18 INCH TIRES

Check out Pirelli’s broad selection of 18 inch tires for your vehicle. This catalog offers r 18 tires (for rims that are 18 inches in diameter) in a variety of heights and widths. You’ll also find tires for all driving styles: high-performance, all-terrain, or summer tires. Also, our range of winter tires, snow tires, and all-season tires can help keep your car or light truck firmly on the road in all weather conditions.

If you need to know what your 18 inch tire width and height is in order to choose the right product, look on the side of your current tires or on the placard on the driver’s door post. You’ll find a set of eight numbers and letters—for example, 285 75 r18. In this case, the car tire is 285 mm wide, has a height that is 75% of its width, and fits rim size 18 (in inches).

Now that you know how to find the height, width, and inside diameter of the tires that fit your car, you’re ready to find just the right tire for you. Browse our catalog of 18 inch tires and click the correct size for your vehicle.
