I have 3 original (factory OEM) 17" alloy wheels/rims and tires off a 2006 Audi A3 in fairly good condition. They have been used for about 10K miles. I lost one to a pothole incident less than a year after buying the car and ended up replacing all 4 with a new set. These 3 have been sitting in storage since then.

Size and Design: 17 X 7.5, 8 V SPOKE

They are one of the very common designs so you may buy 1 and use it as a full size spare tire (since the A3 only comes with a donut otherwise) OR buy 2 and create a set of winter tires. They will also fit the Audi A4 as well as VW Passat.
