    Have a quick question for NNBS owners, and all other smart people.

    What is the backspacing on the stock, steel rims? i know they are 17x7.5, but what is the bs? is it 4.5? I appreciate all the help.

    I know on an '07 Tahoe you need like a 40mm offset vs the 12mm offset for the older style. I think that equals like 6.75" BS? That is about all I know.
    Gone, but not forgotten!

    The mm to inches conversion is 1 mm for every .03937 inches... I know the alloy 17" have a 31mm or a 1.25"... Since you have the steel rims, it might be different...
