My wheels are electrocuting me!
I have just discovered that I have a current/voltage running through one of my wheels (maybe all four - I was scared to touch the others). What could be causing this and how do you fix it? The only thing I can think of is that one of the brake wires has an exposed wire that is somehow touching the wheel.

Hmmm....full moon tonght?
I have trouble understanding what you mean by "electrocuting you" and having current/voltage in the wheel itself. If you mean you get a shock everytime you grab the wheel, I'd say your vehicle is parked under and touching an unshielded 120 VAC household wire somehow, but I'd guess you would'a figgered that out by now. The 12 VDC supplied by your battery isn't gonna have sufficient voltage to cause a shock to you when you're grounded.
If you mean you can get a voltage reading on your multimeter by grounding your wheel to a ground sink of some type, then I have no suggestions, since your tires should insulate the vehicle from grounding.
If there are any electrical engineers in the forum, maybe they could comment on the possibility of getting phantom voltage readings from the TPS systems that use RF to send a signal to the vehicle computer.
O-o-o-r-r-r, here's a stretching hypothesis: maybe if the ground is damp, and if your engine is running, and if there is a plug wire with faulty/cracked insulation, and if it's jumping to the frame, and if you touch the wheel or lean against the truck while standing in a puddle, then maybe you could get a shock--your ignition is putting 50,000 volts or more and could 'bite ya' if all the conditions were just right.
Or maybe it's just a full moon....and an empty jug of 'shine.

Oh, BTW, your brakes are ...
... hydraulically operated, and they don't require voltage or current to operate. The only electric system that is hooked to the brakes/wheels is the wiring that carries the signal from the mag sensor in the hub to the vehicle ABS system.

Yes sir, have seen this before. This is what you have to do, its a little confusing but if you use jumper cables, gauge doesn't matter, touch one cable to your tongue and the other to your private part. Trust me, nothing will happen. Go enlist help from a Chevy forum.

I'm going with static electricity.
I sometimes get a pretty sharp snap just after getting out of my truck and touching the door to close it. Did it on my old F150 and my 09' as well. Mostly only ever happens to me in the winter months when the ambient humidity is very low.
