Used Mercedes-Benz GLA Tyre

These are two different generations — the first-generation GLA (X156) ran from 2014 to 2019, while the second-generation GLA (H247) launched in 2020 — and the two generations use different wheel and tyre sizes, so they are not directly interchangeable. Your specific tyre size is determined by your wheel rim width and diameter, which can differ even within a generation depending on the trim and optional wheel packages fitted. Always confirm the exact tyre size marked on your tyre sidewall (e.g. 225/50 R18) and check the rim size on any used wheel before buying.

Engine size can influence tyre fitment indirectly, because more powerful GLA variants — such as the GLA 250 or AMG Line models — were sometimes fitted with larger diameter alloys and therefore different tyre sizes than lower-powered variants like the GLA 180 or 200. The key figure is the tyre size printed on your sidewall, not the engine alone, so always cross-reference that with any used tyre or wheel you are considering. A breaker can confirm what size was standard for your specific variant against your registration.

Trim level itself does not change the fundamental tyre specification, but Mercedes-Benz GLA trim levels such as Sport and AMG Line were often sold with different optional alloy wheel sizes, which means the tyre profile and width could differ between two cars of the same year. Colour, interior spec, and other cosmetic differences between trims have no bearing on tyre fitment whatsoever. Check the tyre size on your own sidewall and match it exactly, regardless of trim name.

The first-generation GLA (X156, 2014–2019) and second-generation GLA (H247, 2020 onwards) are built on different platforms and used different wheel sizes as standard, so tyres from the earlier car will not necessarily suit the later one. Whether a specific size happens to cross over depends entirely on whether both cars have the same rim diameter and width, which varies with optional wheel packages. Confirm your exact rim and tyre size with a breaker against your registration before purchasing.

The first-generation GLA (X156) received a facelift in 2017 but remained on the same basic platform throughout its 2014–2019 lifespan, so tyre sizes were broadly consistent across that generation. However, the facelift brought updated trim and wheel options that could mean a different alloy diameter or width was fitted, affecting the correct tyre size. Match the tyre size on your sidewall exactly and check with a breaker that the used tyre corresponds to your specific wheel setup.

Tyres are a consumable item and UK breakers typically do not sell used tyres as standalone parts, since worn or aged rubber is considered a safety-critical item and most dismantlers strip tyres from alloys before selling the wheel. If you need a tyre, a fast-fit centre or tyre retailer is the appropriate route; if you need a complete used alloy wheel with a tyre, some breakers will supply that as a package but the tyre condition should be carefully checked. For a used alloy wheel alone, a breaker quoting against your registration is a sensible starting point.
