VEHICLE HANDLING STUDY: AN ASSESSMENT OF TIRE CONDITIONS

Seven hundred sixty randomly selected accidents occurring in Washtenaw and part of Oakland Counties, Michigan were investigated. Data relevant to determination of the potential role of vehicle handling in accident causation, principally tire data, were collected on 1044 vehicles in these accidents. Limited tire data were also obtained during random Michigan State Police checklane inspections in the summer of 1976. The checklane and accident samples were compared on tire pressure, tread depth, and carcass construction. Additional comparisons were made between subsets of the accident sample. The data reveal generally poor tire maintenance practices in both samples, with evidence that mixed carcass constructions and large inflation pressure imbalances are overrepresented in accidents, and low tread depth is overrepresented in accidents on wet or slippery roads. These conclusions are tentative because of the limited number of vehicles in the accident sample, and because the control group may not adequately represent the population which generated the accident sample. More definitive control-group data and development of a definition of vehicle-handling accidents are recommended.
