Alan, you can achieve the same TOTAL AREA footprint with narrower tires AT THE SAME PRESSURES. The problem will be the SHAPE of that footprint (contact patch). The wider tire offers more lateral grip, where the contact patch is wider from side-to-side -- better for cornering, not as good for drag racing!
The other element is this: with a wider tire, one can generally run LOWER pressures, further adding to the area of the contact patch. Physics: The PSI can be slightly lower because the VOLUME of the air inside the tire is greater.
I know I should have let you gentlemen figure this out on your own, but I couldn't resist.

Still not with you Ed. Willing to listen to your reasoning though. When I run wider tires on the front of my car (same compound and hot pressures) I get noticeably more front grip laterally AND longitudinally (under braking). If a narrower tire/contact patch was better for drag racing, maybe someone should tell this guy:

He clearly doesn't get it.
