I need help with backspacing and bolt pattern on some wheels
im planning on getting the Center Line H/T Cast Series 33 Wheels
in a 16.5x9.75 do i need the 5x135mm or 5x5 1/2 bolt pattern and is 4 1/4 the correct backspacing
thanks in advance

The bolt patern you need is the 5x135mm. I have never herd of an F150 that uses a 5x5.5 bolt patern.

The back spacing is all up to your prefrence but with that width of rim I would recommend at least a 5" to 5.5" backspacing. Remember the less backspacing you have the more they will stick out from the wheel well.

 

I do beleive that the minimum back spacing to clear the brakes is four and a half inches. Someone correct me if I am wrong but I remember hearing that.
