Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What should Audi Q8 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.
Can I downsize from larger wheels on my Audi Q8?
Some trims of the Q8 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 Q8?
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's different about the 2018-present Q8 compared with other generations?
This is the 2018-present generation of the Audi Q8. Earlier and later generations use different platforms, wheel sizes and tyre fitments, so always match your specific year to the correct generation page.
What wet grip should I look for on the Audi Q8?
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.
