Then Turning up on the valves, I noticed that the caps on the outside do not have longitudinal grooves and are very precisely, so that they can be very difficult to unscrew. So far I can therefore attach only 2 caps, but I am sure that the will can turn on two other even if I clean the valve threads previously correctly.
2 days ago when tire pressure check I had the problem that the caps are very stubborn and when turning. After initial resistance, they gave then however. Well, insgesam I have mixed feelings regarding the purchase and am excited to see how the situation develops during the winter.
If there is a trick to use, I am grateful for advice.
