I've been told to pump my tires to 100 psi. The trouble is that pumping to that high tends to cause air to leak out of the head. When I got to pull the head off of the valve, it's usually stuck and more air leaks as I'm pulling.

What is the proper way of doing this? Also, I think it's nearly impossible to use a mini-pump to inflate those tires considering the trouble I have with floor pumps!
