Never drive in the winter in the mountains without chains, many times you may not need them but your really glad to have them when you get into the time you need them
I suggest bringing chains anytime during the winter season. Yes, the main roads get cleared quickly, but there will be dangerous ice on many residential streets leading to crashing into snowbanks or stranded unable to make it up or down the ice patches. Last weekend my street had 8 separate car crashes and that was with just 2" of snowfall. I even slide sometimes with 4wd. Have fun!
Check Calteans report. As of tonight you do not need it
