Mercedes G-Class tyre options at Tyres.co.uk include the Michelin CrossClimate SUV and Pirelli Scorpion All Season SF3 in 265/60 R18 114V XL, a factory-approved fitment for current G 450 d, G 500 and G 580 models. Confirm the exact wheel option, load index, speed rating and XL specification against the registration before ordering.
Mercedes G-Class tyre sizes and pressure guidelines are located on the tyre-pressure table inside the fuel-filler flap. The table is specific to your vehicle, so compare it to the markings on the fitted tyre or the Certificate of Conformity, especially if optional wheel packages have been fitted.
Mercedes G-Class vehicles do not always require four new tyres, however, due to their four wheel drive systems, the tread patterns, size and types of tyres need to match and be identical across all four wheels. Therefore, all four tyres must be replaced if any of the tyres would cause a significant difference in rolling circumference. If only two tyres need replacing, and a tread pattern/size match is possible, the new tyres should be fitted to the rear axle in accordance with UK tyre safety guidelines.
