TIRE GUIDE

Reading the Sidewall

Passenger Car Tire - the letter P indicates this is a passenger tire. Other options besides P would be LT indicating Light Truck. LT Truck tires are designed for heavier loads.

Width of the Tire in Millimeters - The higher the number the wider the tire.

Aspect Ratio - the height of the sidewall compared to the width of the tire. Short sidewalls deliver crisp handling, while taller sidewalls give a smoother ride.

Construction - R indicates the tire is a radial constructed tire. Other markings are used such as D to signify bias ply tires.

Wheel Size - indicates the size of the opening of the tire. You must match the wheel diameter to the tire opening.

Load Index - is part of the service description which designates the load carrying capacity of the tire. Remember to keep the number the same as or greater than the original tires’ load index.

Speed Rating - It means the tire is speed rated on an indoor test wheel to the capable speed of the tire. It is recommended that the replacement tires match the speed symbol of the original tires since these match the speed capability of the vehicle.
