Hydroplaning:

Question

Hydroplaning:

Accepted Answer

B: Is more likely if tire pressure is low.. Hydroplaning can happen at speeds as low as 30 mph, and it does not take much water to cause it. It is more likely to occur if the tire pressure is low or the tread is worn, which means the grooves are not deep enough to carry the water away and ensure the tire's contact with the road.
