Reduce rollover risk.

IS THE CARGO IN YOUR M1114, M1151A1, M1152A1, M1165A1, OR M1167 UP-ARMORED HMMWV WITH FRAG KITS (FKS) 5, 6, AND 7 PILED TOO HIGH!

IS YOUR TRUCK OVER-LOADED?

WILL YOU BE DRIVING YOUR HMMWV ON DEGRADED ROADS?

DOES YOUR HMMWV'S DRIVER LACK TRAINING OR EXPERIENCE?

IF YOU ANSWERED YES TO ANY OF THESE QUESTIONS ...

... YOUR ROLLOVER RISK RISES.

Reducing Risk

* Place and secure cargo as low as possible in the vehicle.

* Conduct driver's training.

* Stay within recommended payloads.

* Reduce speed before sharp turns or when road conditions are poor.

* Increase stopping distances when necessary, especially driving through sand, debris, gravel or rain.

* Check tire pressures when your HMMWV hasn't been driven for at least three hours.

Heavy Could Be Hazardous

AT THE BASIC GROSS VEHICLE WEIGHT (GVW)--12,100 POUNDS--RAPID STEERING INCREASES THE LIKELIHOOD OF A ROLLOVER AT SPEEDS AS LOW AS 35 MPH IN YOUR M1114, M1151A1, M1152A1, M1165A1, AND M1167.

GVW IS BASED ON AN UNLOADED VEHICLE WITH A PAYLOAD OF FOUR CREW MEMBERS WITH BASIC GEAR.

FK 5 ADDS 3,000 POUNDS TO THE GVW; FKS 5 AND 7 ADD 4,000 POUNDS; AND FKS 5 AND 6 ADD 5,000 POUNDS.

THE PRESENCE OF SAND, DEBRIS, GRAVEL AND RAIN REDUCE THE STABILITY OF HEAVIER HMMWVS EVEN MORE.

NO RAPIDS

Tire Pressure Formulas for Reduced Rollovers!

HMMWVS WITH FK 5 PLUS LOAD RANGE D TIRES/WHEELS EQUALS 50 PSI FRONT/50 PSI REAR TIRE PRESSURES

HMMWVS WITH FK 6 OR 7 PLUS LOAD RANGE D TIRES/WHEELS EQUALS NO SO! (THIS IS NEVER ALLOWED.)

HMMWVS WITHOUT FKS PLUS LOAD RANGE D OR LOAD RANGE E EQUALS 40 PSI FRONT/50 PSI REAR TIRE PRESSURES

HMMWVS WITH FKS 5, 6, OR 7 PLUS LOAD RANGE E WHEELS EOUALS 50 PSI FRONT/65 PSI REAR TIRE PRESSURES

Increase Braking Distance

At 50 mph on smooth, dry pavement, an M1114, M1151A1, M1152A1, M1165A1, or M1167 HMMWV with FKs 5, 6, or 7 has a braking distance up to 14 vehicle lengths. At GVW, the braking distance is ten vehicle lengths. Of course, increased loads and potentially hazardous road conditions further increase stopping distances.
