    Default Need help with wheels for my new 325/60/18s

    Hey guys I bought some 325/65/18s, , My NNBS 07 silverado has a 2.5 level and a 1.5 zone BL, I would like to buy some 18X9 wheels but need help choosing the wheel offset/backspacing that will work best, any help is appreciated,

    I believe the OEM wheels on the NNBS trucks is 18x8 w/ 31mm offset. As NNBS trucks have boxed fenders, they are not friendly to negative offset. For 18x9 try to stick to something in the +18 to +28 range. If it were me, personally, I'd stick to the lower end of that range (i.e. +18 to +20) to stay close to factory.

    This might help illustrate why:

    Thanks for the info, That chart really helps alot, the wheels im looking at are offered with 0, +14 and +30, offsets, do you think that +14 would work? since it would tuck the wheel in less than say a +18 wheel. thanks again

    +14 is probably alright. Worst case you might have to do some minor trimming.
