- Reviewed in the United States on July 27, 2024Size: SingleVerified PurchaseI've had a Milton Tire pressure gauge in the glove box of my car pretty much since I started driving. It has been accurate, reliable, quick to read, and easily makes a good air seal with the valve stem. After decades of use, and banging around in the glove box and the heat of the car it finally started working unreliably. I was very glad to find that same, made in USA model was available, and at a price competitive with cheap Chinese made junk.
I also just bought an AstroAI digital gauge with a tire inflator for my air compressor that is claimed to be very accurate. That gauge and this Milton read about the same, to the level of accuracy that can be read with this gauge they read the same, confirming the accuracy.
If this gauge lasts anywhere near as long as the first one I had it will outlive me.
I have an older digital tire gauge in the glove box of another vehicle that has lasted for years. That gauge is very accurate, but it requires several seconds to get a reading, and doesn't seal to the valve stem particularly well making it a bit of a pain to get an accurate reading. This Milton is much faster to read.
Just buy this tire gauge!

- Reviewed in the United States on April 1, 2022Size: SingleVerified PurchaseThis is a well-built tire gauge with an all-metal housing. It is made in the USA. It is easy to use and accurate. As long as you don't intentionally abuse it, it should last for years. It's about the size of a pen so it is easily stored and if you drop it, just pick it up because it will still work. You should regularly check your tires and not assume the sensor in your car works perfectly or you eye-balling your tires is an accurate gauge.
To be fair, you could easily get two for the same price or less (and with free plastic valve stem caps!) but they would be made of cheap, scratched, chrome-looking plastic made in China. They probably won't be accurate and they will fall apart after a few uses. If you drop it, forget it because it just snapped in two or parts flew everywhere. So, in the end you will end up paying more because you probably broke the back-up gauge already. Save yourself the drama and just get this first.
- Reviewed in the United States on August 29, 2024Size: SingleVerified PurchaseI’ve used Milton pneumatic tools all my life. I sold them for 15 years at the auto supply store I worked at. This Milton air pressure tire gauge is easy to use. It’s very quick and holds pressure well. Fits in your shirt pocket, glove box or console. Pressures are 5 to 50lb. Perfect for cars, trucks, lawn mowers, tractors. If it ever fails Milton also has the prongs and parts to repair it. You do’nt have to believe me, ask any mechanic what the best air products.
