During my lunch break I've just been outside fannying about with wheels and spacers. Purely as a cosmetic test I wanted to make sure I didn't still have any hankerings for my old RS4 19" reps before I sell them off. However whilst I was at it I decided to weigh: 1) RS4 replica 19" with 235/35/19 Uniroyal Rainsport 2 tyre (8J) with more balancing weights than a peck deck. 2) A pristine hollowformed BBS branded Audi 18" Rotor BE 18" with a 225/40/18 Bridgestone Potenza RE050 tyre on it (7.5J) Both tyres have 6-7mm tread depth. One of the wheels weighs 23.9kgs, the other one weighs 22.6kgs. So the question I have for you all given the information above, is which is heaviest!!!
