    Question about Tire Pressure Sensors

    So I get my 24s taken off today because I am heading off to school in a week. I get the chrome 17s put on at the dealer and I start driving home. A minute into the journey the Check Tire Pressure warning comes on. I turn around and go back to the dealer. they check the pressure and they say that it should be fine now because theres enough air in them, and anyways the sensors sometime fall asleep---i agree with this because sometimes it takes a while for electronics to get kicking again. I get back in and 3 minutes later, the Check Tire Pressure warning comes on. I say screw it and keep driving. Get home, unload my 24s, and check the pressure on all 4 tires.

    FR: 32.5
    RR: 31.5
    LR: 30.5
    LF: 31.5

    This has to be the worst assurance that all tire pressures are equal from a dealer. So i deflate all tires to 30.0. The tire pressure sensor comes on anyways, i Am gonna leave it for a few days and if tehres an issue will go back to the dealer to get new sensors put on.

    Thoughts?

    Re: Question about Tire Pressure Sensors

    Hi - Is it safe to assume that your 17" wheels have the sensors on them? If so, you're tire sensors need to be recalibrated to your SUV. Simply follow the instructions in the owners manual where it refers to tire rotation. When you put your 17's back on, I bet you didn't mach each sensor to its original position as it was when you were running the 24's. Make sense?

    The sensors will only be close, I have sensors on my M5, Corvette's, Grand Cherokee's and if they are within a pound or two that was pretty good, they were only put on cars to detect when pressure would fall below (I believe) 24 lbs as a warning. You will still want to set the tires cold and use a good tire pressure gauge.

    Re: Question about Tire Pressure Sensors

    Correct me if I'm mistaken but the sensors on our SUV's only monitor its assigned wheel, (if you put a new wheel in its place it will set off a warning)and they only go off when a tire has leaked more than 10 psi, right? I assume this because I have to run around letting 10 psi out of each tire when I recalibrate the sensors to their new wheel after a rotation. If I rotate the wheels and do not recalibrate them - then I get the tire pressure warning. That is why i'm thinking that because he switched wheels he'll have to recalibrate. Anyway, this is how it works on our Suburan so i'm assuming that it's the same on the Escalade.

    I know on the Corvette you have to reset/reprogram the sensors if you switch your wheels from driver to passenger side, or they will not read at all, did the dealer reset your sensors with a magnet? In a Grand Cherokee you can change wheels because their tire sensors reset themselves. I think the dealer missed something
