πŸ’‘ Is the Cooper Discoverer S/T Maxx 315/70R17 a Good Tire?

The Cooper Discoverer S/T Maxx 315/70R17 is an all-season commercial all-terrain tire designed for full-size SUVs and light trucks. It delivers solid off-road traction and adequate on-road handling thanks to its aggressive tread blocks and silica-tread technology optimized for varied terrain. Ride comfort is firm with noticeable road noise at highway speeds, typical of heavy-duty all-terrain designs. Tread life is competitive for commercial use applications. Rated Good by TireRack based on 72 consumer surveys, it excels in durability for work applications but lacks the refined on-road manners of highway-focused tires. Currently priced from $430.99, it is available through major online tire retailers.

About This Tire

The Cooper Discoverer S/T Maxx 315/70R17 is an all-terrain tire designed for pickup truck, SUV, and van drivers who prioritize off-road capability and year-round traction in demanding conditions. Its tread design and compound focus on cut-and-chip resistance, stone ejection, and maintaining traction across loose terrain while delivering confident performance on paved roads.

The tire features a symmetric hybrid four-five rib design with an open tread pattern and multiple block edges for enhanced grip on soft soil, rocks, and gravel. Stone ejector ribs and non-parallel groove walls help prevent rock retention and potential damage, while in-block sipes create biting edges for wet traction. Driver feedback points to strong wet weather performance and excellent comfort levels, with reliable dry handling and solid durability for extended use.

Compared to highway-focused tires, it adds significant off-road traction while maintaining reasonable on-road manners. Overall, it's a solid choice for work trucks and recreational vehicles used for mixed driving that includes job sites, gravel roads, and off-road adventures.
