Hmm, sounds a bit implausible that significant static can be built up
accross a thin layer of grease with moving metal parts on both sides, but
maybe.  However then you said:

Then why would new tires fix the problem if the static buildup is in the
bearing, not accross the tire insulating the chassis from the ground?
