I notice that the readings on my sensor show that all tires, except the spare, are within +- 1 pound of each other. They sometimes are all at the same pressure when driving, and sometimes one is 1 pound more than the others or another is 1 pound less. Is that close enough?
I can tell that the first position is always the spare (it doesn't change as much or at all when the car is being driven.) I understand from previous threads that there is no particular order for the other tires. However, do the same tires display in the same order every time. The reason I am asking is that if I find out the order, by trial and error, then I will know which tire is higher or lower, and I can go directly to that tire instead of measuring all the tires to find out.

My spare is at 37 psi cold (meaning about 50 F.) and goes up to 38 on a nice northern California day - like today. On a real scorcher as we had a couple of weeks ago, it goes up to 40 psi. The tires are at 34 cold and go up to 38 or 39 after driving on the freeways for 20 minutes.

I have about 8K miles on the car.

Thanks.

 

no, the order won't change when you change the wheels around, so it's not going to be easy for you to pinpoint

the psi sounds about right. imho between 32-34 is ok.

 

Thanks, Henry.

 

Is there an option inside the car to check the pressure of each tire?

 

? just press on the DISP button on the steering wheel several times until you see the screen that tells you all the psi?
