Tire pressure monitoring...

[LoveBunny]

I didn't add any air today though. I just checked the pressure and discovered that basically the 27 my dad told me was just him forgetting what it had been. The message I got that it was still acquiring the pressures has gone away and the stupid -4 warning came back on, so I guess I'll bring the dang car in tomorrow morning.

The dealer has informed me that I was supposed to have 36 in the front tires and 39 in the back. I'm not sure how I was supposed to know that since the door panel says 32 and 37, but apparently that was the problem. I haven't picked it up yet, but I'm sure they'll probably charge and arm and a leg to put some air in my tires.

Hey LB, my bet is that since those wheels (those are 997 Turbo wheels in 19") did not come on your car, the sticker in the drivers door jamb my be incorrect. I have 19" Carrera Classics and my sticker also says 32/37.

The sticker says 19" wheels, so I assumed that it was correct. Oh, well, at least now I know.

Luckily I didn't get charged to find all this out.

The explanation I got from the lady at the dealer is that the computer is set at 36/39 so that's what it has to be. This makes no sense to me. I don't understand why what a computer is set at determines what amount of pressure a manual guage should read on my tire. Maybe I just didn't understand her explanation. I was really tired and recovering from a migraine.

Yours is probably set higher because you have the 19" TT wheels which I assume are wider than 19" CC's and would require afew more PSI to keep the tires from riding on there sidewalls.. just enough so that center of the tire protrudes out more and edges make even contact with the road. When you have too little PSI the center of the tire tread will colapse slightly and the sidewalls will take the grunt of the vehicle weight against the pavement.

so maybe what is listed in my door panel is for 19" wheels but not for my specific 19" wheels? i know it does say 19" so that's why I thought it was what I would need.
