If you truck is at stock ride height with stock wheels, it probably won't make much of a difference. If it's truly 1" wider overall, it's only 1/2" per side. If on the other hand your truck is lowered, it probably will matter, depending on how wide the tires are. If they are skinny wheels and tires, there's a lot of room in the wheel well. But for fat wheels and tires to fit under a lowered truck, the backspacing would need to be increased, moving the centerline of the rim further under the truck. Depending on the size and depth of the rims you want, this may not be an issue other than perhaps needing to have rims built with a custom offset which may cost more than off the shelf items.
