Hey, I have a quick question about tire chains, on hwy 120 I realize the roads are currently R-2.. what I'm wondering is how long the chain control usually lasts. If its just a few miles I'll just take 120 but if I'll need the chains on for 20miles or so it might make more sense to take 140. I realize conditions are always changing and chain control levels are as well, but since driving with chains requires a much lower speed if chains are required from say crane flat to the valley I would most likely take 140 ..
Thanks!
