Tire pressure dash reading.

[stinger92557]

Rear right tire pressure is 39psi. Inside the car the dash reading is 31 psi.
3 other tires measure correctly. Anyone else have this issue?

Mine is the opposite. Set the tires to the correct pressure as per the plate on the door sill and the interior readout shows appx 4psi higher than actual (for all four tires)

TPMS is one of the best things ever and perhaps one of the most annoying. At least this Kia will give you some clue as to which tire is low, all 4 of my others only show low tire pressure, you get to figure out which one is low. Add that to your list of things the dealership needs to address. Bitch enough about it and make them give you a free oil change.

Mine reads high as well. Is there a way to adjust the sensor or will the dealer replace it? To me this is dangerous since they are nearly 15% - 20% off.

Guess that I need to find the readout - interesting that I've not encountered it yet...

I get different readings every day. Sometimes 38, then 36, then 37... can't trust them.

That's kinda bad right? Isn't the pressure warning light linked to this sensor? Never had this issue with my other cars..

No it’s not. A tire can change 2psi just based on ambient temperature. Also cold tires vs warm tires (after being driven on) can be more than 2psi different.

Saying you have seen 36, 37, and 38 PSI at different times is totally normal.

ah yes of course, I am not panicking. Just kind of jokingly said how it varies. Plus, being 1-2 psi off isn't that big of a deal, unless you are in a racing scenario, in which 'air' isn't going to be that stable anyway.

How do you know the car is reading high and your gauge is accurate? Can you check against another vehicle? Mine seem to be pretty close to my other vehicles and against my gauge.

Okay, BIG Bonehead here... After searching the manual, fiddling with the display menu, while the Tire Pressure seems to show up on my display sometimes (not sure when, but I've seen it), how do I ACCESS it to see what the pressures are at?

NOTE: Stinger GT, AWD w/DriveWise... Can't figure out how to access the menu, or is it only displayed at startup or?... Can't seem to access the Tire Pressure info for the life of me. Ugh...

 

[Stinger GT SS]

You have to be driving the car to check the pressures.

 

[Waynerm002]

I use my gauge to test the tire pressure. I noticed on my Optima since the tire change, it reads differently from what the gauge is telling me. I’ve tested it with 2 digital units and a manual version just to make sure. I go by what’s at the wheel when I put air in.

Okay thanks. So when I'm driving, what then do I do? What menu? Can't find it anywhere... Hmmm...

Press the 'pages' button once, it'll take you to the tire pressure screen.

Thanks! I'll try it out!

Strange, mine's been spot-on. Overnight cold, I inflate to 36, flip the display for tire pressures, drive past 35MPH and each tire pressure pops up at 36. However, what I have noticed is more down to physics: the tire pressures start to increase very unevenly until they all ready operating temperatures around 38-40psi. What I mean by physics is a few things: the weight distribution is not perfectly centered between the tires, so even though the car is 52/48 front to back, the left to right may be different; if your drive has more right turns than left, your driver's side tires will start heating up first, etc. However, I've never seen a car where the tires heat up at such rapidly different paces until they all reach operational temperature. The vehicle seems to inherently have a little more weight on the passenger side than the driver's side (which makes sense when you add a driver) from what I can surmise observing my tire pressures as they heat up.

 

[MikeJr74]

Thanks for this thread. I stopped by the local tire center and had them check my tire pressures. The TPMS and their digital gauge matched exactly.

 

[MerlintheMad]

Since I put on new tires (and discombobulated my TPMS, naturally), they have read pretty consistently low by three to four pounds. If consistency remains, I can adjust what I see to reality: e.g. 34 front means 38 psi actual; I know this because a tire gauge at the wheel tells me what the real psi is.

 

[Waynerm002]

Now, that’s a big discrepancy. If you are paying for TPMS service, this shouldn’t happen if they are adjusting them during the “service”. Which brings back my question, what are we paying for if the system can be that much off. Merlin, you just had your tires installed, I would ask them to fix that or explain why the difference since the change.
