Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What speed rating is required for the 2008-2016 Audi S4?
Performance variants of the Audi S4 typically require a Y-rated (300 km/h) or W-rated (270 km/h) tyre. Match or exceed the original speed rating shown on your sidewall — fitting a lower-rated tyre can affect handling and may be illegal on certain models.
What does the chassis code B8 mean for tyre choice?
The B8 chassis code identifies this specific generation of the Audi S4. Tyre fitment guides and parts catalogues use the chassis code to match correct sizes, load indices and speed ratings — useful when ordering online.
What should Audi S4 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.
The S4 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.
What do star/OEM markings mean on Audi S4 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.
