Warfighters, you may have heard the Army is testing a new winter tire for HMMWVs: the KO2. KO2 winter tires have a three-peak mountain snowflake (3PMSF) rating, which means they’re considered severe snow service-rated.
For now, the KO2 tires aren’t authorized outside of the units that have been performing user testing.
Until KO2s are more widely available, units will continue to use tire chains to ensure cold-weather mobility.
Get a tire chain assembly kit with NSN 2540-58-001-1822.
