Accella Tire Fill Systems manufactures the only shock absorbing, flatproofing solution - TyrFil. TyrFil is a polyurethane liquid that is pumped into pneumatic tires to replace air with a resilient, synthetic elastomer core. This eliminates dangerous & costly flat tires on OTR equipment. Recent testing confirmed that TyrFil transfers significantly less g-force than solid tires. The harsh impact of g-force vibration transmission to heavy industrial vehicle operators and their equipment from solid aperture tires is known in the industry as Solid Shock. Not only is Solid Shock a major source of wear and tear on machines, but it's also a leading cause of operator injury. TyrFil offers a smoother, safer flatproofed ride. We Keep the World Rolling
