Rim fitting question....... (BackSpacing)

[ZipTiedCoupe]

Ok, I have tried to find the answer using a wheel and offset calculator but i just cant figure it out. me = fail at math.

I have a 15x8 -22 and want the exact same fitment but with a 15x10.

The back space on the 15x8 -22 is 3.6".

So to commodate for the extra 2" would my new back space on the 15x10 be 5.6"?

Any help would be greatly appreciated.

Thank you guys.

but the question is do you still want the same fitment on the "outside" and keeping the same wheel to coilover spacing?

if thats the case, according to my calc on this one site, u need -47 on the 10inch wide wheel

10 +3 fits the same as a 8 -22, for inching width up you add about +12mm for offset.
