 As long as you have tyres that are with the same or better rating than recommended in the manual, and of the exact size as mentioned for the stock car, I dont see how any manufacturer can make your warranty void on related components. This is ridiculous. What if your tyre gets a cut? Can you not purchase one from the after market ever within the warranty period? And what if you go for an extension on the warranty for four years? Perhaps one of the members can enlighten me on this. P.S. Can this be termed anti-competitive behaviour?

You make excellent points latentpotential, but Audi goes as far as associating the serial number of the tyres that come with the car, and, if there is a serial number mismatch, they won't honour warranty. Apparently, according to the service advisor, the only way to update that serial number is to buy new tyres from Audi, at their exhorbitant rates. I had planned on separately importing one tyre myself (since the tyre dealers I went to didn't stock that make and model of tyre), but the serial number will then mismatch.

Please see this link from Michelin in the UK: http://www.michelin.co.uk/tyres/brands/audi/a0 You can select which exact model of the A0 you have, including engine type, rim size and model year, and you will end up with at least two recommendations of tyres from Michelin. I am sure it is similar with other vendors, even if they dont have such a fancy online setup for the user to choose a tyre from. I think it is time to give such vendors and their preposterous practices Hell.
