Cooper Discoverer AT3 LT Tires

All-Terrain Tire for Light Trucks

The Cooper Discoverer AT3 LT is designed for light trucks that travel on both paved roads and unpaved surfaces. It suits drivers seeking an all-terrain tire that balances everyday road use with traction on gravel, dirt, and other loose terrain.

Key Considerations

• Vehicle fitment: Match the tire size, load range, load index, and speed rating required by the vehicle manufacturer.
• Driving conditions: All-terrain tread is intended to provide versatility across highway and off-road environments.
• Load requirements: Light-truck tires may be offered in multiple load ranges. Choose a specification appropriate for the vehicle, cargo, and towing demands.
• Ride characteristics: Compared with a highway-focused tire, an all-terrain design may produce different road noise, handling, and fuel-efficiency characteristics.

Choosing a Size

Confirm the complete size printed on the current tire or listed on the vehicle’s tire-information placard. Tires sharing the Discoverer AT3 LT name can have different dimensions and service ratings, so the full specification must be checked before purchase.

Professional fitment is recommended when changing tire size, load range, or wheel diameter. The selected tire should provide adequate clearance and remain compatible with the vehicle’s wheels, suspension, and tire-pressure monitoring system.
