>>My question is: Do you put studded tires on a Quattro or is everyone driving with regular tires in the snow?<< Those are extremes. I avoid studded snows, but any car with wide, 50-series summer tires will be very unstable in the snow. For best winter performance either get narrower all-season (M&S rated) tires or narrower snow tires. Stud are often illegal, and ruin the ride/noise. Grant
