Okay, two things. First, since you already have the wheels and tires, are you sure the bolt pattern is correct and the correct offset? I attached a diagram below that will help with this.
Second, the difference in circumference may be a little too much to leave it as stock. The difference is about 8 and a half inches. This means it is 4 inches on both sides.
So I would start with bolting them on the truck and checking the clearance in the wheel well area. If the tire is close to the fender liner then you are going to have to lift the truck. Then turn the wheel lock to lock and see if the tire touches the fender or frame rail. If it does then you are going to have to use a spacer as well.
Let me know if you have questions on this.
