Mercedes-Benz GLB Tyre Replacement Parts

The Mercedes-Benz GLB (X247) has been sold as a single generation launched in 2019, so there is no earlier distinct generation to cross-reference against. Tyres are not directly interchangeable between cars in the usual sense — what matters is that the replacement tyre matches your wheel's rim diameter, width, and profile exactly, and that the load and speed ratings meet Mercedes' specification for your GLB variant. Check the tyre size printed on your existing tyre sidewall or in your owner's manual before buying. A breaker can confirm the size coming off the wheel they're selling if you're buying a part-worn or a wheel-and-tyre combination.

Yes, it can — Mercedes specifies different tyre sizes for some GLB variants depending on engine output and whether the car is 4MATIC (four-wheel drive) or front-wheel drive, as heavier or more powerful variants may be approved for wider or larger-diameter fitments. The standard tyre sizes across the GLB range vary, so confirm your exact approved size from the tyre placard on your driver's door jamb or from your owner's manual rather than assuming all GLBs share one size. If you're buying a wheel and tyre together from a breaker, give them your registration so they can match the correct spec.

Trim level alone does not determine tyre fitment in terms of the tyre itself, but AMG Line and higher-specification trims on the GLB are commonly fitted with larger alloy wheels than base Sport models, which means they use a different tyre size — typically a larger rim diameter with a lower profile sidewall. The tyre that fits a 19-inch AMG Line wheel will not fit a 17-inch Sport wheel, so the wheel size is what you need to match, not the trim name as such. Check the rim diameter and tyre size on your existing setup before approaching a breaker.

The GLB X247 covers the 2019-onwards period as one generation, and received a mid-life update around 2023 bringing styling and technology changes but no fundamental change to the wheel and tyre platform. Whether a specific wheel and tyre from a 2019 car fits a 2023 car depends on the rim size and bolt pattern being the same, which you should confirm with the breaker against your registration, as minor running-gear changes are possible across a refresh. The tyre size itself is determined by the wheel, so match that first.

Give the breaker the full tyre size printed on your sidewall — for example 235/50 R19 — along with the load index and speed rating, and mention whether you need it for a front or rear position if your GLB runs different sizes axle to axle (staggered fitment). It is also worth confirming whether your GLB is 4MATIC or front-wheel drive, as this can affect which sizes were originally specced. Always confirm the tyre meets legal UK minimum tread depth requirements (1.6mm) and is free from damage before agreeing to buy.
