Long-Term Tire Storage – Phase V

NCMS Project #: 142088

Problem: As vehicles tire and rim sets are stored for long periods, the components of the system degrade.  At times, these tire and rim sets are unusable when they are taken out of storage.  Tactical wheeled vehicles use tires that are similar in composition to commercial truck and bus tires, so they face similar degradation challenges over the life of the tire.  Tire failure after long-term storage is a significant cost driver for both the commercial and military market.

Benefit: If the reliability of tires can be increased by reducing rotting and decomposition, it will drastically lower the number of injuries and deaths due to accidents.  All inventoried components containing rubber such as: track pads, seals, gaskets, shock absorbers, and protective sleeves can benefit from this technology which is developed to increase service life and reduce maintenance costs.

Solution/Approach: In Phase V, the tires coated with the redeveloped coatings from Phase IV will be evaluated on vehicles in extreme hot and cold temperatures at Yuma, AZ and Ft. Greely, Alaska, respectively.  Environmental testing of the coating formulations will prove out their resistance.  If the tire coatings can withstand these harsh conditions, they are expected to be able to withstand any climate
