Nine percent of vehicles had at least one tire that was bald, with a measured tread depth of 2/32nds of an inch or less. Along with other findings, this is presented in “Tire Pressure Special Study: Tread Depth Analysis”, the fourth in a series of research notes containing results from the Tire Pressure Special Study (TPSS) conducted in 2001 by the National Center for Statistics and Analysis of the National Highway Traffic Safety Administration (NHTSA). The focus of this research note is on results from the tire measurements. Previous topics of TPSS research notes included the study methodology, the results from the driver interviews, and the vehicle observation data.
