The Discoverer Road+Trail AT is Cooper's On-Road All-Terrain tire, built for the drivers of pickups, work vehicles, and SUVs who need a tire with the rugged durability to keep up with their active lifestyles. Engineered to tackle dirt, gravel, mud and the urban jungle, the Discoverer Road+Trail AT combines off-road prowess with agreeable on-road comfort and year-round traction. It even handles light snow well enough that it meets the tire industry's severe snow service rating requirements and earns the three-peak mountain snowflake (3PMSF) symbol.
