I keep mine on spare rims. Doesn't wreck the roads, and doesn't wear out the studs when you need 'em. Semi trucks on chains will ruin the freeway in three days though. There were massive holes after 2008 in I5.
Drove over Willamette Pass last night, it was 45 and pouring rain. Made the drive easier without snow, but the rivers of water in the chain ruts was kinda sketchy when driving. Bly mountain was nice a few days ago though.
