The tyre options for Mercedes CLA35 AMG at Tyres.co.uk include the Michelin Pilot Sport 5 and the Goodyear Eagle F1 SuperSport in 235/40 R18 95Y XL for factory 18-inch-wheel versions. Depending on the model year and specification, Mercedes CLA35 AMG 19-inch fitments differ, so check the registration along with the axle fitment, load index, speed rating, and the XL before purchasing.
Details of the Mercedes CLA35 AMG tyre are available on the tyre sidewall as well as the vehicle's wheel-and-tyre information. The tyre-pressure placard is located inside the fuel filler flap; use this to see the specified pressures for the fitted wheel and tyre combination. Check the registration to confirm the exact fitment before purchasing.
While it is not mandatory to replace all four tyres on the Mercedes CLA35 AMG, the 4MATIC drivetrain does require identical make and model tyres to be fitted on each axle, including matching size and tread patterns. If possible, tyres should be replaced in pairs by axle; when replacing two tyres, UK safety guidance recommends fitting them to the rear axle.
