For the W166 ML 250 BlueTEC 4MATIC and ML 350 BlueTEC 4MATIC models with 18-inch wheels at Tyres.co.uk for the Mercedes M-Class, tyre options include Michelin Pilot Sport 4 SUV and Continental PremiumContact 6 in 255/55 R18 109Y XL. Check the registration's load index, speed rating, and specifications before purchasing.
The tyre sizes for the Mercedes M-Class can be found printed on the sidewall of each tyre fitted. The vehicle's Tyre and Loading Information can also be found on the driver's side B-pillar (accessible by swinging open the front door), while the tables for the tyre pressures can be found on the inside of the fuel flap. To find the approved specifications, check the handbook.
It is not necessary for all four tyres to be replaced on the Mercedes M-Class. Mercedes stipulates the same specifications for tyres and wheels; 4MATIC variants must use the approved front-to-rear rolling circumferences, even with a factory stagger. In accordance with UK tyre safety guidance, if replacing a pair of tyres, the new tyres should be fitted to the rear axle.
