The Effects of Studded Tires: A research summary report on the effects of studded tires

The 1969 Legislature of the State of Minnesota under Minnesota Statutes, Chapter 169.72, directed the Commissioner of Highways to conduct an in-depth study on the safety and pavement-wear effects of studded tires. This, the final report of that study, summarizes the research efforts and the results. The report is prepared for the specific use of the 1971 Legislature. The Commissioner of Highways is indebted to the many organizations that cooperated in providing information: The American Oil Company for conducting the pavement-wear tests; Kennametal Corporation for furnishing and installing studs in test tires; Cornell Aeronautical Laboratories for the accident study and analyses; the Minnesota Highway Patrol and other offices of the Department of Public Safety for accident reporting and survey coordination; and the many city police departments for supplementing accident reports with data required for the study. Participating cities were Brooklyn Center, Duluth, Edina, Grand Rapids, Mankato, Minneapolis, , Richfield, Rochester, Roseville, St. Cloud and St. Paul. Special thanks are due those states that contributed funds for defraying part of the project costs: Illinois, Iowa, Michigan, New York, North Dakota, Pennsylvania, Utah and Wisconsin. The content, findings, and conclusions expressed or implied in this report are those of the Minnesota Department of Highways. They do not necessarily represent the views of the organizations providing data for the report or the cooperating states.
