Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
Can I downsize from larger wheels on my Audi A4?
Some trims of the A4 can be downsized to a smaller OEM-approved wheel, which often gives better ride and lower tyre cost. Audi usually publishes approved alternative sizes — check the handbook before changing wheel size.
Where should I check the original tyre size for my Audi A4?
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.
Why does the same A4 generation list multiple tyre sizes?
Within one generation of the A4, Audi offered different wheel sizes by trim and option pack. A Sport or M Sport variant might use wider, lower-profile tyres than the entry trim. Always go by the actual wheel fitted to your car.
Are run-flat tyres needed on the 2000-2006 Audi A4?
Most 2000-2006 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 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.
