Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
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.
What's different about the 2015-present A4 compared with other generations?
This is the 2015-present generation of the Audi A4. Earlier and later generations use different platforms, wheel sizes and tyre fitments, so always match your specific year to the correct generation page.
What tyre size does the 2015-present Audi A4 use?
Common UK factory fitments for the 2015-present Audi A4 include 205/60 R16, 225/50 R17, 245/40 R18, 245/35 R19. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.
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.
What should Audi A4 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.
