Cooper Discoverer A/T3 Tires

Product Info

Discoverer A/T3

Built for drivers who split time between pavement, gravel, and changing weather, the Cooper Discoverer A/T3 is a smart all-terrain choice for trucks and SUVs. The Cooper Discoverer A/T3 tires balance everyday road manners with off-road traction, with Robertson Tire offering catalog sizes like 245/75-16, 275/55-20, and 275/65-18 for everything from daily-driven SUVs to harder-working pickups.

This lineup includes LT and passenger fitments in E, SL, and XL load ranges, helping shoppers choose the right setup for commuting, towing, or jobsite use. Cooper’s aggressive all-terrain tread pattern, five-rib tread design, and structured sipes support stable handling, wet traction, and even wear, while select sizes are snow-rated and 3PMSF for stronger winter confidence.

Some LT sizes, including 245/75-16 and 275/65-18, also show a 60,000-mile warranty in the active catalog. If you want a practical upgrade for a midsize pickup, full-size pickup, heavy-duty pickup, or SUV, Robertson Tire can help you compare fitments and book service through Shop Tires or Schedule Appointment.
