BMW i7 (2022-present) tyre data — wheel-by-wheel fitments and seasonal options.
About this generation
This generation of the i7 runs on 19-inch or larger wheels in some trims, which means short-sidewall tyres that handle precisely but are less forgiving on rough UK roads.
The current-generation BMW i7 (2022-present) is sold in the UK with a small set of factory tyre sizes per trim. Replacement tyres should match the size, load index and speed rating of what came on your specific car.
Chassis code: G70. Use the chassis code to confirm you have the right generation when ordering tyres.

Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What should BMW i7 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.
What do star/OEM markings mean on BMW i7 tyres?
BMW approves specific tyres for many of its models, marked with a star (BMW), MO (Mercedes), AO (Audi), J (Jaguar) or similar. OEM-marked tyres are tuned for that car's suspension and don't always come from the major brand-name fitter as a stock item — they may need to be ordered.
What tyre size does the 2022-present BMW i7 use?
Common UK factory fitments for the 2022-present BMW i7 include 255/50 R19, 255/45 R20, 255/40 R21. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.
Can I downsize from larger wheels on my BMW i7?
Some trims of the i7 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.
Are OEM tyres still fitted to new BMW i7 cars?
New UK BMW i7 cars leave the factory with original-equipment (OEM) tyres specified by BMW. When replacing, you can stay on the same OEM brand or move to an alternative provided the size, load index and speed rating match.
