I hit a significant pothole on Friday, at night in the rain, and blew out the FL <30 day old Conti DWS06 . Bummer.


I had the tire replaced, but the low pressure light is still on even though the pressure is equalized with the other tires. I've driven 20+ miles on the new tire. Any suggestions?



EDIT - I did do a bit of research, and what I found said for others the TPMS just went off after replacing wheels/tires after driving. this didn't work for me.

That’s weird, I had my tires replaced also because of a pothole, but I had all my 4 tpms transferred over to a new set of 4 tires. I took it to Firestone and they said they might have to reset it and reprogram them, I didn’t ask if they did do that, but my TPMS light was on after installing my new tires for about 10 minutes then the light turned itself off and it hasn’t came back on since then. Maybe your sensor got messed up from the pothole you hit?

Maybe try inflating higher than normal, 40 psi or so, see if it resets

This^ will generally do it but if the battery is dead in the TPMS it will need to be replaced.

I never got a TPMS light on mine when I replaced the tires with the winter tires. Seems likely that your sensor was busted from hitting the pothole. Any decent tire shop can do a wireless scan on the sensor to see if it's still working. What I do is scan all four and check for unique sensor ID's because sometimes you scan one and it reads the signal from another one and leaves you thinking that corner is OK when it's actually dead.


Can you see the sensor screen on the car at all? Does it show any sensor readings at all? Usually if it's one dead sensor it will still show the other 3, but some cars will hide all the readings if the car tried to relearn the positions and one sensor wouldn't talk.

I haven't tried anything yet since posting this, but I will explain a bit more about my situation -


When the tire was returned to me, I installed it and drove off to let the TPMS register the pressure. Before too long, I got readings from all of the tires. The new tire was inflated to 40PSI, 5 pounds above the 35/36 of the rest of the others. It still blinked orange at me, and sent the low pressure error on the display, and the low pressure dash light was illuminated. When I parked it again, I reduced the pressure to match the other corners and have been driving it like that since. My new tire registers at 35/36 PSI, within 2 PSI of all of the other tires, but I get an error every time i start my car that I have low tire pressure, and that corner blinks orange on the display.

You have a bad TPMS. Who mounted the tires for you the dealer or someone else?

If it was the dealer, take it back and they'll first reset the TPMS or the system and see if its operational. If it's not, they'll replace it.

Usually, the TPMS sensor turns itself off when sitting still after a few minutes of idle. It sounds to me like it's constantly sending a signal back to the car, even when the car is off and has been off for a while. Most likely a damaged TPMS sensor.

I can definitely confirm that if you have low pressure in the tires and you just started up your car that it won't give you the TPMS light and warning. I ran over a nail once, parked the car and the next day, woke up for work with one of the tires below 5 psi. Started up the car and no TPMS lights. I hit 25mph at the end of my block when it rapidly started beeping at me that I had no air pressure in the tire. I honestly didn't even know either that I had no pressure in a tire.
