1 tire line. 325/50R15 tires sized to your wheels and your car.

325/50R15 means a 325 mm section width, a sidewall 50 percent of that (163 mm) and a 15 inch rim, which works out to 27.8 inches tall. Whether 325/50R15 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 325/50R15, from Nitto. By type that is 1 performance summer. 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 325/50R15 lines that do both.
