I have a Schwinn floor pump from Canadian Tire with a built in gauge.

I wanted to check/confirm it's pressure readings, so I pumped up the tire till it read 60 psi.

Then I checked it with 4 automotive gauges... 2 different brand dial types, 2 metal tube types...

NONE of them read the same thing. One of the dials read 50ish lbs, the other 45. One of the tube types read 35, the other 55 (rounding these off from memory)...

So out of 5 gauges, I really have no idea what pressure I'm actually getting to.

I need to find an accurate gauge. The pump itself on the other hand seems to work fine.

Cheers TRJB
