Audi A4 (2015-present) tyre data — wheel-by-wheel fitments and seasonal options.
About this generation
The 2015-present Audi A4 occupies a specific slot in the Audi lineup, and tyre choice for this generation has to match the wheel and trim ordered from new. The figures on this page reflect UK-market original-equipment fitments.
This generation of the A4 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.
Chassis code: B9. 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 does the chassis code B9 mean for tyre choice?
The B9 chassis code identifies this specific generation of the Audi A4. Tyre fitment guides and parts catalogues use the chassis code to match correct sizes, load indices and speed ratings — useful when ordering online.
Are run-flat tyres needed on the 2015-present Audi A4?
Most 2015-present Audi A4 cars were supplied with conventional tyres and a spare or repair kit. Only fit run-flats if your specific car was originally specified with them and has tyre pressure monitoring.
What do star/OEM markings mean on Audi A4 tyres?
Audi 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 wet grip should I look for on the Audi A4?
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.
The A4 uses 19" or larger wheels — what should I know?
Larger wheels mean lower-profile tyres with shorter sidewalls — that means firmer ride, more pothole sensitivity and shorter tyre life on UK roads. Premium tyres usually repay the extra cost on cars with 19"+ wheels.
