Yeah yeah, like I believe you
I know how mine is driven from time to time and I am sat here wondering how the hell yours is driven to look like that
I tend to take it easy on corners thought to be honest, I see that isn't your style
Reminds me of the many salesmans loan cars I've driven, 1000 mile cars will well scrubbed in side walls
Seriously though, depending on the mileage don you should consider changing both. If anything did go wrong and Audi found there to be a big difference in the tyres, I'd expect they could turn the blame on you as they would tell you to change both at once.
