James,
The weight we need to know is the weight of the tire and wheel combined.  If the 15" wheel weighs more and the 15" tire weighs less then every thing may be even.  If the 15" tire weighs more than the 185R14 then the unsprung weight would increase even more.
Has anybody checked this out.  Also does anyone know how much the Audi 5000 15" wheel weighs?
Thanks,
George
