Automatic chains for snow

They work great. That's why busses and fire trucks, ems have them. There like 3 grand installed. I'm getting mine early August


Be Safe Out There

I know there's a few fleets in Colorado that run them, and yes, they qualify as traction devices.

 

Lots of fleets in Colorado run them, they qualify as a traction device, BUT, it is still advisable to carry at least one set of chains. BTW, they add about 500 lbs of weight to your truck, make sure you factor that in when loading

 

When they first came out they were intended for use on any commercial vehicle.
Semi trucks were a little slower catching on than the Fire and Safety departments.
Not sure what they cost now, but to have a full set of auto chains installed on the truck was about 3 grand.
They are DOT approved or were a couple years ago, for semi.
When they were tested, they were just as good, but the operating speed was slower than with a properly installed set of chains.
You also had a bit more maintenance with them, because you had to make sure to clean them often to keep the motors from gumming up.
Bottom line, they were designed for those drivers that were to fat or lazy to get out and throw some iron.

 

Ones I'd like to get doesn't have motors. There's a disc that swings outward, contacts the tire and spins according to tire motion.
The disk is on a bearing to rotate freely and along the edge are chains attached that get slung under the tire.

 

School buses in Montana have that setup.
