Discoverer STT Pro

Built for drivers who need real mud-terrain grip, Cooper Discoverer STT Pro is a rugged choice for lifted 4x4s, trail-focused SUVs, and hard-working trucks. The Cooper Discoverer STT Pro tires combine aggressive off-road traction with road manners that still make sense for everyday driving, with Rocky's Tire & Service offering popular fitments like 265/70-17, 285/70-17, and 275/65-20.

For SUV and pickup owners heading into mud, rock, and rough backroads, this LT tire is designed around Armor-Tek3 carcass construction, large depth side biters, alternating cleats and scoops, mud release dimples, and anti-stone retention ribs for added toughness and traction. It fits common truck-ready sizes such as 235/85-16 for heavy-duty applications and 265/70-17 for many off-road builds.

At Rocky's Tire & Service, you can move from research to installation with help from local experts. Start with Shop Tires, book Schedule Appointment, or add services like Wheel Balancing and Wheel Alignment Check to get your new mud-terrain setup ready for the next trip.
