Hello Audi Folks! My 2007 Q7 currently is running with small 18 inch wheels and tires. I'm considering getting a set of 21" or 22" Peelers with Pirelli tires sized at 285/35/22....or maybe 285/45/22. The larger tires have about a 7% increase in rolling distance per revolution. I have a Vag-Com and read that it may be possible to adjust Speedo accordingly. I'm looking at replica wheels from an ebay vendor with a good history, they have wheel & tire packages the look attractive. But as I did the math I found that the overall package price was more than if I just bought the wheels and tires separately and had them mounted and balanced locally...by about $150 - $200. I'm probably splitting hairs here but I would like to hear your opinions. Should I go with the least hassle and by the package? Or just do it myself? Thank You.
