Tire Pressure Special Study: Data Documentation.

摘要

In 2000, Congress passed the Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act. Section 12 of this act directed the Department of Transportation to complete a rulemaking requiring implementation of a warning system in new motor vehicles indicating under-inflated tires. In response to Section 12 of the TREAD Act, NHTSAs National Center for Statistics and Analysis (NCSA) conducted the Tire Pressure Special Study (TPSS). The TPSS was designed to assess to what extent passenger vehicle operators are aware of the recommended tire pressures for their vehicles, the frequency and the means they use to measure their tire pressure, and how significantly actual measured tire pressure differs from the manufacturers recommended tire pressure.
