Extremely stupid question, I am embarrassed to post it, but I can't seem to pump air into my tires.
No matter what I try with my pump, nothing seems to happen. Is the pump head not sealing on the valve (Schrader)?
I've tried just having it over the valve and I can hear noise, I can push it further in and then there is no noise when I pump (and I can feel some resistance in the pump) but nothing happens. Kind of lost as what the problem seems to be.
pic related it's this type of pump
