I saw it on Mythbusters, but what is the physics behind it? I think it has something to do with pressure.Thanks, Ian
I don't think this is a drill.
I suggest that you buy a set of quick fit tire chains from a les scwab store and then watch the weather reports for the last week before heading over the pass, try to get to the top in the 2pm bracket between the storms. I leave the weather channel on all the time a week before I leave, and make a point to watch the big green radar maps of the storms as they go over the pass , and leave a day early or a day late (if possible ) to miss bad weather. Studded tires are way more expensive, less muss and less fuss than chains, but if thats the only time you need them thats a pile of money for no reason. A lot of people think you need chains in passenger vehicles, this is not true, some passes are 10,000 lb vehicles or above require chains. So your best choice for expense will be tire chains like the quick fit type, and if you do not use them by april of next year , you can return them for a full refund. Which is what I do. good luck drive safe. chains are for low speed only 20 miles an hour or less will make the chains last a lot longer.
I loved fire alarm drills in elementary school because we were allowed to leave government child prison for fifteen minutes and stand outdoors. I am not a dooms day lover but wanted to say that some of us just liked getting outside.
