pumping up tires with small power aircompressor

I have a small compressor, normally set at 110PSI. It has a small tank and very little volume.

Is it safe top off my tires with this compressor?

If the 110 is accurate and it doesn't fill past that and you are using 23mm tires it makes some sense. Whether you NEED that much pressure depends on your weight and the tire diameter but the common 23 and 25mm tires will both typically take that pressure with no problem.

You can if you have the correct valve on the tube or an adapter however for $50.00 you can get a bike pump that will fill both types and do it faster, quieter, and easier.

If the pressure gauge is accurate and the hose fitting fits your valve type, the size and capacity of the compressor doesn't matter.

It should work fine as stated, but I prefer a hand powered .

I use my compressor to fill tires all the time.

Me too! My compressor's output is set at 100 PSI so when my tire gets to 100 PSI and I can tell no more air is going in, I am done filling!

A pump is a pump, manual or powered. Oh, they are both powered just with different sources of energy! It comes down to pressure, how you measure it and if it is accurate. I would not count on the gauge on the compressor. Often I see 5 PSI differences between pressure gauges too!

One thing to remember tho is the fact that power air compressors quite often are fouled up by water that can get into your tubes. I go along with having a regular hand pump. Even at that my pump has a water bleed screw at the bottom.

Just make sure your tire bead is seated in the rim before you go to full pressure.
Or else!

+1 to don't trust the gauge

i use my compressor but I'm extra careful and never just assume the gauge on the compressor is spot on. I'll fill 90% and then use a real gauge to fine tune at the end.

And how do you know your "real gauge" is any better?

Hmmm,It's consistently accurate checked against a digital gauge, it's a quality tool designed to do one thing and that's the one thing I'm using it for. For starters. How do you know your ruler is really 12 inches? How do you trust your hammer to pound nails? The gauge on a compressor is there to give you a ballpark range for the proper operation of the compressor and component tools, and certainly is not designed for measuring bike tires psi. Notice I used the word tool several times. If only they made a reliable gauge for poor inter-personal skills and random uninformed negativity...now that would be something.

Common sense. How refreshing!
