Any one got a audi 100 90 > , Passat or an A6 that has a 5 stud space saver wheel??

If you have could you possibly tell me the tyre size and also measure the diameter of the wheel including the tyre and the total width of wheel and tyre.

And if anyone has one for sale that would be great, it won't fit on my S3 but should make a good spare for my vw camper if its much smaller than a stock wheel.

many thanks
