downsizing for winter tires
 

Hi

I recently purchased a 2014 Audi Q5 which is equipped with 20'' summer tires (255/45R20).

I need to purchase winter tires and rims and I understand that I can come down in wheel size and increase rubber depth to improve holding in snow etc.

Can someone advise as to what size tire I can come down to and still fit brakes etc.

thanks for your help

cheers
