My truck had the 16x7 stock wheels on it, with 265/75r16s.
I bought 16x8 Vision Warriors (current wheels) with 0mm offset, which also makes an even backspace, so the mounting center of the wheel is directly in the middle of the rim, wheels are always 1" wider than what it says, the bead is 8", but the outer lips come to an extra inch, so really, my wheels are like 16x9s, 16x9s are like 16x10s, and so on, anyways, so 4.5" backspace.
Being a 16x8 with a 4.5 inch backspace, my wheels do stick out an ass hair farther than the fender lip. Enough to make my 3" body lift and 2" block lift look
not so retarded with 265s..
The ones your looking at have a 4" backspace, so they will stick out an extra half inch from the body than mine.
Backspace is the distance from the back of the mounting center of your wheel, to the outside bead of the inside of your wheel. So if you took the wheel off your truck, put it face down on the ground, and measured the distance from the mounting center of the back of the wheel to outer bead on the inside of the wheel, that's your backspacing.
Offset, harder to explain, it goes by millimeters (mm), mine being 0mm, have no offset, so the backspacing is unaltered.
- A Negative offset means the middle of the wheel is deeper in the rim, so the more negative of an offset, the less backspacing.
- A Positive offset means the middle of the wheel is shallower in the rim, so there is more backspacing.
Too high of a positive offset can quite possibly make the inside of your tire rub on the frame.
Too high of a negative offset can be bad for your wheel studs, or on the front can tear up the body when turned full lock, and it's stressful on ball joints and tie rods.
Too high or too low of a backspacing can be bad, if you think about it, if your wheel is super deep, the weight of your vehicle is resting on only 1 side of a wheel, instead of a 0mm offset where all the weight is resting right in the middle of the wheel.
Once again, some bits are harder to explain without using my hands as a reference, like most people do
