidewall hook pattern all help provide grip and traction for the life of the tire.

Protection from Demanding Environments

Strategically designed tread lugs help to resist cracking, tearing, and rounding of the tread. Ledges between the lugs help prevent stones getting stuck in tread.

No Slip, No Problem

A specialized rubber compound and wide lateral grooves help plow through water.

Great Snow Traction

Textured edges on the shoulders grab into snow to help provide traction in harsh winter conditions.

Three-Peak Mountain Snowflake Designation

Tires designed for use in severe snow conditions and meet specific snow performance test requirements.
