if you go tire chains onboard you should practice putting them on so you can get your own routine going for it. if you run in the 11 westerns, this time of year it is a requirement to have them onboard.
knowing how to use them is key to any battle. of course, if you dont have to use them then dont, watch the roads and reports to know requirements and plan accordingly.
with practice you can install a full set to california requirements (full chain law in effect) to 30 minutes.
i couldnt find a video or walk through on an install for a big truck, but here is one for a regular pickup, will give you an idea, its all relatively the same, just truck chains (iron) is bigger and heavier. and alot wetter. so have a rain jacket and a towel.
it uses something new it says than chains. but its an idea
