The cord angle is the angle between the tire’s cords and the centerline of the tread. This angle affects the tire’s ability to flex and resist deformation under load. A higher cord angle provides greater resistance to deformation, while a lower cord angle allows for more flexibility. The cord angle also affects the tire’s rolling resistance, with a higher cord angle resulting in greater resistance. The cord angle is an important factor in tire design and must be carefully considered to ensure the tire performs as intended.
