I know a guy who used fishing line or kevlar to wrap his tires (sort of radial tire effect) to keep them from ballooning. He used around 5-6 ties per tire and ca glue to hold the ties together.
He also balanced the tires and had a pretty intricate method of aligning the wheels for caster/camber/tow in/out.

I haven't noticed much balooning on the Proline 40 series velocity rims and bowtie tires.
