No flat tire light on my dashboard but there’s a nail on my tire?

As others have said, you don't even have a puncture - the nail head is just stuck in the treads of the tire. You can just pop it out and you would never know the distance.

The light in the car is the tire pressure monitoring system (TPMS), and you'd only get an indication if there was a puncture or if otherwise the tire pressure was low. Since you don't even have a puncture here, there's no reason for the TPMS to give any indication - you have no leak and won't be losing air because of it.

Just get a screwdriver or a pair of pliers and pop the nail out and throw it away. Nothing more is necessary.

Turns out it needed a patch. Now here’s a problem…Prior to the patch there were no lights on. After the patch, the light turned on and it’s still on. Is that normal?

[MrOracle]

The light means the air pressure in the tire is low. If they didn't fill the tire properly, it can light up, or if the patch is leaking. I would take it back and have them look at it.

That nail isn't puncturing the tire. The nail is sideways. Only the head of the nail is stuck in the tread of the tire. It doesn't look like it's even close to puncturing through all the tread and belts.

You can just pull it out and it will be fine. If you want to be safe, take it to a mechanic or auto parts store and have them pull it. They probably won't charge you for it. Or just have a friend or neighbor look at it and pull it.

Do you have self sealing tires? Some tires have a coating that prevents air leakage for awhile when you get a nail etc.

It is designed to get you to shop without having to fix a flat on the road. It typically only lasts for a day or two. The shop may be able to fix the tire with a rubber plug, so you don't have to buy another tire.

If it isn't a run-flat tire then you are just lucky it hasn't started to deflate.

Sometimes, a nail doesn't leak air. So long as the tire holds normal air pressure, your tire pressure indicator on the dash won't display it.

In the picture, it's possible the nail doesn't go all the way through.

In any ca se, regardless of what the pressure indicator says, have the tire serviced... before you have a dangerous blowout.

The flat tire light operates when it detects a low tire pressure. Sometimes when you run over a nail it forms a plug in your tire and the air comes out very slowly. If you wait long enough the light will come on. Or you can pull out the nail with a pair of pliers, tht should do the trick.

It’s not a flat tire sensor, it’s a tire pressure sensor. When you get a puncture in the treads it can almost seal up around the nail and take a while to bleed down. It’s probably still gonna need to be replaced

[Asker]

It’s up for an oil change. I’ll have my dad take it in and have them check the tire too.

Your sensor is broken, and the tire, but I'm sure you know about that one

[Asker]

Broken? How? It’s a 2022 vehicle with less than 4500 miles on it.

[MementoMori777]

It must have broke when the tire popped, looks like you hit that shit at a high speed

[MementoMori777]

It reads tire pressure and tire damage but the thing is still in the tire, and it's not indestructible lol

[MementoMori777]

Wait we trippin, we as in me too cause the sensor won't sense a nail that's stuck between the threads, it only senses damage

[Asker]

So it’s not damaged?

[MementoMori777]

No neither is your tire from the looks of it, unless it's very deep into the threads that it pierced the tire then you should be able to pop the nail right off and it should be fine.

doesn't look like the nail penetrated the tire. just get it out.

[andreasderjuengere]

Perhaps the nail has a self understanding of NOT being a nail... which makes it a trans-nail.

The warning light must be 'woke', so it will say nothing negative :)

[MrOracle]

ROTFLMAO!

[Erron_Black]

it just looks like it got between the teeth.

[Keishio]

You should take it to a mechanic immediately. This is a major problem

[jimmy2]

Get it check out looks like maybe from pic the tires are ok

[douride2]

So is the tire flat?

[In_Trance]

better get that fixed
