What are the best tires for winter driving in the Audi A7?

I live in a cold and snowy climate and want to make sure my Audi A7 is equipped with the best tires for winter driving. What brand and model do you recommend for optimal traction and safety?

I highly recommend the Michelin X-Ice Xi3 tires. They have excellent traction on snow and ice, and also provide a smooth and quiet ride on dry roads.

I've had great experience with Continental WinterContact SI tires on my Audi A7. They offer good grip on both wet and snowy roads.

I've found that Pirelli Sottozero 3 tires perform well on my Audi A7 in winter conditions. They have good traction on both snow and ice, and also provide decent handling on dry roads.
