Something happened today to make me doubt the accuracy of the tire gauge that I have been using the past few years. So what brand of tire gauge is a "good" one? How can you check the accuracy of a tire gauge?Thanks for your help.

How can you check the accuracy of a tire gauge?Thanks for your help.I went to the tire shop where I buy all my tires and asked them what gauge they recommended and used.

I've tried several over the years, but the best & most accurate has been a Accutire Model MS-4021B Digital Gauge - I've had one for well over 10 years & just recently ordered another one for $15 direct from the company with free shipping.It reads a range of 5 to 150 PSI in 1/2 lb increments. It works great on single wheels, but not on dual wheels due to the valve stem angles. I use a Acme Truck Digital Angled Dual Foot Tire gauge model A567 for my dually. It reads from 2 to 150 psi in .1 tenth increments.

If there is more than a 2-3% difference, you need to compare the gauges to a tire store's reading to make sure they match.Jim

I've got three or four electronic ones and have compared the readings of them all. They're all pretty close to each other. I use whichever one I pull out of the drawer first. Works for me. I'm not going to worry about a couple psi.

With one gauge you know the pressure. With two you will probably never know the pressure!

That makes no sense. If you have two, and they differ by 10-15 psi, using the defective one would be disastrous.

If I have two that differ by that much I will find a known pressure to check or beg, borrow or steal a third to determine.

Just hope the third one doesn't read right in the middle between the other two. Then you won't know which one to throw away! :)

Not much good for a RV,only goes to 60PSI

I use this one, it is good to 120psi

I use that one to fill my tires but don't drag it out just to check the tire pressure,I use this small and accurate tire gauge,good to 150 PSI Amazon $9.50

I have two of those Accutire thingies that agree with each other, a truck-type digi gauge that reads 3 psi lower and a TPMS that reads 3psi lower still. Which is right?

I asked at a Goodyear dealer about a reference gauge that I could compare against and he said that they just use the ordinary stick type gauges.
