This is a great find! When I have to replace my tires, I will try this if the tires need balancing- I would like to bring up something that you may already know. All tires,car,motorcycle,scooter have a yellow spot of paint on the side wall-this is the lightest part of the tire. This spot should be positioned at/inline with the tire valve stem- which is the heaviest (add valve stem). many times on smaller tires like scooter and some of the smaller motorcycle tires you may not need to do anything to balance it. Many tire shops don't even know this and will just mount the tire with the spot wherever, some times contributing to the out of balance of the tire. I keep about 4-6 oz. of slime in my dual-sport and dirtbike tires for obvious reasons (thorns) and this stuff works to also balance the tire,like the item you have found.Thanks for sharing the site on the ceramic balance beads-what an easy fix. Woud you mind sharing what the cost of this product is?.
