    Hofmann, Kaaren L. ;
    Hunt, Liz
    1995-07-01 | PDF
    Rutting caused by studded tire wear has become a major issue in Oregon because of the impact on the infrastructure and the increase in driving hazards. It is estimated that the cost to mitigate the damage from studded tire use in 1993 alone is $42 million statewide. The ruts caused by the studs lead to reduced pavement life which increases the life ...
