To put 5-lug wheels on a 4-lug vehicle (or vice-versa), you need to change the wheels themselves. You must find wheels with the correct 4-bolt pattern (PCD) for your Ford Ranger. The size and offset of the wheels should also be appropriate for your vehicle to ensure proper fitment and avoid rubbing. Check your Ford Ranger's owner's manual or a reputable tire/wheel retailer to determine the correct bolt pattern and other specifications for your vehicle.
