Mercedes-Benz G-Class Tyre Replacement Parts

The G-Class has been built on the W463 platform since 1989, but the heavily revised W463A generation launched in 2018 brought significant changes to wheel and tyre specifications, with the newer car typically running larger wheel diameters and different offset requirements. A tyre from a pre-2018 W463 may share a size designation with a W463A fitment, but this depends entirely on which wheel size your specific car is running, as both generations were offered with multiple rim size options. Check the tyre size printed on your driver's door placard or current tyre sidewall, then confirm with the breaker that the used tyre matches that exact size including speed and load rating.

Trim level alone does not determine tyre fitment on the G-Class — what matters is the wheel size fitted to your specific vehicle, and G63 AMG models are commonly supplied with larger wheels and wider tyre profiles than standard G350d variants. A tyre from a G350d may not match the size needed for a G63 AMG, so always check your existing tyre sidewall for the full size code (e.g. 265/60 R18 or 285/45 R20) before approaching a breaker. Confirm with the breaker that the used tyre matches your exact size, load index, and speed rating against your registration.

A 2015 car falls within the W463 generation while a 2020 car is a W463A, and these two generations can differ in standard wheel sizing, so a direct swap is not guaranteed even if the tyre sizes look similar at a glance. Used tyres are size-specific rather than vehicle-specific, so the key question is whether the tyre size, load index, and speed rating from the 2015 car exactly match what your 2020 car requires. Check your door placard and current tyre sidewall for the required specification, then confirm with the breaker.

The G-Class has been offered with a range of wheel sizes across its production life, meaning tyre sizes vary considerably — common sizes on W463 models include 265/60 R18, while AMG and later W463A variants can run sizes such as 275/50 R20 or 285/45 R22, so there is no single universal G-Class tyre. You must match the tyre size exactly to your vehicle's requirement, including width, aspect ratio, rim diameter, load index, and speed rating, all of which are printed on the tyre sidewall and in your owner's handbook. Never assume any G-Class tyre will fit your car — always verify the full size code before buying from a breaker.

For a standard symmetrical or asymmetric tyre, the NS or OS origin makes no difference to fitment, as tyres are not handed in that sense — however, if the tyre has a directional tread pattern, it must be fitted to a wheel on the correct side so the rotation arrow faces the right way. The key factors are that the size, load rating, speed rating, and tread pattern type (directional or non-directional) all match your requirement. Confirm with the breaker whether the tyre they have is directional or asymmetric, and ensure the size matches your exact specification.

Used tyres from a breaker should have at least 3mm of tread depth (the UK legal minimum is 1.6mm but 3mm is widely recommended for safety), no cracking in the sidewall, no bulges, and no evidence of kerbing damage or repairs. You should also check the tyre's age using the four-digit DOT date code on the sidewall — the last four digits indicate the week and year of manufacture, and tyres over six to ten years old are generally considered past their safe service life regardless of tread. Ask the breaker to confirm the date code and allow you to inspect the tyre before purchase.
