What 245/35R21 tires means
The 245/35R21 code describes the tire's shape and fit. The first number, 245, is the section width in millimeters (about 9.65 inches) measured across the widest part of the tread. The 35 is the aspect ratio: the sidewall height is 35% of the section width, which works out to roughly 85.8 mm (about 3.38 inches). The R means radial construction, and 21 is the wheel diameter in inches that this tire mounts to.
Put together, a 245/35R21 stands about 27.75 inches tall overall and turns roughly 727 revolutions per mile. Those figures matter to a buyer: overall diameter affects speedometer accuracy and how the tire clears the fender and suspension, while the short 35-series sidewall trades some ride comfort for crisp, responsive steering. Staying close to the factory diameter keeps your speedometer honest and avoids rubbing.
Vehicles & uses
This is a large-diameter, low-profile size. Combinations like it are commonly fitted to luxury sedans and sports cars that prioritize precise handling and responsive steering, as well as sport-oriented crossovers running larger 21-inch wheels. Because exact fitment depends on your specific vehicle, wheel offset, and trim, confirm the size against your door-jamb placard or owner's manual before ordering.
Brands & options in 245/35R21 tires
The in-stock lineup covers premium, performance, and value tiers. On the premium and touring side, Continental offers the EcoContact6 Q, and Pirelli brings the P-Zero (PZ4), a run-flat P-Zero, and the cold-weather Winter SottoZero Series 3.
For performance driving, Toyo supplies the Proxes Sport 2, while EV-focused all-season options include the Kumho Solus TA91 EV and the Hankook iON evo AS IH01. Value-minded shoppers can look at Lionhart with the LH-FIVE, Lexani with the LX-TWENTY and VOLT-EC, plus the Advanta HPZ01 and the Accelera PHI R. Falken, Arroyo, and Ironman round out the selection.
How to choose
Season comes first. Summer tires deliver the sharpest dry and wet grip in warm conditions; all-season tires balance year-round usability; and dedicated winter tires (like the SottoZero above) are built for cold, snow, and ice. Never mix seasons across an axle.
Treadwear & UTQG ratings help compare expected tread life, traction, and temperature resistance between models. Load index and speed rating should meet or exceed your vehicle's original specification; several options here carry an XL (extra load) marking and high speed ratings. Finally, check each tire's mileage warranty before buying, since coverage varies by model.
