A road covered with ice is one of the most dangerous driving conditions and, in this case, tire plays an important role for traffic safety. The most of nowadays tires have good grip features on ice, but sometimes it’s not enough, especially when talking about the icy road condition. Many factors have significant influence on decrease of tire’s grip – one of them is temperature. The possibilities of using thermography in researches of tire and ice interaction were investigated in this paper. Measurements of tire and ice surfaces temperature were performed at Karlsruhe Institute of Technology with inner drum test bench using an infrared thermal camera. Longitudinal tire traction (braking and accelerating) were investigated and acting forces were measured too. Also optimal settings of thermal camera were determined and measurement results and discussion were presented.
