well, I had hoped to be able to posted a follow up of my success but it wasn't to be.

The cruise control regularly shuts off at 70 mph

the rear tire's circumference is 79.5". the front tire's circumference is 78.5"

which means the rear tire is *larger* than the front by by 1.25%.

next step will be to swap out the front tires with ones providing a 0% differential
and test the cruise control again.
