So we also need a set of contact-patch-pix of both tires with typical "real world" load weights. My car is ~2400 lbs. My tires are rated at 1356 lbs per tire at 51 max PSI. That's 5424 lbs max. I would say that with all my crap + my wife equals up to 2800 lbs, or 700 lbs per tire. That's a little over 50% of max lbs per tire.

If we do other calculations, I wonder if we'll get a similar 50% "real world" load per tire, at least for passenger cars that aren't hauling heavy stuff around.
