Second Hand Mercedes-Benz B-Class Tyre

Tyres are not body-specific parts — what matters is that the tyre size (width, profile, and rim diameter) matches your car's specification, not the model year. The W246 B-Class ran from 2011 to 2018 with a facelift in 2014, but tyre sizes within that generation can still vary depending on the trim level and wheel fitment the car left the factory with. Check the placard inside your driver's door or your current tyre sidewall for the exact size (e.g. 205/55 R16) before buying. Never assume a tyre fits based on year alone — always match the size marking exactly.

The W245 (2005–2011) and the W246 (2011–2018) are different generations of B-Class and were built on different platforms, so their wheel and tyre specifications are not automatically compatible. The W246 generally uses larger rim diameters on many trim levels, meaning the tyre sizes differ between generations. Always check the exact tyre size printed on the sidewall of your current tyre and match it precisely — do not assume cross-generation compatibility. Confirm with the breaker that the size on the used tyre matches your car's requirement.

Trim level itself does not determine tyre fitment — what matters is the wheel rim size fitted to your specific car, which can vary even within the same trim if different alloy or steel wheel packages were specified. On the W246 B-Class, SE, Sport, and AMG Line trims (among others) were available, and cars in higher or sportier trims sometimes left the factory on larger rims with correspondingly different tyre profiles. The safest approach is to read the tyre size off your existing tyre or check your door placard, as two cars of the same trim can have different wheel sizes depending on factory options. Trim name alone is not a reliable guide to tyre size.

Engine size can influence tyre fitment indirectly, because more powerful variants of the W246 B-Class were sometimes offered with larger wheels as standard or as an option, which changes the required tyre profile. However, the direct factor is always the actual rim diameter and width fitted to your car rather than the engine code itself. Check your tyre sidewall or door placard for the exact size rather than relying on engine size as a proxy. Confirm with the breaker that the used tyre's size matches yours exactly before purchasing.

Used tyres are available from breakers and dismantlers, but you must ensure the size on the tyre sidewall (width, aspect ratio, and rim diameter) exactly matches your car's specified size — even a seemingly small difference can affect handling, speedometer accuracy, and MOT compliance. Beyond size, check that the used tyre has adequate tread depth (the UK legal minimum is 1.6mm across the central three-quarters of the tread), no sidewall damage, and no signs of age cracking. It is also worth noting whether the tyre is a run-flat, as the W246 B-Class was offered with run-flat tyres on some variants, and mixing run-flat and standard tyres is not recommended. Always inspect the tyre in person or ask the breaker for detailed photos and condition information before buying.

The W246 B-Class facelift arrived in 2014 and brought styling updates but the underlying platform and wheel fitment options remained broadly consistent across the generation. This means a tyre from a pre-facelift W246 (2011–2014) could well be the same size as one from a post-facelift car — but only if the rim diameter and tyre dimensions match exactly, which depends on which wheels each individual car was fitted with. Whether a specific used tyre crosses the facelift boundary safely is something you should confirm with the breaker against your registration and the exact size on your tyre sidewall. Do not assume compatibility based on generation alone.
