Service station robbery - not an urban myth

I guess they could also be using the steel brading/bands inside the tyres. One thing I am certain of, is that the tread on my tyres are great insulators - at least at 1000volt and at whatever miniscule current it uses.

As you say great insulators at weak levels. Thats why the steel braids aren't used to the best of my knowledge, and needs the rubber as protection. Taking steel out to the rim or to the road ie away from the protection of the rubber would present a few probs. corrosion for eg.

I was thinking more along the lines of using the braid within the carcass and the conductive rubber strip (if fitted) to take it out to tread

I suppose that's possible, but practical I'm not sure. You then have to get from braid to rim 2 joints differing materials and steel is not always used. Don't ask me why I ever knew this this but Google US Patent 58980747A Granted to Goodyear 1999. How many tyre co's use the invention I don't know but I have seen anti static line on motorcycle tyres, which I presume is derived from this Patent. Read thru that and you'll probably be able to win a pub quiz!!
