If you have wheel loads (and distribution), the actual contact area can be
determined from those weights and the tire pressure. i.e., Contact Area = wheel
load/tire pressure. If you have actual weights, you should be able to
determine the tire widths associated with those weights by observing the typical
tires on the trucks you've weighed.

H-20 and HS-20 axle
load is 32k.
Tire contact area is
a rectangle w/ length in direction of traffic = 10” and tire width =
I'm assuming that this
would work out to Wheel Load = 32,000#/2 = 16,000#, and Tire Pressure =
16,000#/(10")(20") = 80 psi.
because we're using a lesser load for grade slab design for "chicken trucks"
based on typical weigh values, and I want to make sure I got the contact area
