Check the tyre sidewall for a size like 195/60 R15, or look on the driver door jamb sticker and in the handbook. You can also use registration search, then confirm the size matches what is fitted to your car.

It is usually accurate, but some B-Max trims and wheel options can have more than one approved size. If you are offered multiple fitments, verify against the tyre sidewall or the vehicle placard before buying.

In the UK it is generally legal to mix brands if the tyres are the same size and meet the required load and speed ratings, but it is best to match tyres on the same axle. Avoid mixing summer with winter or all-season on the same axle for consistent grip and handling.

The legal minimum is 1.6mm across the central three quarters of the tread, around the full circumference. Many drivers replace earlier (often around 3mm) to maintain stronger wet-weather braking and reduce aquaplaning risk.

After choosing tyres, pick a nearby garage and select a date and time slot at checkout. On the day, bring your locking wheel nut key if you have one, and ask the fitter to check pressures and valves - wheel alignment may be recommended if your old tyres show uneven wear.
