Question about backspacing

If I were to put LT/315/75/R16 Tires on my truck...would less backspacing mean that they are less likely to rub the frame of the truck. My wheels I think are 4.5 in backspacing

What is the difference between backspacing and the offset?

Thanks

Backspace is the distance from the wheel lip to the mounting surface.

Offset is the difference, usually in mm, the wheel mounting surface if from the center of the rim.

Yes, less backspace on the wheels will move the tire away from the frame, it will also add more stress to components like wheel bearings.

and make your tire more prone to rubbing things like your bumper, inner fender and fender
