Reading Tire Size on a Tire Sidewall

Ever wondered what the letters and numbers on your tires mean? Check out our guide below.
- Tire Type: defines how the tire should be used. For example: "P" means a passenger car tire while "LT" means a light truck tire.Â
- Tire Width: measured in millimeters from sidewall to sidewall. The example tire's width is 215 mm.
- Aspect Ratio: ratio of the tire's cross-section height to its width. The example shows 60, meaning that the height equals 60% of the tire's width.
- Construction: shows how the layers of the tire were put together. "R" stands for radial, meaning layers run radially across the tire. "B" stands for bias construction, meaning the layers run diagonally across the tire.
- Rim Diameter: the width in inches or centimeters of the wheel from one end to another. The diameter of this wheel is 16 inches in our example. Always replace a tire on a rim with another tire of exactly the same rim diameter and suffix letters.
- Load Index: corresponds with the load-carrying capacity of a tire. Most passenger car tire load indexes range from 75 to 100.
- Speed Rating: maximum service speed for a tire.
