See Tire Pressure on page 10‑51 and Vehicle Load Limits on page 9‑27 for information regarding proper tire inflation and loading your vehicle. For instruction on how to remove, install or store a spare tire, see Tire Changing (H3T) on page 10‑66 or Tire Changing (H3) on page 10‑75. 7. Lower the jack by turning the lug wrench counterclockwise. Keep lowering the jack until the spare tire slides off the jack.
