How to Read Your Tire Size

Your tire size is printed on the sidewall in a format such as 225/60R17.

What each number means

  • 225 is the tire width in millimetres.
  • 60 is the sidewall height as a percentage of the tire width.
  • R means radial construction.
  • 17 is the wheel diameter in inches.

Match all three numbers before ordering. If you are unsure, call 403-707-3064 and Westline Automotive will help confirm the correct size.
