Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What tyre size does the 2018-present BMW 8 Series use?
Common UK factory fitments for the 2018-present BMW 8 Series include 245/45 R19, 275/40 R19, 245/35 R20, 275/35 R20. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.
What speed rating is required for the 2018-present BMW 8 Series?
Performance variants of the BMW 8 Series typically require a Y-rated (300 km/h) or W-rated (270 km/h) tyre. Match or exceed the original speed rating shown on your sidewall — fitting a lower-rated tyre can affect handling and may be illegal on certain models.
Are premium-brand tyres worth it on a BMW 8 Series?
On a BMW 8 Series, premium tyre brands (Michelin, Continental, Bridgestone, Pirelli, Goodyear) typically deliver longer tread life, better wet grip and quieter rolling. The cost difference is usually recouped over the tyre's life.
Did the 2018-present BMW 8 Series come with run-flat tyres?
Many BMW models in this era were supplied with run-flat tyres from the factory. If your car has tyre pressure monitoring and no spare wheel, replacement tyres should typically also be run-flat. Verify on the existing sidewall — look for "RFT", "ROF", "ZP" or similar markings.
What does the chassis code G15 mean for tyre choice?
The G15 chassis code identifies this specific generation of the BMW 8 Series. Tyre fitment guides and parts catalogues use the chassis code to match correct sizes, load indices and speed ratings — useful when ordering online.
