Look for the numbers on the sidewall of your tire.
The first number you see is the tread width in millimeters.
The second number is the aspect ratio, which represents the height of the sidewall as a percentage of the tread width.
The letter ‘r’ comes next, representing the tire type, which is radial for most vehicles.
The final number is the diameter of the wheel in inches.
