Cut & Chip‑Resistant Tread Compound for Mixed Terrain Use. Engineered with a proprietary compound, the Cooper Discoverer S/T Maxx Tire (33" - LT285/70R17) resists cuts, chips, and abrasions commonly encountered on gravel, rock, and dirt surfaces. The tread features a hybrid 4–5 rib pattern with stone-ejector ribs, non-parallel groove walls, and deep tread blocks that actively shed debris and prevent stone drilling. This design makes the tire ideal for drivers who split time between highway and off-road environments, offering durability without sacrificing on-road manners.
Balanced On‑Road and Off‑Road Traction with Aggressive Aesthetics. In LT285/70R17 sizing, the Cooper Discoverer S/T Maxx Tire (33" - LT285/70R17) measures approximately 33 inches in overall diameter with a section width of about 11.5 inches, delivering a wider footprint for improved stability and a bold, aggressive stance. The tread design offers strong dry traction, capable wet performance through wide grooves and in-block sipes, and reliable handling across varied conditions.
Hybrid Rib Design for Noise Control and Even Wear. Despite its rugged capabilities, the Cooper Discoverer S/T Maxx Tire (33" - LT285/70R17) is designed with a hybrid 4–5 rib tread structure that helps minimize road noise and promote even wear across the contact patch. This thoughtful design allows the tire to deliver a more refined ride on paved roads, making it a versatile choice for vehicles that transition between trail duty and daily driving.
