Q

A non-rotating wheel will begin to hydroplane at a (lower/higher) speed than a rotating tire. (Select one and explain WHY)

A

LOWER

Water builds up under non-rotating wheel, increasing the hydroplaning effect.

Q

What is hydroplaning?

A

Tires are separated from the runway by a thin layer of water, resulting in no braking or directional control abilities
