A diagram of an aquaplaning tire Two vehicles aquaplaning through large puddles on the road's surface. Aquaplaning or hydroplaning by the tires of a road vehicle, aircraft or other wheeled vehicle occurs when a layer of water builds between the wheels of the vehicle and the road surface, leading to a loss of traction that prevents the vehicle from responding to control inputs.
The poor water clearance of bar grips may limit their performance on very wet mud. With later patterns, such as the NATO, water may be squeezed out from between the blocks, leaving the mud drier and firmer. As the bar grip gives no escape for this water, they may retain a layer of water-lubricated mud like quicksand that remains extremely slippery.
The contributing factors for viscous hydroplaning are a damp or wet pavement, medium to high speed, poor pavement texture, and worn tire tread. If a runway has good microtexture and grooving and the aircraft tires have a good tread design, viscous hydroplaning could be alleviated.(NTSB, p.92) Macrotexture is visible to the naked eye.

Tire tread block shapes, groove configurations, and sipes [citation needed] affect tire noise pattern and traction characteristics. Typically, wide, straight grooves have a low noise level and good water removal. More lateral grooves usually increase traction [citation needed]. Sipes are small grooves that are cut across larger tread elements.
Aircraft tires generally operate at high pressures, up to 200 psi (14 bar; 1,400 kPa) for airliners, [2] and even higher for business jets [citation needed].The main landing gear on the Concorde was typically inflated to 232 psi (16.0 bar), whilst its tail bumper gear tires were as high as 294 psi (20.3 bar).
