Long-Term Tire Storage – Phase IV

NCMS Project #: 142053

Problem: 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.  There is no repair process, so tire failure requires replacement, thus increasing the maintenance, logistical, and life cycle costs for commercial and military vehicle service centers.

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: The Phase IV effort will focus on refining the solution that was developed during the initial phases by addressing the shortcomings and then testing and validating the extent of the protection that the coatings provide over time to understand their limits.  It is a logical final step in the technology to demonstrate the effectiveness of the coatings developed to protect the inside and outside of a tire from oxidation, UV degradation, ozone, and biodegradation.
