Used BMW i7 Tyre

The BMW i7 launched in 2023 as the first generation (G70 platform) and has continued in that same generation without a significant facelift through to 2024-2025, so tyre sizes are consistent across those years provided the wheel specification matches. The i7 uses staggered fitments on some variants (for example 245/45 R21 front and 275/40 R21 rear on xDrive60 models), so you must match the exact size, load rating, and speed rating rather than simply the year. Always confirm the tyre size on your door-jamb sticker or sidewall before buying from a breaker.

Trim level does not change whether a tyre physically fits, but the three variants can be supplied with different factory wheel and tyre size options, so fitment depends on the actual tyre size rather than the trim name itself. The M70 xDrive in particular may leave the factory on larger or different-spec tyres compared with the eDrive50, so check the exact size on your tyre sidewall or door placard first. Your breaker will need that size — not just the trim name — to supply a matching used tyre.

The BMW i7 does fit conventional (though often run-flat specified) road tyres on standard alloy wheels, so it is a genuine used-tyre search. Many i7s left the factory with BMW-approved run-flat tyres, meaning they are marked RFT or RF on the sidewall, and if your car was set up without a spare wheel on that basis you should source a matching run-flat replacement rather than a standard tyre. Confirm with your breaker whether the tyre they have is run-flat or standard before purchasing.

The G70 i7 has been in production since 2023 and no major mid-generation wheel or tyre specification change is publicly confirmed, so tyres of the same size should be interchangeable within the generation. However, BMW occasionally introduces running changes to approved tyre specifications during a model year, so confirm with the breaker that the size, load index, and speed rating all match your door-sticker specification exactly. Never rely on year alone — the size printed on the tyre sidewall is the definitive check.

Both the xDrive60 and the M70 xDrive are G70-generation i7s, but the M70 is a higher-powered variant that may be factory-fitted with a different tyre size or load rating to suit its greater performance. If both cars share the identical tyre size, load index, and speed rating the tyre will physically fit, but you should verify this against your own door-placard data before buying from a breaker. Trim alone is not a reliable guide here — the numbers on the sidewall are what matter.

Give the breaker the exact tyre size from your sidewall or door-jamb placard (for example 245/45 R21 100Y RFT), the vehicle registration number, and whether the car is eDrive50, xDrive60, or M70 xDrive, as this helps them cross-reference the correct specification. Also confirm whether your car runs run-flat tyres, since mixing run-flat and standard tyres on the same axle is not recommended and may affect your vehicle's safety systems. The more precise you can be, the better the chance of a safe and correct match from the breaker.
