7 tire lines. 315/30R21 tires sized to your wheels and your car.
315/30R21 means a 315 mm section width, a sidewall 30 percent of that (95 mm) and a 21 inch rim, which works out to 28.4 inches tall. Whether 315/30R21 works comes down to the wheel width it mounts on and how far it lands from the height the car left the factory with.
7 lines carry 315/30R21, from 4 brands (Michelin, Continental Tire, Kumho and Pirelli). By type that is 6 performance summer and 1 all season. The tire has to stay near your car's stock height and mount on your wheel width, so pick the car and the wheel set and the page keeps only the 315/30R21 lines that do both.
