Actually, you are only supposed to put 150-200ml or so per tire. The FAQ on the website says that it would then be under 5oz of added weight to each side, which would not require balancing if distributed evenly. That's assuming they were properly balanced to begin with.
Granted, that's all from the manufacturer's web site.
