While higher pressure is good for preventing hydroplaning, it's because the opposite is true. A firmer tire sinks or cuts into the water better, which is why you want to pressure up to prevent hydroplaning.
LOWER pressures make tires more likely to ride over water puddles, causing hydroplaning. But this is also the reason we use lower pressures off road, to keep the tires from sinking more into the mud.
