Second Hand Mercedes-Benz SL Tyre

No — the R129 (1989–2001) and R230 (2001–2012) generations use different wheel sizes and bolt patterns, so tyres that fit one will not directly transfer to the other even if the physical tyre size happened to match. The R230 moved to larger standard rim diameters, meaning a tyre sized for an R129 rim would not seat correctly on an R230 wheel. You need to match the tyre size to your specific wheel, not the generation of the donor car — confirm the exact size moulded on your existing tyre sidewall before contacting a breaker.

The R231 ran from 2012 to 2020, with a mid-life facelift around 2016, but the facelift did not change the wheel fitment specifications, so a tyre of the correct size from a pre-facelift R231 will fit a post-facelift R231 wheel just fine. What matters is that the tyre size — width, aspect ratio, and rim diameter — matches your wheel exactly, which you can read off your existing tyre sidewall or your door-pillar placard. Confirm the exact donor wheel size with the breaker against your registration to be certain.

Yes, it can — larger-engined SL variants such as the SL63 AMG and SL65 AMG were typically fitted with wider tyres and larger-diameter wheels than the standard SL350 or SL400 to handle the extra power and weight. This means a tyre from an SL350 may be a different size to one from an SL63, so you cannot assume any R231-generation SL tyre will fit your car without checking the actual size. Always check the size on your own tyre sidewall and match it exactly, and confirm with the breaker that the donor vehicle's specification aligns with yours.

Trim level in itself does not affect tyre fitment — what matters is the physical tyre size, which is determined by the wheel fitted to the donor car rather than a trim name. That said, different specification levels on the SL (for example, AMG Line or Premium) could have been ordered with different optional wheel sizes, so two cars of the same trim name are not guaranteed to share the same tyre size. Always confirm the exact tyre size printed on the sidewall of the part you are buying matches your own, and check with the breaker against both registrations if in doubt.

Not necessarily — on the R230 generation (2001–2012) for example, the SL500 and SL350 could leave the factory on different wheel and tyre sizes, so you cannot assume they share the same fitment even though they are the same model generation and body. The safest approach is to read the tyre size from your own sidewall and confirm that the breaker's donor tyre matches it exactly before purchasing. Engine displacement and power output do influence running gear specification on the SL range, so always verify the specific size rather than assuming model-family compatibility.

Both years fall within the R230 generation (2001–2012), so the platform is shared, but whether the tyre size is identical depends on which wheel specification each car was fitted with — factory wheel options and running changes mean two R230 SLs of the same engine size built four years apart could carry different tyre sizes. Check the size printed on your existing tyre sidewall and ask the breaker to confirm the exact size on the donor car against your registration before agreeing a purchase. Tyre size is the definitive guide here, not the model year alone.
