It depends on the Yaris year and trim. Use the registration search for an exact match, or check the tyre sidewall for a size like 175/65 R15, 185/60 R15 or 195/50 R16 (examples only).
It is legal if the tyres meet the correct size and rating, but it is best practice to fit the same tyre model on the same axle to keep braking and handling consistent, especially in wet UK conditions.
UK law requires at least 1.6mm across the central three-quarters of the tyre and around the full circumference. Many drivers replace earlier (around 3mm) for better wet grip.
All-season tyres can be a strong option for typical UK weather, offering better cold and wet performance than summer tyres. If you regularly drive in snow or very cold areas, winter tyres may be worth considering.
Select your tyres, then pick a local fitting garage and appointment slot at checkout. The tyres are delivered to the garage, and you attend for fitting (bring your locking wheel nut if you have one).
