At Tyres.co.uk, tyre choices for the Mercedes X-Class include the Goodyear Eagle F1 Asymmetric SUV AT, and Michelin Primacy 5, both of which are available in 255/60 R18, which is an original equipment size for the X-Class models with 18-inch wheels. Prior to purchasing, ensure to verify the required load index, speed rating, and XL specification from the B-pillar placard and registration.
To find the tyre size for the Mercedes X-Class, look for the tyre-pressure placard located on the driver's-side B-pillar (visible upon opening the driver's door). You can also find the tyre size imprinted on the sidewall of the tyres, and the placard displays the recommended pressures for varying loads and operating conditions.
You don't need to replace all four Mercedes X-Class tyres at the same time. You can get two tyres replaced as long as the tyres on the same axle are identical, and the new pair are fitted to the rear axle. For the X350d with permanent four-wheel drive, all four tyres must be the same. For the selectable four-wheel drive versions, matching tyres are also required on each axle.
