Tire pressure has EVERYTHING to do contact area.

No argument there, but I'm sure you're not assuming that the tires are
grossly over or under inflated. They're probably inflated just about
right, right? The wetness of the lawn has a far greater affect on the
damage the lawn would experience than any amount of over or under
inflation.

Take your car, for example. *We'll use your car instead of my because
mine is sort of messy right now.

Let's say your car weighs 6000 lbs (just a random number).

More unrealistic than random. A 3 ton car? The military Humvee is only
5500 lbs.

The GM web site has this about the 3/4 ton Suburban:
Curb Weight 6447.00

and the Hummer H2:
curb weight (lbs) 6,413
