[Christ]

I usually mount my own tires, then I take them to wally world to get them balanced... it's only $5 each... I NEVER stick anything inside the tire to balance it... having something bouncing around inside my tire kinda gives me a weird feeling inside..

I don't that there is any reason not to put stuff in your tires, but I prefer stationary weight... I never allow weights on the outside lip of my rims either. (They look like crap.)
