Where Can I Find My Tire Size?

- Glove box door
- Gas tank hatch
- Driver’s side door jamb
- The sidewall of your current tires
How Do You Read a Tire Size?
Tire sizes are written in a sequence of measurements, starting with a letter. Then, it adds the width, aspect ratio, construction, rim diameter, load index, and speed rating. An example of a tire size would be: P245/45R19 98S.
Initial Letter
Most tires start with a ‘P’, which is P-metric and indicates it’s a passenger car. If it starts with ‘LT’, it’s LT-metric and a light truck. Additionally, it could have a ‘T’ (temporary) or ‘ST’ (special trailer).
Width
This is the measurement of your tire’s width, measured in millimeters. In this case, the width would be 245 millimeters.
Aspect Ratio
The aspect ratio is expressed as a percentage. So, “45” would be 45%. It’s calculated by dividing your tire’s sidewall height by its width.
Construction
The next letter indicates the tire’s construction. It’s either ‘R’ for radial or ‘D’ for diagonal or bias ply.
Rim Diameter
This is a measurement of your rim’s diameter, in inches. In this case, it would be 19 inches.
Load Index
The load index tells you how much weight your tires can safely carry, in pounds. Rather than a specific number, it refers to the vehicle’s load capacity.
Speed Rating
The final letter is your speed rating, which signals the maximum speed that a tire can withstand.
