At Tyres.co.uk for Mazda CX-7, tyre options include the Michelin Primacy 4 and Dunlop Sport Maxx RT in 235/55 R19 101V for UK 2.3 DISI petrol and 2.2 MZR-CD models with 19 inch wheels. Please verify the door-placard specification against the registration. Note that the 2.2 diesel variants had an 18 inch wheel option as well.
Information regarding the tyres of the Mazda CX-7 can be found on the tyre-pressure placard, which can be found either on the driver's-side B-pillar or, on some versions, on the edge of the driver's door frame. You can check the approved specifications for the tyres, load and speed ratings, along with the recommended cold inflation pressures, by opening the driver's door.
For all UK models of the Mazda CX-7, the manufacturer recommends that the tyres are the same size and type. Additionally, Mazda CX-7 AWD models have all-wheel drive, therefore it is advised that all four tyres must be replaced at the same time to ensure proper function. If you have to replace only two tyres, in line with UK safety guidance, only put the new set on the back axle.
