Three VTI reports are presented. They document the results of tests on behalf of the National Road Administration and the Traffic Safety Office as part of the 1988 investigation on studded tyres. The investigation included a commission from the Government to the National Road Administration and the Traffic Safety Office in August 1988 to determine how road wear can be reduced through changes in the regulations on the use of studded tyres. The two authorities were also asked to study the consequences in terms of social economics of a prohibition on studded tyres and the possibility of applying economic constraints to limit their usage. The effects on traffic safety of various actions in this context were also to be studied. As a result of the Government commission, the National Road Administration and the Traffic Safety Office asked the VTI to carry out a series of studies on the road grip of winter tyres. The VTI has published the results in three reports: VTI report 354 "Road grip of winter tyres on ice'; VTI meddelande 605 'Study of the present status of studded tyres'; and VTI meddelande 606 'Field test of studded and non-studded winter tyres : subjective rating by taxi drivers'.
