What Is a Runflat System for Military Vehicles?

Posted July 21, 2026

Definition

A runflat system allows a vehicle to continue driving after a tire puncture, typically for 30+ miles at reduced speed.

Types

Composite (Toota's specialty), foam-filled, beadlock, and internal support ring systems.

Military application

HMMWV, JLTV, FMTV, and MRAP vehicles all use runflat systems for battlefield survivability.

Composite advantage

Lighter than foam, no heat buildup, reusable after puncture, easier installation.

NSN reference

Toota Group supplies composite runflat systems under CAGE 93ST9 for DLA contracts.

Installation

Bolt-in design, no special tools required, fits standard military wheel assemblies.
