The Tires-Flat Proofing (Wholesale) industry involves the distribution of tires that have been treated with a flat-proofing solution to prevent punctures and leaks. These tires are commonly used in heavy-duty vehicles such as construction equipment, military vehicles, and agricultural machinery. The flat-proofing solution is typically made of a polyurethane foam that is injected into the tire, filling the voids and creating a solid, puncture-resistant core. This process increases the lifespan of the tire and reduces the need for frequent replacements, saving time and money for the end user.
