Wheel off set question.

[WFO731]

I am going to be getting a new set of rota boost's with a wheel size of 17x7.5, i want to run 235/45/17's, I am wondering what off set i will need, also if i end up going 225/45/17's what off set should i need? All help would be great, thanks guys. Also does anyone know the hub bore size?

The 235's will want an offset of +40 to +45mm. +45 would be close so lean towards the +40. 225's will fit the same offset with no problems. Hub is 67mm.

I just put some 235/45/17's on my 17x8's with a 42mm offset and there is about the thickness of a credit card clearance between the tire and the suspension in the back.
