what wheel size can i go down to for snow tires? I have a 2002 Audi 2.7T, and i have been looking for snow tires but dont know what will and wont fit on my car. If i could have some help that would be great. thanks

 

I'm old fashined, so I would say for best results (overall performance and responsiveness of the car) is recommended to go with the OE size: either 215/55-16, or 235/45-17, whichever your car came off the line with.
However, people who actually use winter tires on an yearly basis can help you better with your inquiry. Welcome to the forum
