Default Wheels Question, offset? backspacing? stance?

The wheels I am going to order have zero offset and the backspacing is 4.25 (17x8.5 5x135) (mb wheels v-drive)

I am wondering will this affect my trucks stance? I don't quite understand how the offset or backspacing affects the stance. I plan on running them with duratrac 285 70 17. I've read a lot of posts about the offset having wheels stick out further than stock trucks, I just don't want my tires going inward lol!

That wheel offset will widen your stance slightly. Stock is around +12 offset. I went with -12offset 17x9 with 4.53 backspacing with 315's and widen my stance by about one inch. Hope this helps.

The more negative offset the further they will stick out. Mine are -38

4.25 backspace is not zero offset on a 17 X 8.5. Zero offset would be 4.75 backspacing. Those wheels are -12mm.

This was the information I received from discount tire over the phone, just repeating what they had told me. Thanks for the response though!

I just went to their website and it looks like that rim is in fact zero offset. An 8.5 inch rim is 9.5 inches wide due to the 1/2 inch lip at the front and rear. Centerline of 9.5 = 4.75 backspace and 4.75 frontspace.

If you know the width and offset of your stock rims you can calculate exactly how much different these will fit.

Edit, I"m guessing the stock rim is 7.5 inches wide and -12? So that is 8.5 inches/2 or 4.25 inch centerline. The -12 offset gives your stock rims 4.75 backspace and 3.75 front space. Those MB wheels will fill the inside just like your stockers, but will poke out 1 full inch.

The Vision warriors I am also looking at have a 5.43 backspacing with +18 offset.
Will this offset and backspacing affect how far it sticks out as well?

The first wheel that you asked about was 17 X 8.5 and 0 offset. This Vision you are asking about is 17 X 8.5 with +18mm. So the difference is 18mm.

The Vision will sit further inboard by "about" 3/4 inch compared to the MB. Which is still further outboard than stock by 1/4 inch, but I doubt you will notice. The Vision will fit like stock for the most part.

Thank you everyone. This answered all of my questions. Done on asking questions about wheels for a while
