1. Pirelli Scorpion Winter - Best Winter tire

Drive comfortably this winter season by pairing your vehicle with the best winter tires. One of the ways to do so is to purchase the Pirelli Scorpion Winter, the best 275/40R21 tire that is eligible for an excellent SimpleScore of 9.2. As you brace up for survival at temperatures below 45 degrees Fahrenheit, this dedicated winter tire will help you combat snow, ice, and slush in good measure. Wide grooves and dense sipes enable them to offer a high amount of traction due to their dense sipe layout, which helps grip even during turns, and the tread’s circumferential grooves provide hydroplaning resistance. Thanks to the above, this 275/40R21 tire earns an outstanding average traction SimpleScore of 9.9. The circumferential grooves enhance braking and handling on wet roads, allowing the tire to receive a 9.9 yet again, this time for handling. You’ll get better stability and control in deep snow due to the Three Peak Mountain Snowflake certification. Although winter tires do not last very long, the high tread depth and the directional tread pattern enable the Scorpion Winter to garner an average longevity SimpleScore of 8.0.

2. Hankook Ventus S1 evo3 SUV (K127C) - Best UHP Summer tire

For obtaining a high-performance tire that offers a great combination of comfort and agility, consider UHP summer tires such as the Hankook Ventus S1 evo3 SUV(K127C). This 275/40R21 tire is designed for optimum performance at temperatures above 45 degrees Fahrenheit and is suitable for an average SimpleScore of 8.5. As a W-rated tire, the Hankook Ventus S1 evo3 SUV (K127C) features stiff outside blocks and shoulders to provide grip during precise steering reactions, resulting in an average handling SimpleScore of 8.7. The asymmetrical tread pattern is also helpful for generating dry grip. Additional inner blocks improve drainage for better hydroplaning resistance and better wet grip, enabling us to award an average traction SompleScore of 8.4. High heat dissipation prevents the 275/40R21 tire from weakening beads and belt structures, leading to an average longevity SimpleScore of 8.3.

3. Continental CrossContact RX - Best All-Season tire

Another great idea is to find an all-season tire that ensures peace of mind through short stopping distances on wet roads and is suitable for year-round traction on all surfaces. One such tire that does not have to be changed during the year is Continental CrossContact RX. Drivers will love the quiet ride and the great traction from these 275/40R21 tires that are suitable for an excellent average SimpleScore of 9.2. While the CrossContact RX has been built to stop within short distances, its high tread depth leads to a tremendous average handling SimpleScore of 9.5. Innovative sipe technology is responsible for good traction in snowy and wet conditions, and when in combination with the tread depth, this 275/40R21 tire receives an amazing average traction SimpleScore of 9.7. A low rolling resistance design decreases fuel consumption to save drivers money and time at the fuel pump, resulting in an average longevity SimpleScore of 8.4. Sipe placement and an innovative design decrease road noises to ensure a quiet and smooth ride.

4. Nokian Hakkapeliitta R5 SUV - Great Winter tire

All-season tires aren't a safe choice for those who live in areas with a lot of snow and ice and extremely cold temperatures since they aren't designed to withstand harsh winter weather. The Nokian Hakkapeliitta R5 SUV is our recommendation as a winter tire in these types of climates, suitable for an average SimpleScore of 9.1. The directional tread design of the studless Nokian tire has slanted grooves that quickly slush water out of the surface to prevent aquaplaning. Wide, deep grooves and thick sipes on these winter tires are essential for providing a good grip and facilitating easy navigation of slick terrain. For greater traction and grip, the Arctic Grip Crystals serve as studs and add sharp, cutting edges, and the 275/40R21 tire gets an excellent average traction SimpleScore of 9.9 as per the above. It features a Double Block Grip on the shoulders for improved control on slick surfaces, adding extra biting edges and rubber, leading to an average handling SimpleScore of 9.0. The Three Peak Mountain Snowflake certified tire has Aramid Strong Sidewalls for towing heavy loads, as well as a material that resists cuts, punctures, and chipping. As per the above, it receives an average longevity SimpleScore of 8.5.

Last on this list is the Dunlop SP Sport Maxx, commonly available as an OEM tire for the likes of Jaguar, Audi, and Mercedes-Benz. Designed for use in warm weather (temperatures above 45 degrees Fahrenheit), this UHP tire provides great performance and stability, enabling it to get an average SimpleScore of 8.4. An Integral Rubber Matrix in the 275/40R21 tire’s tread allows it to offer great braking and acceleration performance.
