hi, i just got a 02 nissan frontier kc and it did not come with an owner manuel and i am wondering how can i take off the spare tire.

The sparetire is located underneath the bed, there is a tools that use to take the spare tire out it is similar as a rod jack handle, when you locate the tools insert it on a hole located on the rear bed edge just above the rear bumper, it looks like a key hole, all the way to the frame slot that holds the spare tire then turn the rod counter clockwise to release the spare tire.
