The Tire Ball® High Performance Inflation System Is composed of multiple cells that inflate the tire versus the inner tube or tube-less design tire which has one vulnerable single cell. A puncture of a single cell inner tube or tube-less tire results in a flat tire. The puncture of a Tire Ball® inflated tire results in a single flat cell out of many, not a flat tire, allowing many puncture situations to be ignored. Chances are, a rider will not even recognize the loss of air in a deflated Tire Ball®.
Tire Balls are the best choice for any rider who absolutely cannot have a flat tire during a race or on the trail. Developed by Wade Summers, father of multi-time GNCC Champion Scott Summers, Tire Balls offer a better alternative to Tech Tubes or Bib Mousse foam inserts.

Scott Summers says, "Tire Balls are like a smart system, the harder you hit something the higher the pressure goes."

The Tire Ball High Performance Inflation System consists of multiple individual inflation cells inside your tire - not just one tube. 21" front tires typically use 45 - 48 Tire Balls. 18" rear tires normally use 32 - 35 Tire Balls. Effective tire pressure can be varied for conditions by adding or removing Tire Balls or by adjusting the air pressure in the individual cells. Cell pressures can be adjusted from 8 - 9 lbs for woods riding to 12 - 13 for high-speed desert conditions.

Each individual Tire Ball cell is made from state of the art materials that are 10 times more puncture resistant than conventional heavy-duty neoprene tubes. Punctures are still possible, but very rare. Instead of losing all the air in your tire, only one cell goes flat, allowing you to finish the ride.

Novel idea, but I'll bet it makes pressure adjustments and installation a b*tch!

Isn't there another product like that, it is a solid rubber insert mad my Moose, Mousse or someone? There are issues with riding at certain speeds I think. http://www.procycle.us/main/mounting_that_mousse.htm

RE: Anyone hear of these?
 

You'll find these on "trials" bikes. Speed is deinatley an issue with the insert. But who rides a trials bike fast anyway. I only run 5 PSI in my TLR. If you pay attention to the trials guys, take a look at how much tire is in actuall contact.

Yea a kit for a 18" wheel is 200$

That is crazy expensive, but it would be some nice piece of mind if you were doing some serious remote riding to know that you wouldn't have a flat tire. I guess if you are going to do that kind of riding, though, you ought to be pretty good at trailside tire changing, huh. ..... Nevermind. :)
