Bicycle Repair & Ownership - How to inflate a bike tire

Inflating a bike tire requires an air pump and knowing the maximum pounds per square inch, or PSI, the tire handles. Keep bicycle tires at the right pressure...

Hi. I'm Travis from Mad Dog Cycles here in Provo, Utah and we're talking about how to inflate a tire. There's several or two different types of valve stems. This one for instance is a press a valve. The other one is a Schrader valve like the American ones that you see on cars. What you want to do on a press is unscrew this a little bit and maybe blast that open a little bit. Put the pump head on. Pull up on the thumb lock right there and go ahead and just pump away. Okay. Make sure and you check and see what the recommended pressure is for this tire like for instance this is about 80psi. So you want to top it off to about 80 if that's what you feel like you need in there. Go ahead and remove, pull out, screw that cap or screw that press the *** back down okay. Screw the cap back on. and that's it.
