Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
Are OEM tyres still fitted to new BMW 3 Series cars?
New UK BMW 3 Series 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.
What should BMW 3 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.
What do star/OEM markings mean on BMW 3 Series 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's different about the 2019-present 3 Series compared with other generations?
This is the 2019-present generation of the BMW 3 Series. Earlier and later generations use different platforms, wheel sizes and tyre fitments, so always match your specific year to the correct generation page.
Can I downsize from larger wheels on my BMW 3 Series?
Some trims of the 3 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.
