OK Thanks
I am not fixating, I am just curious
My thought process is that looking at the wifes A2 (15" pepperpots with 185/60/15's) the wheel and tyre have a fairly straight profile, kind of like when people use pizza trays to improve the aero.. Mine seems to look a bit more like a donut so was curious if I would be better off with a wider rim to straighten up the sidewall a bit. Swapping wheels is relatively cheap as they never fail to sell on Ebay
