Tires, Wheels and Loading Sensor position following tire rotation Sensor 1: 50 psi Sensor 2: 50 psi Sensor 3: 80 psi Sensor 4: 80 psi Pressure adjustment without the required TPMS reset procedure Sensor 1: 80 psi Sensor 2: 80 psi Sensor 3: 50 psi Sensor 4: 50 psi In this situation, the TPMS warning light will come on. If the TPMS reset procedure is not performed after tire rotation and air pressure adjustment, the TPMS telltale may illuminate for a false low tire pressure condition. As in this example, the rear tires rotated to the front and properly inflated to 50 psi (345 kPa) for the front axle would falsely illuminate the low tire warning indicator as they are still trained for the rear positions which require 80 psi (552 kPa). 234 2008 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus)
