Offset/Backspacing Confusion

I'm looking at new wheels and seeing different offset/backspacing options and I'm not sure which to choose for my 06 DC.

I'm browsing 17x8 and would probably pair them to a 285/70 17. Currently I have a stock suspension but plan on getting 5100s and an add a leaf or possibly a new leaf pack.

How do I know which offset/backspacing to choose to make sure the tire/rim isn't tucked in too far or bumped out too much?

Anyone running a similar set up that I described above? What offset/backspacing did you choose? How's the fit? Any rubbing or other issues? Pics would help a bunch.

Thanks.

 

I just put 285/75R16 with bilstein 5100 on 4th position. I also put new wheels 16x8 with 4.5 backspace and have zero rub issues In either direction.

 

On an 8" wheel aim for 4" backspacing. 4.5" works but depending on tire and amount of lift you may slightly rub frame. Not a big deal, it won't hurt anything but can be annoying, I have 4.5 backspace and 285s.

3.5" backspacing is a bit more aggressive, going that far you'll not hit frame but will hit body at turn/reverse. 4" is the happy place.

I have pics and more info in this thread

Thanks guys

 

I currently am running 16x7 wheels with +35mm offset (5" BS I think) and just ordered some 16x8 wheels with +0 offset (4.5" BS) to help stick the wheel/tire a little further away from the spindle and frame. I'm running 285/75/16 tires.

 

The Sweet Spot tire and wheel size.

 

@Professional Hand Model that's what I'm hoping. I'll report back when I get them mounted. I'd prefer to not run spacers if possible.

 

Yeah. You’ll probably rub a little on the inside frame with a hard full turn like going into a tight parking space. Other than that no problems. The other option is spacers, which I avoid as well, but lead to another rub problem at the wheel wells.

I have Michelin Defenders which is an awesome tire.

 

I could be totally off, but my hope is that once I adjust the UCA settings and get my caster right I should be okay. I'm going to take the heat gun to the plastic liners and mold them to give more space. I'm also relocating my washer fluid bottle on the passenger side to make more room.
