Balance ET streets?

i was running tubes in my et streets. thats why at first i didn't think i would need them. they still needed to be balance with the tubes. make sure when they do balance them they use the weights that stick on the inside of the rims, and put some duct tape over them just to be safe.
 
Your not supposed to balance slick on a tires rotating balacner. Your supposed to use a bubble balacner. This is what it looks like.

Bubble balancers would be even less accurate than if you used a spin balancer. A bubble balancer will only get a rough estimate of a static balance. If you use a spin balancer you can get a dynamic balance...but with bias plies you'll never get it perfect either way.
