1. Locate the Spare Tire: The spare tire is usually located under the truck bed. You'll likely need to access it from either a panel in the bed or (less commonly) through a rear access door under the bed.
2. Access the Spare Tire: This is the trickiest part. There's no single answer as the access method varies.
* Under-Bed Panel: Most Hardbodies have a removable panel in the bed floor. Look for fasteners (bolts, screws, or clips) securing this panel. You might need a wrench, screwdriver, or even a pry tool (carefully!) to remove the panel.
* Rear Access Door: Less common, but some models have a hinged door under the bed. Locate this door, usually near the tailgate. It might have a latch or handle.
3. Remove the Spare Tire: Once you've accessed the spare, you'll likely find it held in place by a retaining strap or clamp. Carefully undo the fastener(s) securing this strap. Sometimes there's a winch mechanism; if so, use the crank or handle provided to lower the spare.
4. Lift Out the Spare: Once the retaining mechanism is released, carefully lift out the spare tire. It can be heavy, so be prepared. Have a friend help if necessary.
Important Considerations:
* Tools: You might need basic tools like wrenches, screwdrivers, or pliers.
* Owner's Manual: Check your owner's manual (if you have it). It should contain specific instructions for your model.
* Safety: Be cautious when working under the truck. Use jack stands if necessary for added stability.
* Weight: Spare tires are heavy. Lift with your legs and avoid back strain.
If you can't find the access point, look closely around the truck bed for any panels, doors, or release mechanisms. Pictures of your specific truck bed would help to provide more tailored advice. If all else fails, a local mechanic or Nissan parts specialist might be able to assist.
