    Alright everyone... I understand that the back spacing is how far the back mount of the wheel is... I dont quite Understand offset...

    I ordered AR Mojaves, which are 17'' 0 offset and 4.5 backspacing. As far as Im aware they should be fine, not much rubbing. I will be running 285s.

    My question is, I really want to run the KMC rockstars... they are 0 offset and 5'' backspace. Will these fit easily or should I expect rubbing?

    I just remember reading somewhere on this site that its reccomended to get 4.5'' or lower..

    Your guys' help is appreciated as always!

    Backspace to Offset Conversion Chart
    The table below is a quick reference for finding offset, pick the rim width and follow the row over to the backspace of your wheel.

    I already know the Offset, its 0 with 5 '' backspacing. Im just wondering if 0 offset with 5'' backspacing is enough to avoid most rubbing within our trucks with 285s, Note I have 3'' C/Os with 5100s in front and 1.5 AAL with 5125s.. Thanks guys.
