Tires are subject to extreme conditions, so they must be in good condition to keep you safe on the road. Tires must be replaced after their tread wears down. Even a new tire can be damaged by road debris, potentially causing it a leak or a blowout. You should change any tire whose tread is worn or that has sustained damage as quickly as possible. Fortunately, accessing and removing the spare tire on a Ford Ranger is fairly simple, despite the fact that the tire is located underneath the bed.
Put together the Ranger's two jack handle pieces. Slide one piece onto the end of the second piece until the two pieces snap into place.
Slide the slotted end of the handle through the square opening on the side of the truck's wheel nut wrench until the handle snaps into place.
Remove the lock that covers the spare tire access hole, using the lock's key, if so equipped. (As an option, Rangers are available with a lock to prevent the spare tire from being stolen. The lock is located between the rear bumper and the tailgate.)
Slide the square end of the jack handle through the access slot. The access slot is located between the rear bumper and the tailgate.
Rotate the handle until it engages with the spare tire's lift cable.
Rotate the jack handle with the wheel nut wrench counterclockwise to lower the spare tire to the ground.
Rotate the tire retainer in the centre of the spare tire in a counterclockwise direction until the retainer separates from the tire, then pull the tire from under the truck.
