Porsche!!! and awesome rims!

Hi, I urgently need your help. I bought cheap Porsche complete bikes with one year old winter tires (about 3-4 months, so almost new) without damage for 280 euros. What do you think at the price? Is ridiculous, right? Here are pictures from an auction at Ebay, where someone auctions, but without tires: http://cgi.ebay.de/ws/eBayISAPI.dll?… Now my real question: How do I get them registered on my Golf 3 Vr6 without having to make a headstand. Please help me if you have experience with rims of this type or size. Here are the dimensions and a description of the rims: Complete winter wheels on aluminium rims “Only 1 season driven / 911 Porsche” 2 x front DUNLOP Winter Sport M2 Tyre size: 205/50 R17 89 V Profile depth: 8 mm 2 x rear DUNLOP Winter Sport M2 Tyre size: 225/45 R17 91 V Profile depth: 8 mm Complete wheels on 7.0 inch ET 55 (front) Complete wheels on 8.5 Inch ET 50 (back) PLEASE HELP ME AND GET ME HELP FREE TIPS!!!!!!!!! Merci. Greetings Michel
