Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What should BMW X4 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 X4 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 2014-2018 BMW X4 use?
Common UK factory fitments for the 2014-2018 BMW X4 include 245/50 R18, 245/45 R19, 245/40 R20. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.
Did the 2014-2018 BMW X4 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 wet grip should I look for on the BMW X4?
For UK driving conditions, prioritise an EU tyre label wet-grip rating of A or B. Wet grip directly affects braking distance — the gap between A and E ratings can be more than a car length at 50 mph.
