These wheels replaced the stock 17x7.5J on my Audi Gen 1 TT. They are 18x9, offset ET 31/32, using 255/35R18 tires which are the same diameter as stock. The tires are worn out and only to check fit on your car - including VW Golf, etc. They looked great and worked well on my TT, which I have sold. These are expensive wheels (go to the Forgeline site) but have been used, and the outer ring of the 3-piece design is satin on 3 of them and chrome on one - although I didn't notice at first. I live south of Buffalo, NY - you have to pick them up or MEET ME at the Audi Watkins Glen HPDE Tuesday, Sept. 22 - I'll have them there. Cash only (sorry).
