Rubber Run Flat Insert
Rubber Run Flat Insert
A rubber run‑flat insert is a reinforced support component made through rubber mixing and vulcanization. It offers high elasticity, strong load‑bearing capability, and excellent impact resistance. In the event of a tire blowout, the insert helps the tire maintain its shape and support, reducing vehicle instability caused by sudden air loss, minimizing braking shock, shortening braking distance, and improving overall driving safety.
