The Cooper Discoverer ST Maxx is a commercial-grade all-terrain tire engineered for pickup trucks, SUVs, and vans that demand superior toughness and versatility. Designed to handle the rigors of job sites, gravel roads, and off-road trails while delivering confident on-road performance, this tire bridges the gap between aggressive all-terrain and mud-terrain capabilities.

Armor-Tek3 Construction: The ST Maxx features Cooper's proven 3-ply Armor-Tek3 carcass construction, utilizing two 90-degree radial body plies plus a third body ply at an eight-degree bias. This reinforced design fortifies both the tread and sidewall areas, providing exceptional puncture resistance and durability in harsh off-road conditions while absorbing and dissipating tire impact forces.

• Hybrid 4-5 rib tread design reduces road noise and promotes even wear
• Stone ejector ribs and non-parallel groove walls discharge debris and resist stone retention
• Studable design accepts optional #15 metal studs for enhanced winter traction
• High-void tread pattern with multiple block edges provides exceptional grip on soft, uneven surfaces
• In-block siping creates biting edges for wet traction and hydroplaning resistance
• Load Range E construction for heavy-duty applications

The 225/75R16 size offers a 29.49-inch overall diameter with 18.5/32-inch tread depth, weighing 44 lbs. Maximum load capacity is 2,680 lbs at 80 PSI. This tire delivers all-season performance with excellent traction in dry, wet, and winter conditions, making it ideal for commercial vehicles and outdoor enthusiasts who refuse to compromise between on-road comfort and off-road capability.
