I've been running RS4 8,5Jx18H2 ET20 with 255x35x18 tyres on my A6 1.8T Sport but they are too big for my car. They originally came off an RS4 or Allroad - according to Audi. I want to change the wheels a to a narrower wheel so they're up for sale. I'll put pics up in the classifieds soon. I'm also selling replica RS4 refurbed 7,5x17's with tyres (205x45x17) that I was going to put on my A6 but I want to keep to an 18. PM me if you're interested. I do have these advertised elsewhere and soon on ebay. Cheers.
