Permeation of truck tire innerliners at in service temperatures
In-service tire disablements are a significant factor contributing to crashes, injuries and loss of life globally. A study of 2016 data showed tire malfunction was a factor contributing to 733 traffic fatalities in the United States alone. NHTSA reports a similar number of fatalities from tire related crashes in 2017. Tread and/or belt detachments are one of the most serious issues, as they are often associated with a loss of vehicle control. In an effort to mitigate such events, it is important to have tools to investigate root causation. Permeability of oxygen from inflation gas into the carcass has been identified as a significant contributing factor. It is now well established that at least one major tire recall had its source in tire rubber
oxidation.
