Airsoft BBs in tires for balance

Has anyone done it? I was looking online researching balancing beads and they work well from what i took away. But, actual balancing beads are fairly expensive for what they are and i asked chatgpt if i was able to substitute rice instead, and it told me why that was a bad idea. Instead it offered 6mm BBs, 500 per tire, you can buy a can of 5000 for $15 vs balancing beads at $40 and they hold the same properties of being water resistant and what not.

Anyways, i do my own mount and dismount of tires at home and the issue i been having was they are always out of balance afterwards. Even when i try to balance them with the sticky pad weights using a cheap harbor freight balancer, its never on point. I think ill be switching to beads on all my tires from now on. Just wondering what the driving experience is with them if anyone has them right now before i attempt this.
