i mocked up the tires for the last time today and got my measurements to send off to jon. i spent a lot of time making sure the tire was square and centered, and double checked my measurements with a little device i made up. he originally just wanted to know the measurement to the tightest spot and that would have been simple with the old ride height and set of tires since it was just in the middle of the quarter lip. but with the new ride height, and because tires dont have square edges between the sidewall and tread, and the tighest spots were at this radius, it was much easier to just mock the tire up.
so with all that said, i plan to give him the exact spot i want the outside of the tire, and im confident he can take that and figure out where that would place the wheel.
here is a pic of how it will sit
