The study is part of an investigation concerning the possibilities of reducing road wear caused by studded tires which the Swedish Road Administration and the Swedish Road Safety office were asked to carry out by the Swedish Government in autumn 1988. The study evaluates the differences in driving characteristics between winter tires with studs and non-studded winter tires of friction tire type. It was carried out in traffic in Stockholm by means of subjective rating by taxi drivers. The time period was from Nov 1 1988 to April 1 1989. As an objective reference, tire data concerning stud protrusion, static stud force and friction on ice were measured on some of the tires used in the study. The drivers were of the opinion that studded tires were needed on icy roads during 26% of their driving periods. For the rest of the time the friction tires were considered as equally good. It was noted that the friction tires were less noisy than the studded tires. The stud protrusion was about 1 mm at the start and between 0,5 and 0,7 mm at the end of the test period. During severe ice conditions the measured friction was about twice as high for the new studded tires as for the friction tires. Worn studded tires with about 0,6 mm stud protrusion had about the same friction as non-studded tires.
