is the gauge on the harley shock pressure pump the most accurate ?

because if i check my tire pressure with my tire gauge(2 dif ones)
tire gauge reads 40 PSI...put shock pressure gauge on and reads 37 PSI?

i assume the shock pump gauge should be most accurate

anyone know for sure

 

I would agree, but you'll need to use a third gauge one time to be sure.

 

what made me check...was i had rear tire replaced...he said check front PSI for me...said was at 37...where he runs his... i had just put mine front at 40PSI...according to my guages....

so i checked with shock pump....it read 37PSI..... si i check AND ADJUSTED 3 TIMES.... everytime came out 3 PSI different....both my tire guages read the same and shock pump guage was 3 PSI less everytime....

so i decided to try on forums for opinions LOL

 

If cost means anything, the shock pump had better be more accurate!

 

Cost is a big factor in accuracy in a tire gauge.
You didn't say how much you paid for your tire gauge, those pencil style gauges are know for being off

FYI.........The tire gauge I use for my slicks at the track, was $65.00

 

its is a pencil guage....i couldnt find much at my advance auto parts that had right angle for checking motorcycle tires when my old good guage broke

any ideas where to find good guage?

 

I use a digital one I bought at walmart... works pretty good lol

 

what kind you have

 

Get one of these. They're $29.95 at the H-D dealer. It has a right-angle end that makes getting at those valve stems easier.

 

I don't know if it matters, but, the shock pump is low volume, low pressure. Most auto pumps are high volume, low pressure. Most bicycle pumps are low volume, high pressure. So, that being said, the gauges may have different settings based on the various expectations.

Just a theory, but, I do notice my bicycle gauge reads differently than the gauge I use on the HD that also reads differently from the gauge on my tire inflator.
