Can’t Find Your Tyre Size?

Your tyre size is shown on the wall of the tyre (e.g. 205/55-16). 

Please check your owners handbook to ensure snow chain suitability.

Here are a few suggestions to help:

1. Verify you have noted the numbers correctly from the tyre.

2. If you have navigated to a specific category or product page, only tyre sizes covered by that product/category will be shown. To search across all our ranges, please use the tyre size box on the homepage.

3. Call or email us (we will investigate and advise), if it is just an unusual size we may still have options for you.

Fitting a manually tensioned snow chain

Please check vehicle manufacturer’s handbook for specific recommendations regarding the use and fitting of snow chains. We recommend a trial fitting once you receive your chains to check they fit and that there are no clearance issues. We keep our fitting and clearance listings as up to date as possible, but as there are so many variations of vehicle and tyre size combinations it is the user’s responsibility to ensure the chain is suitable for their vehicle. Please note chains cannot be driven on non-snow covered roads and therefore it is not possible to trial fit a K-Summit.

Please see our fitting videos for guidance on checking clearance. Our experienced sales team are happy to help if you have any questions regarding the suitability of chains for your vehicle.
