Yeah, you'd be pumping a loooong time on your car tires.
Allow me to plug Blackburn. Not that they make a significantly better pump than anyone else, but the service policy is top-rate. Years ago, I bought a blackburn floor pump from Nashbar. After about 4 years service, the gauge failed. I e-mailed Blackburn and they said "sorry, we no longer make that model. Send us the pump to check out, and we'll send you an new one."
So, I did, and they did. A nice TP-3 "trackpump". I used that for almost 10 years... Finally, the second set of pump-head rubber gaskets started to go. I e-mailed again, and again it was..."We no longer make that model. However, we will send you a new pump."
And again, they did. A shiny new Air Tower 3 with the clever head that handles all valves.
At this rate, I may never have to pay for a pump again...
