Another gage?
Mostly, my TPMS is dead on with my tire gages. |
The vote seems to be 4 to 1 in favor of the TPMS. The 4 tire pressure monitors agree. The odd man out is your handheld gage.

A while back I bought about six Accu-gage tire pressure gauges and compared them all to each other... and also compared them to about 4 or 5 other old gauges I had laying around. The Accu-gages were all within about 1 psi of each other, quite impressive. The other old less expensive gauges varied by +/- 5 psi... went in the trash. This doesn't mean that the one Accu-Gage you have is dead accurate though. It's quite possible that it's off by 1 or 1.5 psi. When I set my tires cold to exactly 30 psi with any one of my Accu-gage pressure gauges, the DIC will read within 1 psi on all tires, usually dead on. (I'm pretty much at sea level.) You can't make any determinations with just one gauge... unless it's known to be calibrated to perfection.

I compared my Accu-gage with another hand held gage, and they both read very close. So, it could be my TPS?

I live a mile high in Denver, Co. and my tpms always has read 2 to 3 psi less compared to my accu-gage. I set my tires cold based on the accu-gage at 30 psi, and have had perfect tire ware at 11,000 miles.:thumbs:

I don't think the pressure readings of the TPMS can be "calibrated" in the sense of adjusting the pressure readings. All that can be done is to be sure each monitor is linked to the proper position on the car. The TPMS reads whatever it reads, and we are stuck with that.

There is no way you should pick up 4 plus lbs. with just a short drive unless it done in AZ. in August. I assume the drive was under 1 mile. I fine my TPS reading to be within 1 lb of 2 digital and 1 analog guage.

Personally, I'd trust the gauge...

Besides that, I think for any measuring device there has to be a way to calibrate it. It just makes common sense and is a good engineering principle. |
