Cooper Discoverer Winter 275/45R20 110V Review

As a dedicated winter tire, the Cooper Discoverer Winter in size 275/45R20 110V is engineered to provide reliable traction and safety when temperatures drop. This specific tire features a 275mm tread width, a 45% aspect ratio (meaning the sidewall height is 45% of the tread width), and is designed for 20-inch wheels. It’s a robust choice for drivers seeking confident control through the colder months.

Winter Performance

The Cooper Discoverer Winter is built for challenging winter conditions, offering strong capabilities on muddy and snowy surfaces. Its tread compound and design are specifically developed to maintain flexibility in low temperatures, ensuring enhanced grip and reliable handling. As a dedicated winter tire, it is thoroughly tested and certified for winter suitability, providing the necessary traction for safe driving when the weather turns severe.

Dry Performance

While the Cooper Discoverer Winter excels in cold and wintry conditions, its design prioritizes snow and ice traction. On dry pavement, like most dedicated winter tires, you can expect a slightly softer ride and less responsive handling compared to an all-season or summer tire. This is a trade-off for superior performance when temperatures drop below 45°F (7°C).

Wet Handling

This tire achieves a ‘C’ rating in the EU wet grip class, indicating a competent level of performance on wet roads. Its specialized tread pattern and siping work to evacuate water and slush, helping to reduce the risk of hydroplaning and maintain grip during rainy or thawing conditions, which are common in winter.

Technical Specifications

The Cooper Discoverer Winter 275/45R20 boasts a load index of 110, meaning each tire can support up to 1060 kg (2337 lbs). It also features a speed index of V, rated for speeds up to 240 km/h (149 mph). This tire is classified as an entry-level, budget-friendly option in the C1 category, delivering solid performance without breaking the bank.

An important feature is its rim protection, which is a reinforced area on the tire’s sidewall specifically designed to shield your wheels from curb scratches and minor impacts. This tire does not include a run-flat feature.

The “XL” designation signifies a reinforced construction, offering a higher load capacity than standard tires of the same size. If your vehicle requires Extra Load (XL) tires, you’ll find this information in your vehicle’s owner’s manual or on the door jamb placard.

Each Cooper Discoverer Winter 275/45R20 tire weighs approximately 15.25 kg (33.62 lbs).
