The RTM friction tester can evaluate the friction performance of tires by material testing, and can reproduce a ring-shaped road surface surface in dry, wet, and ice conditions as a simulated road surface. A constant load is applied to a tire-shaped rubber material test specimen, and the frictional force is measured when the free rolling state or when the slip rate changes in the range of 0 to ± 95%.
