New Snow Tires for 2011 Hyndai Sonata

I understand there is some sort of
sensor with traction associated
with my car/tires. I want to
purchase 4 new snow tires for my
2011 Hyndai Sonata (which has
good tread on the "all weather
tires" currently on it now) I am a
native Colorado snow/ice driver.
This car is the worst in snow..I
have almost zero traction and it
seems like the car is too light so it
fish tails everywhere. I drive very
slow and cautious.
QUESTIONS
1. What type of snow tires do you
recommend? I have purchased
Michelin Artics in the past and
they were amazing (on my Celica)

2. Can Discount Tire mount my
snow tires knowing there is a
sensor system they must contend
with?

Thank you!
