Bike Tire Pump Not Working

The volume measurement for balls will not register correctly as the guage is specific to bike tires.

Bike tire pump not working. I regularly pump my 700 x 42 tires up to 100 lbs 30 lbs. One going to the bike tire and one to the outside air. Bicycle pumps take a real beating. Over the recommended limit with an old zefal hand pump that s curved because a car ran over it when it fell off my bike one time.

This pulls in air from the outside but closes the valve to the bike tire. I doubt your pump is the problem unless the rubber of the fitting is torn or old and brittle or unless you re using the wrong pump head for the valve style. Knowing how to use your mini pump can take some of the worry out of going on a long bike trip. Most hand pumps used to inflate bike tires are reciprocating pumps.

In this video i show a way to bring a bicycle pump back to life by re greasing it. The two readings are psi or pounds per square inch and the second is the metric equivalent. On the other hand you need a schrader valve which has threading for a screw on cap and small metal pin inside. I also give information for fixing different issues at the end of the video.

They have a piston inside and two one way valves. You force them push on them knock them around and take them everywhere with you on your bike collecting all kinds of dirt and crud. The bicycle pump with presta valve would include a thin and threaded metal cylinder which will not work for your car tire. As you know the pump is intended for bike tires but can be used for balls too.

When you go to inflate the tire most air leaks out and one hears a hissing sound not coming from where the. It s a wonder they work at all. When the pump is pulled up the pressure inside decreases. Some bike pump with use will start to leak where the tire valve enters the pump head.
