Runflat vs Foam Fill vs Beadlock: Military Tire Comparison
Posted July 24, 2026
Runflat inserts
Lightest option, reusable, bolt-in installation, 30+ mile run capability.
Foam fill
No air pressure needed, heavy, permanent, heat buildup at high speed.
Beadlock wheels
Mechanical lock keeps tire on rim, requires special wheels, no run-flat capability alone.
Composite runflats (Toota)
Best balance of weight, cost, and performance for most military applications.
Cost comparison
Runflats are the most cost-effective over the vehicle lifecycle.
Recommendation
Composite runflats for general purpose, foam fill for extreme environments, beadlocks for off-road only.
