I have just bought a set of AR-23 in a 16x8 with 4.5" BS. The stock wheels are 16x8 and the 285 75 16 BFG All Terrains rub on the right lower control arm at full lock. Barely. Would anyone know what the OEM backspacing is? I am trying to discover what it is to see if I need a wheelspacer or not, and if I do, how thick.

Any help is appreciated.

Bump. I really need this info and the Stealership does not have it.

TIA

 

I just bought some aluminum wheels off a 2001 2500, the backspacing is 6.25"

 

Wow. Thats a huge number. The tires certainly wont touch the control arms anymore. Thanks.
