Tread depth plays a large role in hydroplaning. So does aspect ratio. Aspect ratio is what determines how much time the tire has in order to scatter X amount of water before the tire's load-bearing contact patch moves over it.
Those large diameter tires are not actually that bad at resisting hydroplaning. If they had the same diameter, but were wider, they would be worse. However, the increase in diameter changes everything. With oversized off-road tires, my truck hydroplanes dramatically less than it did with stock-sized tires that had very small tread depth.
Hydroplaning is also less of an issue when you are in a vehicle with a long wheelbase. They are far more stable in winter. Even if there is a puddle big enough to cause me to hydroplane, only one or two of my wheels will hydroplane at a time when I am in my off road truck.
In comparison, my toyota corolla is terrifying to drive in the winter here in wisconsin. I have good tires on it, but it is very unstable. Even a small puddle will cause all 4 tires to hydroplane, and they do it at the same time. Then, it has a very short wheelbase. It makes it far less stable.
A lighter vehicle with narrow tires and low tread depth will hydroplane at a much lower speed than a heavier vehicle with wide tires and deep tread.

My corolla does one single thing better than my pickup equipped with off road tires. That one single thing that it does better is fuel mileage.
You city commuters should talk less about trucks, considering the fact that you don't know anything about trucks or engineering.
