I have an electronic air gauge used to check the air pressure in tires. It says it won't read past 99 psi.

My question is, if I used it to check the tires in a commercial vehicle and the pressure was 100 psi or over, WOULD IT TEAR MY AIR GAUGE UP??

If not, I could still use it to check the tires, and if it didn't read I would know it was at at least 100 psi (where it's supposed to be) if it's below, it should read. :?: :?: :?:

 

i would just buy a truck air gauge. i always have 110 lbs min in my tires. too much air put to gauge can blow seal in it.

 

I have another question on this topic. I like a dial gauge. I have one for my car, and love it. I wanted one for my truck, and finally found one. It looks nice, but it has some problems. The stem is so short that it's impossible to take a reading off inside duals. I can't get it to make a seal, or spin the dial to a position where I can read it. All I do is let more air out every time I persist in the futile effort. On outside duals, it only gives me a reading about half the time, and then it only reads after several seconds.

It has a brass tube with a little brass button on the side. I can't figure out what the brass button is for, and the instructions don't mention it.

I think the thing is probably busted, and probably useless even if it isn't busted, since it won't give me a reading from inside tires.

I'd like to buy a real one that actually works, because I hate the little shoot-out style tire gauges, but I can't find anything like this online, and the one I bought is the first time I've ever seen a dial type pressure gauge in a truckstop.

Also, will a TA take something like this back? I think mine is defective, and if it's not, it's still useless. A big waste of $30 on nothing. Humbug.

 

This is what you need silvan; Milton Industries, model s 909. The button is to release the pressure after reading it.

Actually Mark, the S986 would be best for checking inside duals with aluminum Budds.

It has a straight end which is what you need to get square with the valve stem when working thru those small rim holes.

 

Silvan stated he liked the dial type gauge, which the s909 has. :wink:

There is a digital gauge with the style chuck you mentioned available;

These extensions are also available, which make checking the inner wheels easier. We use these on all our trucks and trailers.
