I am looking for some snow tires for my wife’s 2015 A3. I have found a set but the offset on the wheels is 20mm and opposed to the 46mm of the stock wheels. I am relatively new to the Audi family and want to know what to expect if I go with this set up. Most notably I see the difference will impact the scrub radius. Here is what I find when I enter the stock and after market info into wheel-size.com. Those with knowledge, input would be appreciated.
