Just an FYI:
The tire manufacturer I retired from used to hold a yearly demonstration of new products at its proving ground. Part of this was a demonstration of the principle behind putting new tires on the rear.
They set up 3 identical cars - one with 4 new tires, one with new tires on the rear and shaved to 4/32nds tires on the front, and one with new tires on the front and shaved to 4/32nds on the rear.
The course was a 200 meter diameter circle with a small section of it covered with water, with a large runoff area immediately after. The object was to drive all 3 cars through the water at 45 to 50 mph.
The car with new tires drove through the water without incident. The car with shallow tires on the front, new tires on the rear hydroplaned in the water but exited nose first and could be brought to a stop under control.
The car with new tires on the front and shallow tires on the rear, swapped ends in the water and could not be brought under control under it had stopped.
Over the years, thousands of people experienced this themselves. It was conducted on FWD and RWD, But that’s the kind of thing that stands up very well in court.
