I'm over here in the Western side of the state and drive mine over Vail, Red Mountain, Molas, Coalbank, Monarch and Douglas passes several times each winter.
1. Put studded tires on all 4 wheels. Do a bit of research and get tires with a lot of studs and siping. The number of studs per tire varies a lot between different tires and manufacturers. Don't let the shop sipe your studded tires with their machine. Get a set of tires that already has it from the manufacturer.
2. Keep the stock tune or the lowest, weeniest tune you can get in your vehicle during the winter. I run the Bamachips 91 race tune in the summer but I drop down to the 87 performance tune during the winter to remove as much torque as I can and make the auto
tranny shift as smooth as possible (without removing my CAI).
3. Put a gallon jug of kitty litter in your trunk in case you stop and can't get moving again. It works as good as sand and isn't near as messy to store.
4. Drive with a light foot. It's easy to break the tires loose and being a rear wheel drive car it's that much worse. If you break the rear end loose, your Mustang has a hard time knowing that the pointy end with the headlights is supposed to face front.
