Can I change the size of tyre I am ordering?
Changing your tyre size
You can change your tyre size, but it is important to stay within the sizes approved by your vehicle manufacturer. Fitting a non-approved size can create safety and legal issues that are best avoided.
Why correct sizing matters
Your vehicle's suspension, braking system, speedometer and electronic safety features are all calibrated around specific tyre dimensions. Fitting an incorrect size can affect:
- Handling and braking performance
- Speedometer and odometer accuracy
- Your car insurance validity
- MOT compliance
- The operation of ABS and traction control systems
How to check approved sizes
When you search by registration on Tyres.co.uk, we may show multiple tyre sizes. These are the sizes approved for your vehicle and usually correspond to different wheel sizes, for example 16 inch, 17 inch or 18 inch options. You can safely choose any of them, as long as they match the wheels currently fitted on your car.
What if I want a non-standard size?
If you want to fit a size that does not appear in the registration search results, we would recommend checking with a tyre specialist or your vehicle manufacturer before ordering. An incorrect size could compromise safety and may cause your car to fail its MOT.
