how much air is 100 PSI in a bike?

Question

I have a pair of fat boy tires. The size is 26X1.25 and it says to put 100 PSI. How do I mesure the PSI?

Thanks for your help.

Answer 1

the pump at the gas station should have a built in pressure gauge to measure 100 pounds per square inch.
However, stop at 90.
The air will expand in hot weather and your tire will blow.
100 psi is the recommended max for your tires, not the mandatory level.

Answer 2

PSI, pounds per square inch, is a measurement of air pressure. You need a gauge to read. Some bike pumps have one attached. If not, you should be able to get one at a cycle shop. Or, you can even go to a gas station that has air for tires. Just fill your tires with some air, then stick on the gauge to measure if you need more or if you've gone too far.

Answer 3

That is the pressure, you need a tire pressure gage. 100 PSI means 100 pounds per square inch of air pressure.

Answer 4

PSI (pounds per square inch) is the English unit of measure of pressure. If using SI it would be Pa of kPa or even MPa (being Pascals, kilo-Pascals, and Mega-Pascals, respectively). To measure this parameter you will need a tire pressure gage which can be purchased at most automotive stores.

Answer 5

You should get a pressure Gauge for your bike. Don't rely on the one at the gas station. They are not accurate and could damage your rims due to the massive amount of air quickly delivered.

Answer 6

You need a tire pressure gauge. Available at any hardware store, car parts store, or supermarket. Most gas station air hoses have a gauge built in.

Answer 7

When you inflate the tires, a little gauge pops out. it will tell you the PSI, if not, go buy one.

Answer 8

You can buy a tyre pressure gauge or if you need to check when you are inflating the tyres, could find a compressor with a gauge on it.

Answer 9

with a tyre pressure indicator,
but ,do not trust the pressure gauges at a service station as they usually inaccurate.
