How to Read Your Tyre Size

Your tyre size specifications are outlined by the various numbers and letters located on the sidewalls of your tyres.

At first glance, you may just see a jumble of numbers and letters on your tyre sidewall that seems completely meaningless. But understanding these bunch of numbers and letters will make life a whole lot easier when it comes to replacing your tyres. Finding your tyre size is more straightforward than you may think, once you break the letters and numbers down into sections.

If you need a new tyre, you can find your tyres specification on the sidewall. Each number has a different meaning in this order:
