Product Info

Discoverer A/T3

Cooper Discoverer A/T3 is built for drivers who want all-terrain confidence for commuting, gravel roads, and changing weather on light trucks and SUVs. The Cooper Discoverer A/T3 tires give Rocky's Tire & Service shoppers a versatile mix of LT and passenger-style fitments, with available sizes including 245/75-16, 265/70-17, 275/55-20, and 275/65-18.

For SUV and full-size pickup owners, this model balances everyday road manners with off-pavement traction. Select sizes are snow-rated and offer 3PMSF severe-snow capability, while LT load range E options are a smart fit for towing, hauling, and rougher-road use. Cooper features like Even Wear Arc Technology, Whisper Grooves, and Stone Ejector Ledges support even wear, stable handling, and a more composed ride.

If you want help choosing between a heavier-duty LT size and a more everyday SL or XL fitment, Rocky's Tire & Service can help. Start with Shop Tires, book service with Schedule Appointment, or get local fitment guidance through a Tire Consultation.
