The first friction clutch on Qashqai, before that I did not believe in this type of rubber. I skated the winter and, for me, even better than many of the spikes that were. Firstly, it’s quiet, and secondly, it almost didn’t lose its grip, and the friction clutch is much more comfortable when early spring begins and there are warm days. It behaves well in corners, it swallows small pits with a bang, there is even disk protection, which is also important for me, since my wife often drives a car.See full review
