Ice or snow? Ice, pretty much useless without making chains or putting bolt/screws through the inside of the tires. Snow, you just need large floaty soft compound tires and relatively soft shocks/springs for added grip.
I run HPI Savage GT (original savage) tires and losi aftershock tires for my winter running. Both have relatively tall side walls, so they flex more, which is more forgiving on landings and better for traction. They are also a softer rubber compound than many I've tried which doesn't get stiff when it's cold. The aftershock tires are softer/wider/taller than the HPI tires. I run those when the snow is fresh and fluffy. I run the savage tires after the snow has thawed/froze which the truck stays on top of more.
