I am looking to purchase a 2002 Sport Trac that has 16 inch wheels. In order to safety the vehicle I need good tires. Right now I have a Ford Explorer SUV with 15's on it. Would I be able to put the 15's onto the Sport Trac? Any answers would be greatful. I went ahead and bought the truck, and put the required 16 inch tires as per the sticker on the side of door.
