This is a work in progress. Currently it's only set up for back wheels, using some simple(ish) math. There's been a lot of discussion of what fits, and what doesn't on Supras. So, I made this spreadsheet to show people exactly how the wheel will fit.

It currently takes into account wheel width, tire width, and offset, calculates how the wheel/tire will fit, and compares these values to some pre-determined limits I've come up with based on some research on what fits, and what rubs.
Future things I WILL add:
- Adjustments in calculations for camber
- Calculations for overall diameter of wheel (even if it sticks out, and look ugly, will it still not rub). You know, for people running 15" drag wheels.
- add a table of wheel sizes that most standard tire sizes are measured on, so that the calculated section width is a little more accurate
- modify section width calculations. Right now it's linear, but linear changes in wheel width do not mean linear changes in section width. The current formula works fine for normal usage, but for extreme sizes (super stretched, or super bulged), it's a little inaccurate.
- add a table of people's working wheel/tire combinations, showing how they fit to better demonstrate (and fine-tune) how the physical size limits were found.
