Currently, Tyres.co.uk offers factory Pirelli P Zero MC1, P Zero Corsa MC1, and Bridgestone Potenza Sport in 245/35 ZR19 front, and 305/30 ZR20 rear, for the McLaren 720S. For these options, you would choose XL tyres, which are rated at 93(Y) for the front, and 103(Y) for the rear, on the MC-marked Pirelli specification where applicable.
There is a placard on the inside of the McLaren 720S’s fuel filler cap that gives the details for the size and pressure of the tyres. Some versions of the car may have the placard in a more convenient location, which is at the bottom of the driver side door opening. If you are trying to locate the size of the tyres, you will find it along the sidewall of the tyres, as well as on the McLaren 720S placard and registration.
McLaren 720S do not necessitate all four tyres in order to be replaced. Since the road-going versions of the 720S are rear wheel drive, there is no all-wheel drive matching. Tyres should be replaced as matched pairs in each axle. In accordance with UK safety standards, the pair is to be installed on the rear axle when a new pair is fitted/installed. The factory track-oriented option should also be replaced in axle sets.
