Chains dragging under trucks ??
I was driving to work early this morning, it was still dark, and I noticed an ambulance in front of me had chains dragging on the ground from under the truck. They were just barely touching the ground but would send sparks flying every now and then. I asked my buddy what they were for but he didn't know either, but He said he has seen them on fire engines and other big trucks.
What are they for ??? Anybody know ??

I think he (itisedt) is talking about chains near the center underside of the ambulance. I have often wondered about it as well.....thanks for the explanation.

If they are between the rear tires and differential, they are automatic tire chains for icy, snowy roads. Most I have seen are air operated, They spin when activated, putting them under the tires. They really do help, so I have been told. If you get a chance look under a truck an you'll have abetter understanding of the system.
insta-chain on the web will show you what and how this works.

yup, tire chains. flip the switch, and they fold down and rub on the sidewall of the tire, flinging the chain under the tire for traction in icy/snowy conditions. they work great to.

I don't think hes talking about the snow chains.... I seen a few of the fire trucks, ambulance and some limos with a pair of chain on each near the center of the vehicle. I used to thought that if they dragged, it mean the vehicle is too low. But I also heard their for static also.
