Find my
tyre size
Your tyre size is printed on the side of every tyre, and the recommended size and pressure is on a placard inside the driver’s door. Here’s how to read it — or just send us your rego and we’ll work it out.
Two places to find it
On the tyre: look at the sidewall for a code like 205/55 R16 91V. Every tyre on the car should show it — check the front and rear, as some cars use different sizes on each axle.
On the car: open the driver’s door and look for the tyre placard on the door frame. It lists the original tyre sizes and the recommended pressures for your car.

205 is the tyre width in millimetres, 55 is the sidewall height as a percentage of the width, R means radial, 16 is the wheel diameter in inches, 91 is the load index and V is the speed rating.
