These tires use Tire Balls technology found on military grade applications. What is a TireBalls MCIS Inflated tire? An MCIS inflated tire is a conventional tire that is filled with cells designed to fill the cross-sectional space between the tire tread and rim, and sidewall to sidewall. Each cell is individual and independent of the others. Each cell is pressurized to an internal pressure nearly identical with typical tire inflation pressure for the tire and vehicle on which it is installed. The number of cells that fill a tire is a design parameter. For runflat applications more cells are typically used, thereby minimizing the effect of the loss of a single cell on the total tire performance. The cells do not fill 100% of the tire/rim void space, but typically 80-95%. There is a small amount of additional (interstitial) space between the tire/rim and the confined volume occupied by the MCIS cells. This interstitial space and inflation thereof is accessible through the traditional rim mounted inflation valve, and filled with air, up to standard operating pressure. The patented Tire Ball® Air Inflation System is comprised of multiple individually inflated, cells that fill the vast majority of the space within a tire. The Tire Ball® system is used in off road tires of ATVs, UTVs, light trucks, Dune Buggies, special purpose sedans, motorcycles and now HMMWV’s. The individual cells are made of a urethane material that is 10 times more puncture resistant than a typical heavy duty inner tube for motorcycles (up to 30x more in HMMWV cells). Each Tire Ball has a valve similar to a sports ball and is inflated with a standard needle. The system offers virtual flat proofing, along with improved “ride” qualities such as: enhanced suspension, greater traction, better cornering, and quicker braking. A puncture of a single Tire Ball® cell allows the rider to continue riding/driving on 90-95% of air volume originally present in the tire. This small amount (5-10%) of air loss is truly unnoticeable to the rider/driver. A major advantage for applications such as ATV/UTVs and Light Tactical Vehicles is you will eliminate rim to ground contact through the unique progressive increase in air pressure at the tire’s contact patch, enabled by the compartmentalization of air within the Tire Balls. These vehicles, which typically can run with lower tire pressures, can now possess great traction characteristics without the downside of bent rims and cut sidewalls which could flatten a tire.
