Always set tire pressure cold with an accurate tire gauge. Don't rely on the TPMS for accuracy. Tire pressure should increase as you drive because tire temperature increases as you drive. When your cold tire pressure is too low, then your tires run hot which hurts gas mileage and tread life. If tire temperature gets too high they can delaminate. I always inflate mine to 37 psi cold, then I don't have to worry about them being too low, especially when ambient air temperature drops.
