Our tire fill product replaces all of the air in any pneumatic tire with a highly engineered polyurethane resin blend. In as little as 24 hours the mixture cures to a soft resilient polyurethane elastomer. Instead of riding on air, you ride on a soft cushion of polyurethane tire fill.
TyrFil is formulated to duplicate the riding characteristics of air. It is tough enough to be used in the tires of the heaviest industrial equipment and in the harshest environments.
