i got my new tires installed today at a McLaren dealership. they are very well versed and careful so i can't imagine they did something to the sensors. when i took off, a few miles down the road the center gauge went red. i knew the tires were ok so i reset it via the steering wheel. well, it kept doing it.

when i got home, i checked the pressures and the fronts were at 39.5 and the rears at 37. would that disparity be enough to set it off? it doesn't seem to be a case where the sensors are not synched but who knows.

i just adjusted the pressures according to the car specs with the same pressure all the way around and i'm going to take it for a drive after a steering wheel reset.

is there any other reason this would be happening??

 

update...so i set the pressures to a uniform setting as per the fuel door recommendation, reset the jawn and drove about 20 miles. no warnings yet. how strange.
