About This Tire

The Cooper Discoverer HT3 275/65R18 is an all-season highway tire, designed for pickup truck, full-size SUV, van and commercial vehicle drivers who prioritize long tread life and reliable traction in everyday driving. Its tread design and compound focus on durability, wet weather performance, and maintaining stability under the demands of heavier vehicles.

The tire features a high-silica tread compound molded into a symmetric pattern with continuous shoulder ribs that resist irregular wear from frequent stopping and starting. Four wide circumferential grooves channel water away from the contact patch to prevent hydroplaning, while interlocking 3D Micro-Gauge siping provides tread block stability and creates biting edges for wet and light snow traction. Driver feedback points to strong dry road handling and impressive tread longevity, with solid wet weather performance and comfortable ride quality in daily use.

Compared to performance-oriented tires, it emphasizes comfort, stability, and long-term usability. Overall, it's a solid choice for trucks and SUVs used primarily for highway driving and daily transportation in varied weather conditions.
