Tire Pressure Tango

oops, wrong tango...

I was at the dealer for a brake problem today. Asked them to check tire pressure; specs = 35 psi. They said tire pressure was fine.

While driving away I turned on the tire pressure display. One tire was at 29, the others at 30. I figured, drive around a little, maybe it'll come up. The highest any of them got was 31.

So I looked around for a gas station with an air compressor, but couldn't find one. So I went to a tire shop and asked if they'd fill the tires to 35 psi for me. No problem. They were very nice.

Was driving around on other errands, and after a time I remembered, and checked the display again. 30-31! WTH? I thought, hm, maybe there is something wrong with the computer that creates the display. The guy at the tire shop even had a gauge on his air compressor hose.

So I went to an auto parts store and bought a tire gauge. Checked the psi when I got home. 30!!

Does anyone have any idea WTH could be going on with my tires?

Boy, hard to say. Tire gauges are notoriously inaccurate. BlueJazz Nov 2014 #1
