Winter tire question
Some basic guidelines for snow tires:
- The cold temperature (sub 40F degrees) makes summer tires into hockey pucks.
- Snow and ice need Winter tire's bigger grooves and micro grooves to give traction, turning and braking power.
- All seasons are a compromise between summer and winter tires.
- The smaller the tire width, the better the grip and penetration into snow.
- The smaller the diameter of the wheel, the higher the sidewall for pothole protection. Nice for NYC or other war zone roads.
- Changing tires on nice alloy wheels every 6 months will cause them to be damaged or scratched by the garage.
So if one lived in Alaska or Buffalo where snow and cold are constant, then go with 17" or 18" winter spare wheels and hard core snow tires.
In Philly, I went with 19" winter wheels and medium aggressive winter tires like Blizzaks.
If you live in a warm winter state like Florida or city like LA, you can stay with your 20" wheels and risk getting them scratched but then why not just change to 20" All Season tires permanently and just sell your summer tires?
If you can afford to drive an A7, then you likely can afford a set of appropriate winter wheels and dedicated winter tires to protect your family and A7 from accidents. If the winter wheels look great, then that is a bonus and keeps the look new every 6 months.

I plan to have my A7 for a few years and want optimum performance and safety. Heck, I will get the Stasis chip to boost power to 390 HP and get 5 sec Zero-60 acceleration but that is my priority.
If the $2K is too much for you for extra wheels & tires, then go with the 19" all seasons for the N.NJ area. You will do well either way.
On second thought, I would even go with 18" wheels for the NYC potholes with a second set of winters from Thanksgiving to Easter. Friend of mine with 18" AS tires on an Acura TL blew out a tire on Long Island potholes every year and even bent a rim or two. Tough area to drive in winter!
