The cold weather came in, and one of my tires on my 2024 dropped a few pounds. I think it might have a really slow leak. I aired it up, restarted the car several times, but the alert won’t go away. The tire is showing the same 33 psi as the others. How do I fix this?
I think the recommended pressure is 35 psi. You probably need to hit that number for the alert to clear. Sometimes, just driving around a bit can make it reset. That’s how it worked with my old car.
33 psi might not be low enough to trigger the system, but the one that dipped below the threshold for the alert might still be stuck. It’s called hysteresis.
Cold weather often causes tire pressure to drop, and one tire always seems to lose more than the others.

Yep, this is the right answer. Fill the tire above 35, and the warning should go away.

If you look at the picture, it shows the alert is only for one tire. I’ll give this a shot though.
@LizCampbell
Once a tire drops below the threshold, the alert won’t clear until it’s filled past 35 psi, no matter what the others show.
@LizCampbell
Same thing happened to me. Just inflate all of them above 35, and it’ll clear.
Pump it up to 35 psi, then take it for a drive. That usually resets it.
It’s the cold weather. Happened to me too. Even after filling it, you might need to drive for a couple of minutes before the alert clears.

Mine didn’t clear, but I only added 34 psi. I think I’ll try adding more.
I used to work in a shop, and this happened often. If filling it and driving doesn’t clear the alert, it might be a faulty tire sensor. A mechanic can check it and see if there’s an error code.
Cold weather causes tire pressure to drop. If the temperature drops by 25°F, tire pressure can go down by about 10%. This might just be physics at play, not a leak.
In the fall, I usually inflate my tires about 10% over the recommended pressure to avoid alerts through the winter.
If the pressure is just a little low, driving for a bit can warm up the tires and raise the pressure enough to clear the warning. But if the sensor or battery in the sensor is failing, you’ll need to have that checked.
I aired it up, restarted the car multiple times, and the alert won’t go away.
Have you been driving it too? The system needs you to drive a little before it updates.

I drove 700 miles. It happened while I was in Texas for Thanksgiving, and the alert never cleared the whole trip home. I’ll try inflating to 35 psi in all tires, and if that doesn’t work, I’ll take it in. Thanks for the tips!
This just happened to me. Cold weather was the cause. I ended up taking it to the dealer, and they sorted it out.
Same issue here a few days ago. One tire dropped to 26 psi because of the cold. I aired it up to 34 psi (I know it should be 35), but the alert didn’t turn off right away. After driving for about 20 minutes, it finally went away.
Take it to a tire shop. They can unmount the tire and check for leaks. They can also inspect the TPMS sensors to make sure they’re working.
If you want to check for leaks yourself, inflate the tire to 36–38 psi, spray it with soapy water, and look for bubbles.
You might also try inflating the tire past 35 psi, deflating it, and then filling it again to the recommended level.
I’m in Colorado, so I always adjust my tire pressure before the temperature drops too much to avoid these alerts.
If nothing else works, disconnect the battery for a few minutes. It’s like restarting your computer.
You don’t need to reset anything. Just drive around, and it’ll eventually clear itself once the TPMS updates. Make sure the pressure is 35 psi or higher when it’s cold.
Also… looks like you need gas.

Haha, you sound just like my late husband. He always kept the tank above half and got on my case if I let it get too low.

That’s funny because I do the opposite. My wife gets nervous because I like to see how far I can go on fumes .
