Okay so I know that I'm getting 17"x8.5" wheels with a 5x5.00 bolt pattern. However, I have no idea what the best offset would be... The wheels I want to get only come with either a -6 or +6 offset on their 17" wheels. Which offset would be best?

* I don't know if it matters but I'm getting LT315/70R17 tires and a 2.5" lift *

Thanks and sorry for the stupid question

 

Backspacing is a much more user friendly term than offset, so you might want to just convert your offset to backspace to help you decide. (negative offset = less backspace = better results for larger tires, but do the conversion)

You can find some backspace recommendations in both of the threads stuck to the top of this modified area.

A chart, though I haven't compared it to doing the math conversions:

so basically the -6 offset would be better?

 

-6 is what you want.

Yeah, it's probably a lot of trouble to open links and read.

+6 = 5" backspace
-6 = 4.5" backspace


One sticky:
The other sticky:

So unless you have fender coverage laws that you need to consider, the 4.5" backspace rims would be the better option.

 

Wouldn't that be +6mm offset would be 4.5" bs and -6mm would be 4" bs on a 8.5" wheel.
