I have a 700 x 38c tire with a Schrader valve I just did a puncture repair on. The recommended pressure for the tire is 75-100 psi (520-690 kPa). I would normally just inflate the tire until it felt about right, but since I had recently purchased a digital tire pressure gauge for my car I decided to use that.

I pumped it up to what I thought was about the correct pressure then checked it using the gauge and it was only at 25 psi (170 kPa). I continued inflating the tire with my hand pump until it became difficult to continue adding more air and it was still at only 37 psi (250 kPa).

I just don't see how it would be possible to inflate it to anywhere near the correct pressure.

According to the label, the gauge is also suitable for bicycles and has a range up to 100 psi (690 kPa).
