Tyres.co.uk lists tyre options for the Toyota GR Yaris such as the Goodyear Eagle F1 SuperSport and Michelin Pilot Sport 4 S in 225/40 ZR18 92Y XL for the standard factory 18-inch fitment. Please check the driver-door placard and registration details for the specific load index, speed rating, and specifications prior to ordering.
Information regarding the tyre sizes for the Toyota GR Yaris can be found on the driver-side door recess tyre-pressure placard, which can be accessed with the driver's door open. The placard displays the approved tyre specifications, as well as the cold pressure values and should be compared to the tyre sidewall and the registration prior to selecting replacement tyres.
Toyota GR Yaris models don't need to have four new tyres put on, but since every UK model has GR-FOUR all-wheel drive, Toyota states that you must have matching sizes, brands, tread patterns, and closely matched tread wear. If you have a compatible matching pair, then in accordance with UK tyre safety guidance, you should put the new tyres on the rear axle.
