Hi Gareth, thanks for your interest.
My car has not done many miles over the years because until recently I had a Mazda MX 5 which I used quite a lot ( I have now sold it).
The Audi is not garaged (never has been) tyres are from new, so obviously 5 years old. I didn't take their age into consideration when i assessed the wear (I 'm not the brightest button in the box)'
All in all, I suppose they have served me well and I shouldn't complain.
All tyre walls have cracks so unfortunately, I will need to replace them all.
I may end up getting "Michelin Supremacy's" again, however, I was interested to hear what other Audi owners had to say.
Thanks again for your interest.
Take care.
