Changing wheel diameter
Changing wheel diameter usually means changing tyre sidewall height to keep the overall rolling diameter close to the original setup.
Upsizing wheels can reduce tyre sidewall height. Downsizing wheels can increase sidewall height.
Checks before changing wheel size
- Brake clearance
- Wheel width and offset
- Tyre load index and speed rating
- Rolling diameter difference
- Arch and suspension clearance
- Insurance and legal requirements
Always verify fitment with your vehicle manufacturer, tyre retailer or wheel specialist before buying tyres or wheels.
