Correct!
The factory tires are rated at 700 revs per mile (rpmi). That (in theory) is what the ode and speedo are keyed to. BFG's 32.5" dia are spec'ed at 640 revs per mile. That's a 8.6% decrease in actual revs per mile, meaning when you've gone 640 rpmi, the truck thinks that you have gone 8.6% less than a mile or 4826 feet.
If your ode & speed meters were 100% correct to begin with (that's a big if), then when your speedo registers 60mph with 640 rpmi tires, your speed is actually 65.2mph. 70mph on the speedo is the new 76mph!
