1 tire line. 215/30R20 tires sized to your wheels and your car.

215/30R20 means a 215 mm section width, a sidewall 30 percent of that (65 mm) and a 20 inch rim, which works out to 25.1 inches tall. Whether 215/30R20 works comes down to the wheel width it mounts on and how far it lands from the height the car left the factory with.
1 line carries 215/30R20, from Lexani. By type that is 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 215/30R20 lines that do both.
