Registration lookups usually match the correct factory fitment, but it is worth double-checking the tyre size and load and speed ratings on your current tyres, especially if your wheels have been changed.
Look at the tyre sidewall for a code like 215/60 R16, then enter that size and make sure the replacement tyres match the same load index and speed rating (or higher, where permitted).
All-season tyres can suit many UK drivers by balancing wet grip and cooler-temperature performance year-round, while winter tyres can be better in frequent snow or near-freezing conditions.
After selecting tyres, you pick a nearby garage, choose a date and time, and the tyres are delivered there for fitting so you can turn up for your appointment without carrying tyres yourself.
The UK legal minimum is 1.6mm across the central three-quarters of the tread around the full circumference, but many drivers replace earlier for better wet-weather braking and reduced aquaplaning risk.
