Your tanks are grounded somewhat by your framework. It's got a few points of contact with the tanks in a tight fitting frame. That gives some continuity to ground if the metal is fairly clean.
Doing as you suggest removes any doubt about a ground on the chassis/frame. That is a good thing especially around propane where a stray spark or some static charge might choose to dissipate as you refuel.
You might also drag a small piece of chain to take all stray current to the earth, tires don't do that. Well, maybe airliner tires do etc but not vehicles that I know of. I could see those tires on a fuel transport that delivers to gas stations etc. They are a bomb ready to go off just as our buses can be
if certain procedures aren't followed.
