My family moved from Chicago to Green Bay when I was a kid, in 1975. At that time, studded snow tires were legal in Illinois, but not in Wisconsin. My father had bought a hardware store in Green Bay, and I remember him, and a mechanic who worked for us at the store, using pliers to pull the studs out of our car’s snow tires.
You do see something similar done when a natural disaster (like a hurricane or tornado outbreak) knocks down power lines in an area; I’ve seen convoys of utility trucks heading hundreds of miles to help in the emergency response.
But, in this sort of case, as thatguyjeff notes, it seems to be extremely rare. Let’s hypothesize that Wisconsin were to send a bunch of snow removal trucks down to Atlanta. It’s 800 miles or so from Milwaukee to Atlanta, which means a full day (or maybe more) of driving just for the plows and drivers to get there. Build in some time to do the actual snow removal, rest time for the drivers, and the trip back to Wisconsin, and the trucks could easily be gone for three to five days.
What happens if it snows back in Wisconsin in the meantime? Weather forecasts are pretty good, but by no means perfect, especially once you’re more than three to four days out. The highway departments back in a northern state aren’t going to want to leave themselves less then fully prepared to handle their own roads.
It’d be one thing if, say, Atlanta were buried under three feet of snow, and then it became a humanitarian effort (with lives truly on the line). But, a situation in which Atlanta residents would be stuck in their homes for a day or two, until a few inches of snow melted?
Well, the three days are up… and right about now all that snow/ice is melted. The Temps are probably up to 70+ and Blue Skies by Greg Allman are probably playing on the radio again.
Probably time for anyone in the region to bring their beer indoors before it skunks… and sulk about why your daughters cut offs are… so dam short.
Congrats, Atlanta! It’s Summer again…
That shows what you know, Count! We won’t hit 70 degrees until Friday. Long winter this year…
OTOH, Greg Allman plays ALL the time.
Oh, like you invite me down to the BBQs so I’d know… 
Hey, you skipped last summer’s Atlanta Dopefest, so kwitcherbitchin’…
" I’ve got a brand new set of studded tires, you’ve got a pair of pliers.
Told the Statie they were dual-ply, turns out I’m a liar ! "
