The tire pressure light came on yesterday and the display is reading 29-30 psi on all tires. My question is do I need to take it to the dealer since it has Nitrogen in them? I'm assuming any other place would charge to inflate with Nitrogen.
Tire pressure low, light on

no need, the air we breathe has 78% nitrogen in them. For the most part nitrogen fill is a gimmic. They can't exactly vacuum the air out of new tires to nitrogen fill them.

I have ran Nitrogen in a couple of my previous cars and bikes and never noticed anything different except a green valve cap lol... and when you get a low tire it's a "Pain" if not impossible to add Nitrogen where you need it, so you have to "contaminate" the Nitrogen fill with regular compressed air. Point of running it then is "worthless" unless it's a Drag car.on the track perhaps. When I had mine filled they use an electric pump to vacume air out then fill with the Nitrogen, it was one and the same machine only hooking up to valve stem once to vacume, and fill. Save the Aggregation, run regular compressed air. Also....the purpose of running Nitrogen is to reduce leaking tires and temps...so they claim.
Does that go away? Or will I need to change the sensors?
Is there a way to just shut the stupid thing off altogether??

Just add pressure and call it done.

Have you checked the pressure? If it's 10% lower than the setting the light will turn on. Otherwise it's probably a bad sensor.

If the tires are the correct pressure and you still are getting a low warning, then there is something a miss with the system. The sensors have batteries in them, so over time they will degrade especially if you're in a cold climate.
On a side note...Costco installed free Nitrogen fill stations for customers.

Look at the sticker on the door. That's what it's supposed to be. My 16 runs at 36, so the light would be on at 30.

Yes. There's a sensor inside the rim on the valve stem. Glad you got it fixed!

I'm so used to tires being at 32 psi, I didn't realize these called for higher. My other 3 were at 33/34, so wouldn't set off the sensor, but when that ONE dropped to 30/31....bingo!
Guess they're pretty accurate!!
Thanx again. 🙂
