Wheel size/width/Offset calculator

Guys I have a 99 Honda accord coupe its lowered
I am getting XXR's 527 18x9.75 +20 Offset
now I am confused which tires to put on 215/35/18s or 225/40/18s?

^ it's a bit difficult to understand how exactly you are confused, if you're not explaining your concerns..

a calculator for this in plain stupid.

I do it in my head.

Use a tape measure

width wheel, OUTER, in mm
divide in half
minus offset

a distance from hub

use #s to pick out new.can use #s many other ways.

Any one know of the top of their head if 16x8 with -38 offset have enough clearance on a 6th gen accord coupe?
