What is the purpose of chines on some aircraft nose wheel tires?

Chines on aircraft nose wheel tires serve the specific purpose of deflecting water away from the fuselage during landing and takeoff. Water on the runway can create a hazard, as it may lead to hydroplaning or reduced braking effectiveness. The design of the chines helps to create a channel that directs water away from critical areas of the aircraft, reducing the risk of water being sucked into the engine intakes or affecting other systems. This feature is particularly important for maintaining safety and stability on wet runways. While other options may touch on features that enhance performance or durability in a general sense, the primary purpose of chines is focused specifically on water deflection.
