WebIn general, studies show that the maximum side friction factors developed between new tires and wet concrete pavements range from about 0.5 at 30 km/h to approximately 0.35 at 100 km/h. For normal wet concrete pavement and smooth tires the value is about 0.35 at 70 km/h. In all cases the studies show a decrease in friction values for an ... WebThat factor is called the coefficient of friction and is denoted by the Greek letter μ, pronounced “myew”. It varies with the pavement, the type of rubber, its temperature and age, road conditions such as the presence of water and sand and leaves, and whether the tire is sliding or rolling.
