Floor pump use
Forgive me in advance, I'm new to all of this.
When picking up a new bike I was recommended a Lezyne floor pump, which I ended up buying. I didn't have a Schrader and the accessories were free, why not take the most expensive one they sell, right?
Anyways, I don't think I understand how to use it, which is odd because, well, it's a bloody pump.
Yes, remove the cap, open the valve, thread the tip onto the valve, pump. What happens on the gauge on my pump seems odd, though, it jumps up about 50psi per pump and decreases almost as fast as it increased. If I let it sit after giving it a few pumps it will return to 0, but the tire's far from deflated. In fact, I can't really feel the difference by squeezing the tire before and after inflating after a few days of riding. There's no obvious hiss or leak, so I don't quote understand what's happening.
Right now I just try to watch the peak of the needle with each pump and stop when that peak has reached about 110psi, seems odd though. It happens on both the front and rear tires.
I'm somewhat apprehensive about deflating a tire to see how well it pumps up just in case I can't re-inflate.
Any idea whether I'm just an idiot or what I should try? Thanks in advance!
