I added air until 35 psi to the passenger rear and now at the dash it shows 32, at least is not alerting me about low air anymore, I ll leave that way for a couple days and if need will put some more. Thanks everyone for the help on this, seems the issue is they are not showing in the correct order, so some re-pair will be needed Thanks

So far seems the psi I put it’s the same as it’s shown at the dash, as I put with my ryobi 35 and my hand gauge measure the same

I only had this car for a couple months, but the dealer installed new tires so maybe they forget to re-pair I checked those reset re-pair and maybe I’ll get one just to have around as it’s cheap.

I measured today with 42 Fahrenheit outside and all my tires with exception of passenger rear was in 35psi, the rear passenger side was on 25psi. I used a hand gauge I got it last night. In the dash all said are around 34 with the exception of passenger front that still said low showing 24psi. That makes me wonder if the readings are inverted somehow as per my manual reading the rear is the one that should be showing low as per my manual measure have 24 the same amount it show low for the front in the dash. That is something that can happen that is not showing the measurements in the correct tire position on the dash? I’ll put some air to the passenger rear to see if the lower in the dash increase. Can someone recommend a quality Hand Gauge Tire Reader, I have another cars that will be convenient to have one. Thanks

I removed some air and in my ryobi I left on 35psi on the front. I got a new gauge and that one measure the same as my ryobi on the front 34.5 So I know the psi on the tire seems to be ok, I’ll measure again tomorrow as I was driving and maybe affect. On the rear I removed some air and left in 35, on that one in the car now show 34, so seems ok.

When I put air the first time I used the compressor from y garage then after that I was using my ryobi portable cordless inflator that have a digital reader for the psi. When I look to the tire front one doesn’t seems to be like 27psi, so maybe my ryobi is ok when said it have 41. I’ll try one more time putting air but this time I’ll be using my garage compresor with the digital reading again and I’ll be putting 35 in front and back from the passenger side. Thanks

I have a 2020 Sierra Denali and for the last couple days I’ve been unable to put my tires at the sticker door that said that is 35/36psi. All my tires was showing 31, 32, 30, and I decided to put some air because seems was low, on the driver side now shows 36 and 37 that shows is on range, but in the passenger side front shows 27 and rear 39, in front I added 4psi to at least move to 31, and from the rear I removed 4psi to be on 35, but still not showing that, I know that take sometimes or many miles to update. What I’m doing wrong? Maybe the pump I'm using is not the correct one, for example when I put the 4psi in front on my pump measure was showing 37 when I started and 41psi when I finished and in the car still shows 27psi. Never happened to me this before in any of my other cars. Any idea on what I’m doing wrong? Note I live in Massachusetts and its 36 Fahrenheit.

Hello everyone, The tailgate on my 2020 GMC Sierra 1500 Denali was replaced because some dents here and there and because my others emblem where painted black (Plasti Dip) they didn’t install the original ones and instead just give to me so I can paint before install (seems they don’t know you plasti dip when then installed) so now I have the emblems but I’m unable to find any instructions on how to install. So, if anyone with the same truck can take some measurements like where they start and the high for the Denali and Sierra emblem I’ll appreciate, Thanks in advance
