Most New Tire Pressure Gauges are Not Accurate!

JACO, Milton, Merlin, Tiretek, Etenwolf, Longacre, Dewalt, UNCO, Joe’s Racing, Rhino USA, Accu-Gage, AstroAI, Slime, Campbell Hausfeld, Pittsburgh, Vondoir, SKS Germany.

Gauges tested for accuracy at several pressures. The gauges were then exposed to cold and hot temperatures and compared for accuracy while hot and cold.

I reviewed a lot of tire pressure gauges in this review. Here's the list and more details in the video description. A big thanks to everyone who suggested this topic, and I look forward to reading your comments!!

Great test! I work for JOES Racing Products and I'm glad to see our economy gauge performed decent. We also have a pro tire gauge (model 32317) that is about $10 more that has a more accurate gauge head that we recommend for racing. The head is actually made by the same people that make Longacres, but we get the 2.5" head while they get the 2". We also have a digital gauge that is really accurate, and a $1, 200 precision digital gauge that is stupid accurate that gets hand calibrated on a $20, 000 fluke deadweight tester.


When I get into work Monday I'm definitely going to share this video with engineering, product sourcing, and assembly. We are a small family run company of about 30 people and we are always trying to improve!

Suggested video: Best GARDEN SOLAR LIGHTS - those ones that sticks in the ground and automatically lights up at night - light output, waterproof and impact test, can it withstand hail or heavy rain?

I am so glad you bought 2 gauges from each brand. Holy cow the variance!

[WyJosh]

My wife gets upset when I won't buy something until I've seen your tests. You always manage to cover each base. Thanks for great videos!

[pjkentucky]

Project Farm is still the hardest working channel on YouTube. Your videos always pump me up!

[alickilicki]

Protect this man at all costs. I don't buy anything without checking if he's done a video on that product first.

We, the viewers, rated this channel as the Best Channel for rating products.

I ordered an ETENWOLF T300 gauge from Amazon and it came in yesterday. The box and information inside was much better than I expected all the way around. The calibration and certification of accuracy card really surprised me. So much so that I involuntarily blurted out “That’s impressive!”

This is an S-tier Youtube channel. I work in automotive repair, and have found a lot of consumer gauges to be barely usable. Nearly every major retailer is absolutely flooded by overpriced garbage with a few gems here and there. I have one of the gauges you tested and also found it to be inconsistent, but you'd never know it based on the glowing Amazon reviews page. Thanks to your testing, I'll be picking up a couple of Etenwolfs as that level of accuracy for $10 is unprecedented, and we'd never know it without this video.

I hate when anything with USA in the name is made elsewhere.

[gundy]

Your reviews have saved me more than I can afford to donate, but instead of upgrading my tire pressure gauge to that Etenwolf, I'll just give you the $10 to help you keep doing what you're doing. Thanks for your hard work!

I've been watching project farm for years and it is without a doubt *the best review channel on the internet, period.* No fluff, no boloney, no long intros, just the facts presented as objectively as possible.

[RedShotCreation]

You want to know how good this channel is?
Hear me out - im from EU country, never heard about 80% of US brands, and still just watching 100% of Project Farm videos.

This man buys 30 different pressure gauges for unbiased results meanwhile im still using the 99 cent stick gauge i bought in high school. Thanks for the dedication and all the excellent information over the yrs.

I'm an ASE certified suspension tech. My gauge at work, is a $100 napa tire professional gauge and has been repeatedly dead nuts on.
At home, I have the tested Merlin gauge.
Thank you for the time and energy it takes you to make all these videos Todd.

Project Farm is the only YouTube channel that you might want to actually watch at slower than 1X speed to soak it all in vs. other channels that I run at 1.25X, 1.5X, or even higher to cut through unnecessary BS. Great job on the review. You don't know how accurate what you have is until you really know. Thanks!

I.use a Jaco digital gauge for my race tires on my autocross track cars. I've been very happy with it, and when I thought I had a problem with the head, I called the company and left a voicemail. They never called back, instead there was a replacement head in my mailbox a few days later. I had called because of it losing pressure. When I got ready to remove the original head, I discovered that it was coming unthreaded. I tightened it back up and it's worked perfectly for the last two years. It's also never loosened up either. Great tool, and great customer support!

I’ve been only using US-made Milton. I keep one on my motorcycle, however, during the last trip, I had it packed away that I didn’t have access to the cage, and I forgot to check my tires before I headed out. So I just bought a no-name gage at a gas station and checked. I had a little panic because it looked like both my tires were low. I got back home. Got my Milton out. Got the compressor ready. And my tires were absolutely perfect. The no-name gas gauge was about six PSI off, which is dangerous for lower pressure tires.

Can you test ultrasonic cleaners next? The machines themselves, and then degreasers
