Pump design has a lot to do with how easy it is to inflate your tires at higher pressures. I need to throw my weight into my floor pump to get much above 100psi--- and for something like my Crank Bros mini, I doubt I can get above 80--- ever.

I already blew out a tube a few months ago when I tried to go beyond that point so I haven't even tried again. The tires always feel solid but not rock hard (lol). I can just barely push the tread a few mm in with my thumb which I think (?) is just about right (someone correct me on this). Maybe the gauge is indeed inaccurate and it's reading 80 psi while the pressure is actually higher. It's my roommate's pump and i'm not sure how long he's had it. Doesn't look too old and I'm not even sure that age can affect its accuracy... Or can it?
I'm still probably going to get a new one in the near future.
Thanks for the info.
