Can't say I can see this. A stock 225/75r16 on a stock Jeep wheel would not have the same contact patch as a 33x14.50-15 on a 12" wide wheel. or a 38x14.50, or a 54" Bogger.

Try those skinny tires in the soft sand. Won't work. If the skinny tire were the ticket, you would see a lot more of em on comp rock crawlers, trail rigs, and desert racers.

Its not the same patch. Its just the same size patch in square inches. Its physics. You can't escape it. Divide the weight of the vehicle by the psi in the tires and you will know how many square inches of tire is on the ground.

The difference in contact patch shape makes a difference for different vehicles and uses (even though the overall area is the same).

Backspacing may tell you whether a wheel, regardless of width, will fit over your calipers or hit the inside your fenders; but offset really is the more important figure because of it's use in determining the handling via the scrub radius. Just because most Jeep owners ignore it (and then wonder why their vehicles handle so poorly) does not diminish its importance.
