Air Gauge

I have had a Cycle Pump air gauge several for years. I just purchased another Cycle Pump air gauge. I notice the new one reads 4 more psi than the old one. For example, the old gauge reads tire pressure at 40 psi while the new gauge reads the same tire pressure at 44 psi. Is this typical? The gauge is pricey and I was hoping for good quality. While disappointing, I can live with it. I suppose I need to calibrate my gauges against a gauge I know is accurate. I am thinking about taking my bike to a shop and inflating it with their equipment and then checking my gauges, but that assumes the shop has accurate equipment and I suppose their stuff could be off too.

This reminds me of trying to set your watch to an accurate time source before modern technology made getting the correct time easy. Any suggestions?

I had mine checked with a m/c tire guys tire changer that had just been calibrated. Mine was off 1/2# at 42#'s on the rear tire from his tire machine. I considered that close enough. Best rest will make it right if it's off, but I have a hard time thinking they sent a unit out that far off.

I had Dave repair/recalibrate my gauge. Great customer service.

Thanks guys. I will do that.

Mine is 8 years old. Dave charged me $10 to recalibrate it. That is is essentially his cost to mail it back to me.

Never have 2 air gauges. Always 1 or 3.

Assuming that you're extending the analogy of having two wives, are you certain that 3 wives is better than 1? While it's likely that 2 of the 3 will always be teamed against the 3rd, on a rotating basis, does that make the team of 2 any more correct than the odd ball? And, if the oddball is wrong, your current friendly wife has just led you astray to the enjoyment of the opposing team. Just think, it might be a long time until those alliances reform around some other issue. Until then, you're the dimwit that listened to muffin brains.

No. I would say, just have one. It might not be correct, but you'll have peace of mind.
