Buzzcut,, I always carried my chains with me in my 4x4 but never had to use them, Have always been waved thru chain restrictions because good tires and 4x4.
Last year going over the summit headed East I was waved thru during a nasty snow storm,, CHP told me I was the last one thru,They were shutting it down behind me.
Almost thru Truckee I had to pull over and chain the rears,, snow was building up so fast I was sliding with the crown of the road.
Sure was glad I had my chains,,,,,,,and that they FIT!!! Made it just beyond Boomtown before I took them off!!
Just this week I made sure they fit on the new truck,, My neighbor thought I was crazy putting chains on a new PU with 4 wheel drive!!! I just smiled and kept doing!!!
