%X A linear friction tester is used to test stud and rubber friction on ice. Studs are metallic objects inserted into tyre treads to improve winter tyre performance. Special small-scale rubber specimens, with and without studs, are used in this study. To begin, the device itself is presented and described. Testing methodologies and procedures were implemented and are presented in this paper. The influence of several operational conditions, including ambient temperature, stud geometry, number of studs, normal load and sliding velocity, are investigated and discussed. In addition, modern imaging tools are used in conjunction with the linear friction tester. A thermal camera shows frictional heating in the small-scale specimens. A high-speed camera is used to visualise and analyse the contact area during the sliding.
