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.
Rubber Run Flat Insert designed for military and special‑purpose vehicles:
· Compatible with 20‑inch, 21‑inch, 22.5‑inch and OEM‑specified sizes
· Provides bullet‑resistant and blast‑resistant support for emergency mobility
· Ensures a minimum run‑flat mileage of 100 km after tire failure
· High‑strength structure offering superior load capacity and impact resistance
· Maintains tire shape under extreme conditions to prevent excessive deformation or blowout risk
