I'm a cover driver, so on a snowy day i always make sure to have a set of quick chains in the truck in case i get in a jam. Had to use them once so far and they helped. Sometimes i actually wouldn't mind a full set, then you can just deliver everything like normal and avoid the blown out disaster the next day from ec'ing everything. Maybe when i have my own route. No idea if we even have full chains for package cars here in NY
