So I was trying to impress the cute little brunette. She has a brand new Kia Sportage, has about 5000 miles on it, and the low tire pressure alert appeared on the giant command screen, blocking out actually useful information. She was running 32 instead of 35.
She went to the discount tire store and they put a little air pressure in it, and she still had the alert. I said “no worries! I’m Rick! I can fix anything! Bring it over my house and we’ll check it out.“
I pressured up the one horsepower Sears craftsman air compressor I bought in the 70s, dragged 100ft of hose out, and then used my harbor freight pistol-grip tire filler with gauge, and I brought her up to 36 or 37 pounds cold. The alert disappeared. “Rick is all powerful,” I said, “All your problems are solved!”
So she went 1-2 miles and all the alerts went berserk again. I haven’t asked her for a quote on what she thought of Rick at that point. She came back and I checked it with three of my pressure gauges, which gave three different readings. Then she took out a pressure gauge she’s had for who knows how long. I never saw a pressure gauge that was that clean. I checked it and they were about 40 psi. I’ll let some air out until it was 36 on her gauge. When she left, she was shaking her head.
She went straight to the Kia dealer, and he showed her how to reset the screen.
There are no screens in any of my vehicles. Four of them don’t even have cupholders or pockets.
To regroup for the next time, I went to Harbor freight and I bought a new filler with gauge, and a couple new pressure is very gauges, and a new gauge to swap on to my old tire filler.

When I filled up the F250 tires, the old filler on the left read 30 psi when the new filler on the right read 40 psi. When I checked it with my best old gauge with the black head it read 37 psi, and when I read it with the brand new Silver-head HF gauge it Red 43 psi.
Of course I immediately realized I was not wrong, I was right all along, but I just didn’t use the right piece of cheap or old equipment to get the reading I needed. I mean, air is air, right? I’m going to think about it and then inform her that I was correct all along.
(Actually, that might not be the best plan)
