Do note that the "contact patch width" ("c.p." in my table) obtained from the Tire Rack site is the thread
WIDTH, not contact patch
AREA 
.
The shape of the thread cross section as it is molded (straight or angled inward) can have a drastic impact on the width of the thread in contact with the road (contact patch width).
