Alloy Wheel Diameter

A quick and easy way to find out the size of your wheel is to check the radius (R) of your tyre e.g. 205/45R15 tyre would indicate you have R15 = 15 inch tyre on your car.  As a result of your tyre size, the diameter of your alloy wheel will be 15" also. 

Alloy Wheel Width

To find out the width of your alloy wheel, you will need to check on the alloy wheel itself.

On every alloy wheel the size will be stamped into the alloy wheel, this stamp can be on the outside but is usually stamped on the inside of the alloy wheel on the back of the spokes.

For example, the stamp may read 15 x 7, 7 x 15, 15x7JJ etc. The second value in 17x7 indicated the width of your alloy wheel, in this case the wheel is 7 inches wide (with a diameter of 17 inches).
