    Automatic tire chains

    Has anyone made or know of someone who made, their own automatic tire chains, like the on-spot or insta-chain or roto-grip systems?

    These systems are quite pricey and look deceptively simple.

    I would think it would take a lot of trial and error to make it fit and work right.
    Would be nice to be able to copy a successful unit.

    TIA

    But it seems that it needs a certain speed to start working, Starting uphill on a slippery road still won work. So nice idea but needs a lot of improvement before I'll buy it.

    I have never seen them in action, but I see them hanging under most of the fire trucks around this area. Not sure which brand. Some school buses have them also.
