On Tyres.co.uk for the Ford Grand C-MAX, the tyre options include the Michelin Primacy 5 XL and Goodyear EfficientGrip Performance 2; both are offered in the size 215/55 R16 97W for 1.0-litre and 1.6-litre EcoBoost, as well as 1.6-litre and 2.0-litre TDCi models with 16-inch wheels. Refer to the B-pillar label for the specification that is specific to your registration.
Details regarding the tyre size and pressures for the Ford Grand C-MAX can be found on the tyre-inflation label located on the B-pillar of the driver's door opening. This label indicates the approved factory specifications for the tyre and the cold pressure levels for the vehicle. Although the tyre sidewall also shows its fitted size, the B-pillar label is the definitive answer.
The Ford Grand C-MAX is a front-wheel drive vehicle, meaning that all four tyres do not need to be replaced, as there is no all-wheel drive version that would require closely matched tyres across both axles. As a general rule, tyres should be replaced in pairs on the same axle, with the same size and type of tyre on each axle. When installing two new tyres, they should be placed on the rear axle.
