Accutire MS-4350B Programmable Digital Tire Gauge

I also found it difficult to get a good seal with this gauge. I first tired cutting a piece of rubber to fit, but without proper tools (hollow punches of exactly the right size), I could not get it.

Then I bought a 5/16" o-ring from Ace Hardware. It fit perfectly, but I could not get the gauge to work. Maybe the o-ring was too thick, or too hard.

Then I noticed that the old pencil gauge had a rubber gasket in it. I removed it, and saw that it was about twice as thick as what I needed, so I cut it in half with a sharp scissors. Put it in the Accutire gauge, fit perfectly, and now the Accutire seals with no loss of air. Hey Accutire - are you listening?

I bought 2 of these, one for my father and one for me and both work good. I was concerned about old reviews of this tire gauge but it seems to me that Accutire solved the problem. Sometimes still some air get out so you have to be fast to press the gauge to the tire.

Second one I have owned. Good readings. Lighted. Programmed to pressure in both front and rear tires.Easy to handle

Easy to use and the screen is easy to read. It's a little big for a tire gauge but the size also makes it easier to handle.

I bought two of these gauges. They are easy to use and work great. They appear to be accurate, unless they are both off exactly the same way. By keeping my Toyota Prius tires properly inflated I get at least 10% better gas mileage, so the gauges will pay for themselves soon.
