Foam Filled Flatproof Tires for Construction Equipment of all sizes. We offer traditional TyrFil and Superlite Safety Foam Tyrfil. The foam is pumped directly into the tire, replacing all the air inside the casing. Once cured for 24 hours, the tire has a resilient foam core that will not go flat, even after being cut, punctured or scraped. The result is a tire that provides a smooth, safe ride without loss of productivity. We also offer a full line of construction ties and steel & rubber tracks.
