Eventually you just have to give up and say "close enough". If Mrs. spiz enjoys ride ride, it is just right.

 

I use the EZ tire gage .
It reads the same as my shock pump, it is very easy to use. only $12.69 .
i bought some other stuff so i got free shipping '
it was so good i bought three more for christmas gifts.

The Harley NON-digital is really good has a nice extender for reaching tough to reach valve stems (like the rear tire on an FLHRC, buried between 2 spokes) and also has a tread depth gauge. (My parts guy steered me away from the digital.)

 

I use the Cruz Tools Tire Pro Dial gauge:

It is accurate, good quality, holds the reading and has a nice hose to access the valve stem. It's about $20. They also have a digital model.
You buy their stuff through Amazon or J&S Cycle.

 

Like everything else in life, you get what you pay for
Just depends on how much you want to spend and what your needs are

Not to blow your theory, but pressure is pressure is pressure! Period! Regardless of whether a pump/gauge is high volume or low volume, made for a motorcycle, a bicycle, a car or an airplane, all pressure gauges would read exactly the same (within their stated accuracy) if they were all accurate. If you have multiple gauges that give varying results, then the only thing you can be certain of is that at least one of them is not accurate.

 

several people have mentioned this gauge and i have been looking at it..

so the shock pump/gauge is the accurate one of my gauges apparently...

that is good to know til i order one...had some wear issues on last tire due to tire pressure i think... i want to make sure this tire is at right PSI...so i know if that was case or another issue at work wearing my tires odd(cupping on outer third of tire)

 

I went through this sometime back. Had several gauges and none of them were the same when checking pressure. I went with one of these. Easy to get in between the spokes and is accurate.

 

is amazon only place do get these gauges everyone telling about? few people have told me about this one and the E Z TIRE gauge......both seem very good from reviews i have read....also the harley non digital gauge

 

Whatever gauge you decide on, select a gauge with a range appropriate for it's intended use.

For example, many manufacturers offer the same or similar gauge(s) with different ranges, i.e., 0-60 psi, 0-100-psi, 0-150 psi, etc. Your tire pressure is in the 30 to 40 psi range so a 0-60 psi gauge will give a more accurate reading than a 0-100 psi or a 0-150 psi gauge will.

Some of the gauges that have a fill valve built-in will have the higher range gauge. This is because if they had the lower range gauge a high pressure air hose could damage the gauge. If you buy one of these you sacrifice accuracy for the convenience of the built-in fill valve.

I use a AccuGage 0-60 psi with a 90 degree fitting that is very similar in design to the Harley model. Got it online for twenty some bucks and I'm very happy with it.
