this post is mainly for curiousitys sake. when i got my used procomps, they had a bunch of white granular stuff inside. i'm guessing that this is what guys refer to as "equal". when i had my tires balanced and mounted, the shop just used regular weights and the tires seem like they are still a bit bouncy or out of balance. will adding equal to them help stabilize them and should i lose the weights? what are the benefits?
