This alphanumeric code contains essential information about the tire’s dimensions, load capacity, speed rating, and other specifications. Properly sized and maintained tires are vital for ensuring safe and efficient driving.
Measurement
The tire size of a car is typically measured in inches. The diameter is measured in inches. The width is measured in inches. The aspect ratio is expressed as a percentage.
Measuring a tire’s size can be done by examining the numbers and letters on the sidewall. This code typically looks like this: P215/65R16. Here’s how to interpret and measure it:
