Use the registration search for the most accurate match, or check the tyre sidewall for the size (for example 225/45 R17). You can also confirm the approved size on the driver door sticker or in the handbook.

Only use manufacturer-approved sizes and make sure the load index and speed rating meet or exceed the original specification. If you change sizes, check clearance, handling and your insurance requirements before fitting.

You select a nearby garage and an appointment slot, then the tyres are delivered to that fitter for your visit. The garage fits and balances the tyres, and can dispose of the old ones (fees and inclusions vary by fitter).

The UK legal minimum is 1.6mm across the central three-quarters of the tread around the full circumference. Many drivers replace earlier (around 3mm) for better wet grip and shorter stopping distances.

All-season tyres can be a strong option if you want one set year-round, especially for mixed temperatures and frequent wet roads. If you drive mainly in warmer months or do high motorway mileage, a summer tyre may suit you better, while winter tyres are best for regular cold or icy conditions.
