I’ll second I’m not using a locker on pavement in snow unless I’m in deep running slow or near stuck (assuming selectable). For paved roads and snow nothing beats true snow tires, not 4 season but true snow tires. The difference is night and day. For intermittent use and super easy to put on AutoSocks are quite surprising as to how well they stick. I used AutoSocks last year instead of chains when chasing snow getting to and from the ski resorts. Still had the chains but never needed them with the socks. Off road, chains are tough to beat.
