M-ATV run flat inserts. Built for the fleet that pairs MRAP armor with all-terrain mobility.
The MRAP All-Terrain Vehicle pairs MRAP-class armor with off-road mobility, and every corner of every M-ATV runs on a run flat insert. The Toota Group supplies segmented antiballistic polymer inserts built to NSN 2640-01-599-6284 as an alternate item — field-serviceable, quoted and built to order. CAGE 93ST9. We are not the approved source of supply; we are the alternate.
Armor where the terrain is worst — mobility has to survive it.
The M-ATV was bought for the mission profile where MRAP protection and mountain-road mobility had to coexist. Its wheels take rough-terrain damage and ballistic threats at once, so the run flat insert carries the vehicle through deflation events that would strand a lighter truck. Tread rides on the insert during run-flat operation — the insert is a wear item the fleet plans around.
- MRAP-class loads — heavy armor per corner, on- and off-road
- Terrain duty — rock strikes and rough trails drive deflation and wear
- Holds the bead — the deflated tire stays seated at speed and under maneuver
- Sustainment priority — inserts are consumed with tire replacement over fleet life
Total air loss, bead seated — and the M-ATV keeps climbing. The Toota Group insert under load.

Static RunFlat for multi-piece wheel assemblies.
Three pieces beat the solid ring.
Solid one-piece inserts need a hydraulic press to fit, degrade from heat during run-flat operation, and often end up single-use. Segmented polymer changes the math for a motor pool:
| Factor | Segmented Polymer (ours) | Solid One-Piece Insert |
|---|---|---|
| Weight per wheel | ✓ ~15% lighter — less unsprung mass | Heaviest option |
| After a deflation event | ✓ Inspect, swap damaged segments, re-use | Heat degradation — often replace whole insert |
| Deployment logistics | ✓ Segments stack flat, ship lighter | Bulk shipping, heavy handling |
The grease is part of the system.
During run-flat operation the tire tread rides directly on the insert, and heat is the enemy. Purpose-built run flat grease keeps friction and heat down through the mobility window — in the same NSN line the fleet already buys: tube NSN 2640-01-419-6200 (one per tire at installation) and 55-gallon drum NSN 2640-01-457-5552 for fleet-level maintenance programs.
What a Fleet Order Looks Like
- Insert kit: NSN 2640-01-599-6284 (1 per wheel)
- Lubricant — pick ONE: tub (52 oz), tube NSN 2640-01-419-6200, or 55-gal drum NSN 2640-01-457-5552
