I haven't used tire chains in50 years - since a couple years after I started to drive; although I will admit, there are times when they are necessary, like climbing a 1:3 slope after a thaw in a Model "A" Ford with Dad driving and me standing on the "bumperettes" (split rear bumper) hanging onto a rope through the back windows in order to put a bit more weight on the back wheels.
