255/35R21 Tire Size

In general, tires with 255/35R21 dimensions are high performance tire sizes, typically used on sports cars and luxury vehicles. The first number (255) is a section with a width of 255mm. The second is an aspect ratio of 35% from the pattern width.  The R indicates that it is a radial tire. While the last number means that fits on 21-inch diameter wheels. Radials are a common type of construction that offers better ride comfort, durability, and fuel efficiency. Footprint with a section of 255mm width provides more contact patches with the road, resulting in increased grip and road stability in corners. In addition, a low profile can help improve ride comfort while maintaining an aggressive and sporty appearance.

Tires with this dimension can be found frequently on sporty vehicles such as Tesla Model Y, Infinity Q70, BMW Alpina B7, Audi S7, and Aston Martin Vantage, but also on other sports cars.

Best 255/35R21 Tires

Firstly, Michelin Pilot Alpin PA4 is a high performance studless winter tire. It is suitable for many luxury and sports cars. This model features a unique rubber formula that uses full silica-based, along with sunflower oil-enriched Helio Compound+ technology. The main role of these is to provide more flexibility in low temperatures. The advanced compound is molded into an asymmetric winter tread pattern designed to boost acceleration, braking, and handling performance. In addition, in the production of this one, Michelin uses Evergrip technology. It helps to maintain its grip in severe winter. All of these make the 3PMSF certification possible. It means that performs in severe snow service requirements. Best of all, Michelin backs this one with 6 years of standard limited warranty, or 30,000 miles tread life.

Secondly, the Continental SportContact 6 is a Max Performance(UHP) summer tire. It meets the needs of millions of sports coupes, luxury sedans, or SUVs. This model benefits from an advanced summer Black Chili compound molded into an asymmetric tread pattern combined with a strong outboard shoulder with a closely spaced intermediate rib to provide maximum grip and extra lateral stability at a high speed range. To ensure a controlled feel and responsive turn-in, engineers use continuous center ribs. This model stands out with ContiSilent technology that inhibits inside noise on all road surfaces. In addition, ContiSeal seals a damaged tread. Moreover,  deep and linear grooves and lateral notches offer great water evacuation from under the footprint, thus reducing the risk of hydroplaning. Limited sizes come with an SSR system (run flat).
