Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What's the legal tread depth for a Audi A6 in the UK?
The UK legal minimum tread depth is 1.6mm across the central three-quarters of the tyre. Many tyre safety bodies recommend replacing at 3mm for better wet weather safety on the Audi A6.
Where do I find the load index for Audi A6 tyres?
Load index appears at the end of the tyre size, just before the speed rating — e.g. 91V means load index 91, speed V. Match or exceed the original load index shown on the door placard of your Audi A6.
Why does the Audi A6 have different tyre sizes by year?
The Audi A6 has had 14 UK-market generations. Each generation uses a different platform and wheel options, so tyre sizes are not interchangeable across the model's history. Pick the year-correct generation page for accurate fitment data.
Do estate and saloon A6 variants share the same tyres?
Saloon and estate variants of the Audi A6 typically share wheel sizes, but estate trims sometimes carry a higher load index for cargo capacity. Check the placard on your specific car.
What pressure should the Audi A6 run?
The correct pressure for your Audi A6 is on the placard inside the driver's door frame and in the handbook — not on the tyre itself. Pressure varies by load and trim. Check cold once a month.
