From the Dunlop Aviation Tyre manual:-
3.3.1.9. Chined Tyres
Certain tyres for nose wheel application incorporate a flange or chine at the shoulder buttress. The chine is designed to deflect water displaced by the tyre tread and reduce the hazard of water ingestion into the intake of rear engine aircraft when operating from a very wet runway.
