Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What wet grip should I look for on the Audi A8?
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.
Where should I check the original tyre size for my Audi A8?
Look in three places: (1) the sidewall of the existing tyre, (2) the placard inside the driver's door frame, and (3) the vehicle handbook. The driver's door placard is the official OEM specification, and the sidewall confirms what's fitted now.
What do star/OEM markings mean on Audi A8 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 tyre size does the 2002-2010 Audi A8 use?
Common UK factory fitments for the 2002-2010 Audi A8 include 235/55 R17, 235/50 R18, 255/45 R18, 255/40 R19. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.
The A8 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.
