Tyres.co.uk offers 215/45 R18 XL versions of the Michelin Primacy 5 93W XL and Pirelli Cinturato All Season SF3 93Y XL tyres for the current 18-inch models of the Mazda Mazda3. Make sure you look at the factory size, load index, and speed rating before purchasing.
The tyre size for the Mazda Mazda3 can be found by looking at the tyre pressure placard located on the driver’s side door frame (when door is opened). This provides the original equipment choice for tyre size, load, and pressure. Please note this along with the owner’s manual and the registration as it can be the case that the wheels or tyres have been modified.
Mazda Mazda3 advice recommends changing all four tyres at the same time. UK front-wheel-drive models do not have a uniquely matching requirement for the drivetrain, but it is best to fit any new set to the rear axle. On International i-ACTIV AWD Mazda3 models, all four must match size, manufacturer, brand, tread type, and pattern.
