I recently purchased a 1992 525it. I was wondering if I would be able to use my extra wheels with almost new snows from my 1994 audi 100csq. The wheels are both 15". The bmw tires are 225/60 R15 and the audi tires are 195/65 R15 91H. The wheels and tires are in great shape. I wish to avoid spending $500-$600 on a new set of snows. What are your thoughts?
