General Tire Info
Before you replace the tires on your car, you need to at least know the size and speed rating of the tires. Fortunately this information is embossed on the side of tires, and below we show you how to read these details. Once you have this information, have a look at the tires we stock, then visit your nearest Discount Tire and Alignment to have your new tires installed.

The tire information may start with a letter or two, which identifies the type of vehicle suited to the tire. The letter ‘P’ means our example tire is suitable for a passenger car. If the tire information does not start with letters, it is probably a car tire.
P225/60R16 98T
The first number indicates the width of the tire. Generally the measurement is shown in millimeters, though four-wheel drive tires sometimes show width in inches. Our example tire has a width of 225 millimeters.
P225/60R16 98T
The second number indicates the height of the tire as a percentage of its width. (This value is often referred to as the ‘aspect’ of the tire.) Our example tire has an aspect of 60, which means the tire’s height is equal to 60% of its width.
P225/60R16 98T
The letter after the height value indicates the construction used within the tire’s casing. Our example tire uses radial (‘R’) construction, while other tires may use belted bias (‘B’) or diagonal bias (‘D’) construction.
P225/60R16 98T
The number after the construction value shows the diameter of the wheel rim suited to the tire. Generally the measurement is shown in inches. Our tire is suited to a 16-inch rim.
P225/60R16 98T
The first number after the tire size is the load index of the tire. By referring to a separate load-index chart, the index value allows us to determine the how much weight the tire can support.
P225/60R16 98T
The final letter provides the speed rating of the tire, which is the maximum speed the tire has been designed to handle. The table below shows the some common speed rating values, where we see that our example tire is designed to handle a maximum speed of 130mph.
