Understanding Tyre Markings
In order to get you the correct tyre we may need you to review the markings that appear on the sidewall of your tyres.
​
Cars can have different sizes of tyres on the front and rear so if your shopping for a full set then please review both axles of the vehicle.
In addition to the size of tyre we also have to consider the speed rating and whether the vehicle has run flat tyres fitted.
​
For performance vehicles there can also be a homologation specific version of the tyre for your vehicle.
