A-Bodies in the snow?

My '66 Dart 270 made approximately 40 trips up to the White Pass ski resort on U.S. Highway 12 in the southern Cascade Mountains of Washington State back in my younger days (100 miles round trip on a twisting, snowy mountain pass). Ski racks attached to the gutters and the vehicle loaded with five growing teenagers. Never had any problems and there were likely a few reasons:

When I bought the car from the proverbial "little old lady" found an unused set of four "walnut" snow tires in the trunk. Don't think they make them anymore. They had tiny pieces of crushed walnut shells in the rubber resin for added grip. Didn't hurt that the holes were there in the tires to have the shop insert studs. Have seen a few guys mention studded tires in earlier replies, but I know they are not widely used in some areas of the country. The other key for the stock Dart was that the tires were really narrow on the little 13-inch wheels which seemed to result in less slippage. Some might not know, but here in Washington the DOT does not use salt, which likely leads to the fact that there are a bunch of non-rusted out older rigs in our part of the country. No salt=good for classic cars, but also good for tow truck companies dragging guys out of the ditch.
