When we talk about the size of an alloy wheel, we are usually referring to the diameter, and this is normally measured in inches. The size of alloy wheels varies from around 10” right the way up to 23”, but not all wheels will fit all cars! Use our vehicle selector to view the range of wheels that are suitable for your car or van. In most cases a small range of sizes will be available - once you’ve selected your vehicle you will be able to filter by size or alternatively simply select a wheel from the results shown and the available sizes will be displayed.
