Wouldn't the optimal efficiency of a tire be contact patch size equals tire size?

Meaning if your vehicle has 185 / 60 / 15 then the patch size should be 185mm. I heard a way to measure this using a simple string around the bottom of the tire and some formulas. I'll dig it up and post it to see if we can prove it true.
