AstroAI Heavy Duty Digital Tire Pressure Gauge 0-230 PSI Calibrated to ANSI B40.7 Grade 2A (0.5%) with Backlit LCD & Flashlight, Stainless Steel for Truck RV Car Motorcycle Bike, 2Pack

The gauge is built very well and a descent weight for what it is and does. It's a solid weight. It was purchased for the rear wheels on my 05 Dodge Cummings Dually, but will use it elsewhere too. The gauge works extremely well on both the inner tire which uses the straight on chuck which requires the chuck to be pushed on and the outer tire uses the angled chuck which requires the chuck to be pulled on. Front wheels are no problem. Both chucks seal extremely well. The long metal rod rotates 360 which is very helpful. The LED doesn't stay on very long (as mentioned in other reviews), but you have a task to do so you push/pull, wait a couple of seconds while the chuck is on the valve, then remove the gauge from the valve stem, then look at the screen, no big deal. Screen is well light and the numbers are very clear, regardless of what unit of measurement is used. It measures in tenths of a PSI. I should have purchased this years ago. I have simulators on the rims (front and rear) and I cut out one of the five ovals so I could get my hand in there. You really can't tell much that one of the ovals is trimmed out. I have stock valve stems TR600 1-1/4" long, rather short, but stock. The angle of the chuck and the cut away simulator works great on the outer tire and reaching the inner tire as well. It did not work well until I trimmed out the hand hole opening of the simulator. The simulator adds about 3/8" to 1/2" of thickness and affected the angle of the gauge connection to the valve stem, but no problem with the opening trimmed out. I rely a lot of reviews of a product, so I thought I would return the same. A lot of writing for only a $15 - $20 purchase, but wanted to share my thoughts of the gauge. Again, the chucks seal really well. Just buy it and put is to use.

This tire gage appears to be well made and heavy duty. It seals well to the tire valve, gives accurate reading. Gives tire pressure in 3 different modes, has a night light and turns off automatically. I like the weight and grip of this tire gage. Hope it has a long life.

Well made, accurate gauge. If you have a hard to reach valve stem, this helps a lot. No issues at all.

Very nice, easy to use tire pressure gauge.

Not my 1st time ordering this product and that says a lot about the quality. It works very well on heavy duty vehicles as well as pedestrian vehicles. Super easy to read

Accurate digital reading, at a good price.

So far, I love this new tool. It's so easy to use and read the psi in my tires. I love the digital readings. Great price, fast shipping, shipping updates. Highly recommended so far.

This gage works great. It is long enough that if you have the right angle you don't have to get down to get the reading. The light makes working in the dark much easier.

Easy to take readings. It shows readings in many units.

Pressure gauge is accurate and easy to use. LED screen is easy to read and the long neck chuck avoids the user to have to get down on their knees to check tire pressure's. For proof of accuracy I compared the AstroAI gauge readings against a manual gauge and the pressure readings were the same.

Perfect Gauge

Excelente producto, práctico y exacto en la medición y súper facil cambiar entre libra y bares

Très utile - surtout dans l'obscurité - pour obtenir la pression des pneus et les mesures sont en décimal aussi donc très précis. La raison qui m'empêche d'attribuer 5* c'est l'absence d'une soupape de décharge qui serait la cerise sur le gâteau.
