You want flush with fender best is offset ET35, use 195/50R15. 195/55R15 might scrub the fenders....Hmm actually I think that makes sense, if I'm gonna end up paying the same price as UHP tyres, might as well get UHP tyres.
So now the question is RIMs.
If I'm going for 185/55-15 (1.3%), then the rims should be around 5.5jj - 6jj, then what would the min/max Offset be? because I want to make the rims as flush as possible with the fender.
