That calculator tells me a 107.25 inch diameter tire is needed for 70 mph cruise at 1000 rpm with a 4.56 rear   :smilielol:

Sorry, not much to do and I got a bit punchy. :slap:
Who in their right mind would say

"The science should not stand in the way of this."? 

Science is just observation and hypothesis.  Policy stands in the way.........

Or maybe it protects us. 

I suppose it depends on the specific case.....

Yup, pretty accurate... 4.88s, 28" tire at 60 is 3500 in my car and my 108 trap speed in the 1/4 is at about 6500....
