Last weekend I rotated my tires for the first time. This tip is for those who have square 4's or the same size tires all around. I have 175's on stock 5.5 inch wheels.
Anyway....
Did the rotation, wheel lug torquing, etc. and took the car out for a ride and noticed right away I had a TPMS light on. I reset it and shortly later it came back on.....
Then I realized the error of my ways.....
Remember after you rotate to deflate the fronts down to 29/30 psi and to inflate the rears up to 36. When I rotated the tires, I swapped front to back on both sides ...no "X" pattern....just front to back. That puts the higher pressure tires on the front (no problem for the TPMS) but also puts the lower pressure tires on the rear, making them underpressured for that wheel position and underpressure for the tire position on the car.
Adjusting the pressures cured the problem and reminded me of what I had to do to .....
There must be individual pickups on each wheel or axle to read the sensors inside the tires otherwise how would the TPM system know where the wheel actually was?
Just a note to those who can rotate and who may encounter this situation.
