I checked my tires yesterday just to see what psi they were at (TPS Sensor did NOT go off). The psi was anywhere from 29-30 on all 4 tires. I was wondering what psi these tires will need to be at before the sensor goes off in the car. I know the recommended settings are 35 psi for all, I assumed that it would go off anything lower than that...

 

Anything below 32 PSI.

 

The manual for the 05 says that with the 18" and 19" coupe..it goes off anything below 28

 

That cant be right.

The sticker on the door reccomends 30 PSI!

 

sticker on my door (05 with 19") says 35 on front and rear

 

I don't know, but 28 or lower PSI would be fine. Even a perfect tire loses air at a rate of about 1 psi per month through normal air migration. Tires are designed to carry their full load at many PSI less than the recommended pressure. I think the idea of the low pressure indicator is to inform you of a seriously low pressure condition -- even 20-25 PSI would probably be an adequate floor for that kind of warning.

 

Its actually when air is below a certain number yes, but when its actually loosing at to low of a rate as well.

 

That's what the dealership told me. My sensor went off about a week ago, and they told me that the sensor will go off if it's below 32 PSI.

 

Well. That settles that. Dealers are always right!

 

Case Closed eh...

 

Not always right, but a good resource sometimes.

 

when mine has come on (2 occasions) it has been at 32 psi. I got it checked right after it came on both times and put air in my tires after driving about 1.5 miles.... could 1.5 miles of driving raise the pressure 4psi? i doubt it...

 

Maybe that's my problem. All 4 of my tires were 32 if I remember right and my sensor has been freaking out ever sense it got colder here where I live. I suppose I'll just put more air in and see if that fixes it.

 

Mine has gone off about 7-8 times and a four or five times it's been from a slow leak, bad luck with tires. Every time it went off I checked tire pressure and it was always at 25 psi.

 

i dont have the esm in front of me, but i believe its 28psi
