How to Change a Tire on a QX4

Save

Changing a flat tire on your Infiniti QX4 is an important skill to have. The tools and spare tire are stored in the car so you have them at hand. The QX4 is equipped with a full-size spare tire, giving you time drive to a service station or tire-repair shop and either replace your flat tire or have the necessary repair done. Find a safe place to change the tire if possible. While you can change it on the side of the road, this is not very safe and should be avoided if possible.

Things You'll Need

  • Tool kit
  • Spare tire
  • Park your QX4 on a smooth, flat surface and set the parking brake. Lift the rear-seat base from the back edge and locate the jack and tool kit under the seat.

  • Remove the jack, lug wrench and jack rod from under the seat, then go to the rear of the car. Open the lift gate and locate the hole in the body just above the bumper. Insert the jack rod and place the lug wrench on the jack rod by sliding the rod into the hole in the wrench handle.

  • Spin the jack handle counterclockwise and lower the spare tire to the ground. Remove the lift cable from the center of the rim on the spare tire, then slide the tire out from under the rear of the car.

  • Move to the flat tire and loosen the lug nuts using the lug wrench. Do not remove the nuts yet. Locate the jacking points under the car. On the front that is under the frame rail just behind the axle, on the rear it is under the axle.

  • Position the jack under the car, attach the jack rod to the jack, then install the lug wrench on the rod, sliding the rod into the hole in the lug wrench. Turn the jack handle clockwise to lift the car until the tire is off the ground.

  • Remove the lug nuts then remove the flat tire from the car. Install the spare tire on the car and screw on the lug nuts. Lower the jack and remove it from under the car. Tighten the lug nuts with the lug wrench.

  • Place the spare tire under the car and install the lift cable into the center hole of the tire. Insert the jack rod into the hole in the back of the car and, using the lug wrench, turn the jack rod clockwise until the tire is completely under the rear of the car.

  • Place the jack, jack rod and lug wrench into the storage area under the rear seat and push the seat base down over the compartment.
