Answer
Teresa,

On every vehicle sold in the US, there is a sticker – commonly called the tire placard - that lists the original tire size and the proper pressure for that size.  The placard is usually located on a doorpost or in the glove box – but sometimes it is located in the trunk or on the fuel filler door.

According to Tire Guides, the placard on your vehicle should say the original tires were LT245/75R16's.  If that is so, then you would just be returning the truck to it's original configuration.
