I usually allow 1" on each side of the rim for clearance.
This seems to work with the 35 or 40 series tires I try to run on 20" and 22" wheels.
Of course,... if you try to mount a 275/60-15 tire on a 15x6 wheel you are going to have excessive tire bulge.
My tool gets me really close to what I need.

The real purpose of this thread is to get people to measure their OWN TRUCK or car, themselves.
There is a ton of info on doing this, whether its videos or tools.
