Tyres.co.uk lists Michelin Primacy 5 and Continental PremiumContact 6 in 235/55 R17 103W XL for the Mercedes V-Class 2021 4MATIC model with 17-inch factory wheels. Please note, prior to placing an order, the exact specifications (size, load, speed and XL rating) should be confirmed along with the vehicle registration.
The Mercedes V-Class tyre size information can be found on the vehicle's tyre pressure placard located on the fuel filler flap. The following table lists approved combinations of wheels and tyres and their corresponding tyre pressures. In the handbook and on the sidewall of the tyres, the factory wheel options will show the different load index and speed symbol ratings. These should be compared.
The Mercedes V-Class does not require the same size or tread pattern on both axles, but the tyres should match across each axle. Mercedes also recommends the same tyre brand and design, and this applies to 4MATIC versions front and rear. When replacing two tyres, install the new tyres on the rear wheels.
