For 2013-2016 Mercedes CLA45 AMG models, Tyres.co.uk has Pirelli P Zero and Goodyear Eagle F1 SuperSport in 235/40 R18 95Y XL that match the factory 18-inch wheels. Please note that for CLA 45 models post-2016, there are differences in wheel and tyre specifications. So, ensure the registration and the fuel-filler-flap table before purchasing.
The approved tyre sizes for the Mercedes CLA45 AMG can be found in the tyre-pressure chart on the inside of the fuel-filler flap. The chart states approved factory sizes. The actual tyre information can be found in the Tyre and Loading Information placard on the driver side B-pillar. This is accessible with the front door opened.
A CLA45 AMG does not necessarily need all four tyres replaced at once, but its 4MATIC drivetrain means the four should be matched, and of the same brand where possible. According to the UK's safety guidelines, where two new tyres are fitted, they must be placed on the rear axle.
