I think the cantilevered tire "solution/proposal" was created so that
car owners who have discovered the cantilever tire is faster want a
replacement tire that can still have the same tire patch on the ground
if cantilevered tires are removed from the available list. No one wants
to go slower and since the introduction of the cantilevered tire, quite
a few drivers are going faster than they did on the narrower tires. Duh...
I haven't read the entire proposal...my head started hurting...
From past times a way of measuring tire patch was to drive the car
through a patch of flour or similar stuff and measure the impression
left by the tire. Tire pressures had to be what was run that day.
Perhaps simplistic, but it worked.
