Tire flaps are critical safety components when running tube-type tires on multi-piece wheels. They create a protective barrier between the tube and rim, preventing punctures from rim edges, spoke heads, or the lock ring. This flap is essential for maintaining proper tire pressure and preventing premature tube failure on large commercial trucks, agricultural equipment, and heavy machinery.
