I need to buy tire chains before winter. I have been reading the laws and now I am REALLY confused. Am I right that in Colorado that all wheels on a single drive axle truck. Cables are not allowed and the only legal alternatives are automatic chains and wheel sanders. What does everyone carry? I know that I am not likely to use them, I doubt that I will ever chain up to drive into a problem area. I might have to use them to get out of trouble. I look forward to reading your inputs.
