I've just won some Team Dynamics Pro race 1.2 on eBay, they're 18x8J E45. My standard S3 speediness are 18x7j ET52 and run 225/40/18 tyres. I was wondered what to go for on the new wheels? I need new tyres anyway so can freely change size. I can only think I could run a 235/35/18 or 225/40/18? Just unsure what to go for.
