Tyres.co.uk offers Michelin Pilot Sport 5 and Goodyear Eagle F1 SuperSport in the sizes 225/40 R18 (front) and 245/35 R18 (rear) for R172 SLK 200, SLK 250 and SLK 350 models with AMG Line wheels. Please confirm registration, load index, speed rating, and XL spec against the vehicle label prior to purchase.
The tyre size for the Mercedes SLK can be found on the tyre sidewall and on the tyre pressure and size label which can be found on the tyre pressure label on the fuel filler door inside the flap on the right. Use this to confirm approved sizes and pressures of the front and rear tyres as some models of the Mercedes SLK will have wheel and tyre staggered fitments.
Each of the Mercedes SLK models is rear wheel drive, and therefore, there is no need to match the 4MATIC rolling circumference, and therefore, as long as any new pair of tyres is fitted to the rear, any staggered size can be fitted. Mercedes does advise to keep matching tyre type and make where possible.
