Check the tyre size on the sidewall of your current tyres, or look at the vehicle placard (often inside the driver’s door area) and the owner’s handbook. BMW 4 Series tyre sizes can differ by trim level, wheel size and optional packages, so using your registration or confirming the size is the best way to match the correct fitment.
Many BMW 4 Series models leave the factory on runflat tyres, especially where there is no spare wheel. You may be able to switch to non-runflat tyres, but it is important to fit a full set with the correct rating, consider carrying a mobility kit, and avoid mixing runflat and non-runflat tyres on the same car.
In the UK the legal minimum tread depth is 1.6mm across the central three-quarters of the tyre, around the full circumference. For a BMW 4 Series, many drivers replace tyres earlier to maintain strong wet braking and stability, especially if you notice uneven wear, reduced grip, or the tread is approaching the wear indicators.
It is best to fit matching tyres on the same axle (same brand, model and tread pattern) to keep handling predictable, particularly on higher-powered variants. Avoid mixing different tyre types such as runflat and non-runflat, and always match the correct size and ratings for your BMW 4 Series.
After finding tyres that fit your BMW 4 Series, you choose a local fitting garage and select an appointment time. The tyres are sent to the garage for your booking, and you simply arrive for fitting. You can also consider adding wheel alignment if you have uneven tyre wear or your steering feels off-centre.
