Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What tyre size does the 2017-2023 BMW 6 Series use?
Common UK factory fitments for the 2017-2023 BMW 6 Series include 245/50 R18, 245/45 R19, 275/40 R19, 275/35 R20. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.
What does the chassis code G32 mean for tyre choice?
The G32 chassis code identifies this specific generation of the BMW 6 Series. Tyre fitment guides and parts catalogues use the chassis code to match correct sizes, load indices and speed ratings — useful when ordering online.
What should BMW 6 Series drivers know about UK potholes?
UK road conditions are tough on tyres. Check sidewall bulges, cuts and tread depth regularly — especially on the inside edge, which often wears unevenly. A 20p coin gives a quick legal-tread check.
Did the 2017-2023 BMW 6 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.
Can I downsize from larger wheels on my BMW 6 Series?
Some trims of the 6 Series can be downsized to a smaller OEM-approved wheel, which often gives better ride and lower tyre cost. BMW usually publishes approved alternative sizes — check the handbook before changing wheel size.
