I had a similar concern myself last year before rotating my tires. There was no problem and no extra steps required. Also I tested my sensors threshold and determined that the low tire pressure light will come on within 500 feet if any tire is 28 psi or lower. It automatically cleared itself within 500 feet of driving when I refilled to 35 psi. Remeber... our explorer tire pressure systems do not differentiate which tire is low, just that A tire is low. Therefore no problem with rotation.
