Overview

Objectives:

This study has measured road grip on wet, salted asphalt road at freezing temperatures for used and new winter tyres, with the purpose to investigate how the road grip for the three different types of winter tyres that exist in Sweden degrade by age and degree of wear. Also summer tyres were included in the study.

Methodology:

In total, 84 tyres have been tested, of which 31 were completely new while 53 were used. The tyres have been tested on smooth ice and packed snow.
