Tyres.co.uk offers seal units for Mercedes GLC63 AMG. These include Michelin Pilot Sport 4 SUV and front Pirelli PZ4 265/45 R20 and rear 295/40 R20 for the GLC 63S 4MATIC+ model, equipped with factory 20-inch wheels. Check vehicle registration and wheel fitment before purchase.
The specifics on the correct pressures and tyre fitments for the factory wheel package along with some other specs can be found on the tyre placard behind the fuel-filler flap in the Mercedes GLC63 AMG. You will need the latest and most current version of the handbook, check the tyres, and compare all to the placard and the registration.
The Mercedes GLC63 AMG doesn't legally require all four seals to be replaced. However, all GLC 63 variants require same tyres front to rear, of same make, and approximation of same age. Due to its set-up, front-to-rear rotation is not possible, and, therefore, when a new set of seals is fitted, the matching set should be fitted to the rear axle.
