Automatic cycle machine suitable for inspecting both inside and outside of tyres for passenger and light commercial vehicles from 10” to 17,5”. The inspection can be performed under the best working conditions since the tyre rotation is carried out at even speed, without any vibration and with a strong lighting supplied by a lamp collocated in the middle of the tyre. Rotation is possible in both directions and can be stopped in any position. As soon as the 360° rotation is completed, the machine puts itself in rest position automatically. Optional: Central roller group.
