The laws of vacuum is that all air is sucked out and the space will be filled with what is available.

But surely foam tires are like sponges...if you soak a sponge and spin it thousands of revolutions, eventually all the liquid would come to the surface and off the sponge, no? I honestly don't see how tire additive would "stick" to the foam even if a vacuum is employed.

The rotary machines don't spin that fast. Vacuum isn't about the sauce "sticking" it's to get it soaked in further so it softens the foam down inside as well as on the surface.

He is refering when driving.

The sause needs to react with the rubber and has to dry up

alexlok

Yes, that's it.

Assuming the wheels are sauced using this vacuum technique, would one need to re-sauce the tires each time the wheels are used or is one saucing session sufficient?

Do you have to submerse the tires? Or applying the sauce to the tires and then vacuuming them work as well, unsubmerged?
