Good tire pressure gauge?

[Milestones]

I've been looking for a good gauge - a few (below) but am open to any recommendations. Wish list: accurate, well built/will last, has a bleeder valve and is easy to connect w/o weird angles etc...

The motion pro one looks solid and $$.

Thank you

This is the one I've been using for quite a few years now. Accurate (compared against 3 digital gauges and its right on), cheap, has a bleeder and you can fill it from there as well.

Best $20 I ever spent.

That is a nice find. I just ordered one. Thanks.

I did a lot of research before settling on this one.

They are locally made in USA and had some of the best reviews that I could find.

Pressure gauges have really one purpose right? They are designed to tell you, accurately what the pressure is in a volume/container.

The problem is, most gauges under $100 don't do that job. I have done extensive studying and testing of numerous gauges friends of mine had and I had, which had staggering results. Out of 10 gauges tested, the accuracy varied between 5 psi and 2 psi off. Thats right, the closest gauge was 2 psi off.

We then did a few other tests like heating them up, cooling them down and banging them on the ground to see if the result changed and in all 3 cases, the result changed. Not only were the gauges not accurate, but they were more or less accurate depending on the environmental conditions, which makes sense.

Due to the fact that 2 off wasn't good enough for me, I wound up doing research on what gauge to buy. The one I bought a

Moroso 89563

Moroso 89563

wound up being the best gauge for the money, which if I remember a little over $150USD + shipping. It has a very nice big gauge surface, plastic box with foam for traveling purposes and a replaceable glass front. The nice thing is, you can calibrate it and its guaranteed to be .5 psi +/- in ANY condition and from my experience thats good enough.

So anyhow, thats my story. If you really want a gauge thats accurate, it costs money. After buying that gauge, I never had a problem with my tire wear. It was amazing how far off ALL of our gauges were, we all bought that moroso gauge and have all gone quicker because we actually knew what our tire pressures actually are!

tye, you are correct, a $20 gauge is never going to be as accurate as a $150 gauge. Having worked in the petrochemical industry and calibrated my share fair of high pressure gauges, I totally agree with you.

If I was a racer, I would definitely have a much more accurate gauge, as should any racer.

tye, just curious what method did you use to check the accuracy. i have 2 $50-60 and it makes me wonder how accurate they are.

At the race events there is a "master" gauge. Its a $1000 0 - 40 psi oil filled gauge with .05% deviation.

I've never had a $20 or $40 gauge before. All of my previous gauges were $60 and up, PLUS I had a very fancy 0 - 60 psi racing gauge which was still 2psi off compared to the $150 gauge.

Exactly right. I used to carry four tire gauges with me to the AMA races: two Accuguage dial types, a Bluepoint dial type, and some spendy fluid filled gauge one of the riders bought. Thursday and Friday mornings I would grab a scooter and head to the Dunlop truck to check gauges.

I had one gauge that would read close (enough), maybe 2 PSI off. The rest would be four or five psi off. Still usable as long as I wrote on the face of the gauge with a Sharpie "+4" or "-5" or whatever. The spendy fluid filled gauge was the 4psi off gauge.

After a few races I stowed the rest of the gauges and settled on the one Accugauge that was consistently only 2 psi off. I marked the face "+2", meaning the gauge reads 2psi high and that's the gauge I still use today.

The kicker was that depending on where in the country we were, the gauges would get closer or further off. 2 psi at Road Atlanta was 4 psi at Brainard on the same gauge. Laguna was 3 psi on a gauge that was dead on at Loudon.

Makes sense to me: calibrate the gauge you have versus throwing money at the problem.

Then again, notice who was throwing the money.
