Re: tire pressure vs. computer
Mine's pretty close to my gauge, within about a pound. That's close enough to depend on.
I still check it occasionally just to verify.
I keep my tires at what it tells me on the door frame according to the manual gauge. The tire pressure reading in the Jeep usually reads the same or to the next pound cold since there are no decimal places.
