So I thought It would be interesting to have a thread with our actual tire measurements.

That's weird. When I measured my 265/70/17 BFGs a while back they came out right about where they were supposed to.
Slightly more than 30" on the vehicle at 33psi. Add about
1 inch for the compression of weight and another 2/3rds of an inch for tread wear (16/32 new vs 5or 6/32 in the pic). Total it up and it comes out, if anything, slightly taller than the 31.6 calculated diameter.
