One never knows if they are running the right air pressure because tire pressure gauges, even good ones, cant be guaranteed accurate. I have probably 5 different gauges, 2 of them " guaranteed to be accurate within 1/4 pound" and even they dont read the same. If the bike feels good when riding it, just use the same gauge on it everytime to fill it to the pressures that felt good.
They say you can go to a tire shop and they "may" have a master gauge that will check yours, but then again they may not. When I checked at my local multi store tire dealer, they did not, and they often use pencil gauges to check tire pressures, because it fits in the tire techs shirt pocket and they always have them with them. If you do find one to check yours, it needs to be checked periodically.
Tire pressures are not absolute critical, and can be run at various pressures. I've heard the tires need to be checked cold, at 68 degrees Fahrenheit for accuracy, and that pressure will be different every few degrees of ambient temp.
See on chart below set your tire at 40 psi at 68 degrees
at 50 degrees it will only be 38 psi

Same goes for torque wrenches.
