About the AMP Terrain Attack AT A

The AMP Terrain Attack A/T A is an all-terrain tire built for Jeeps, light trucks, and SUVs that need to perform both on paved roads and off the beaten path. Carrying the Three-Peak Mountain Snowflake certification, it handles severe winter conditions alongside everyday driving demands, making it a versatile choice for drivers who don't limit themselves to one type of terrain.

A symmetrical multi-block tread pattern balances on-road smoothness with off-road grip, while staggered tread blocks work to eject loose dirt, sand, and debris from underfoot. Self-cleaning grooves actively channel out mud, water, slush, and snow to maintain consistent traction and help protect the casing for long-term durability. The tough sidewall adds an extra layer of traction and protection across dry, wet, and winter surfaces. The tire is backed by a 40,000-mile limited tread life warranty.
