Abstract
PURPOSE: To obtain a saving-fuel type pneumatic tire for a large-sized automobile by means of a buffer layer interposed between a breaker and a carcass in such a manner as to be smaller in the stretch resistibility than the breaker which cords having a specified stretch resistibility covered with a rubber of specified 100% modulus are laminated in intersection.
CONSTITUTION: The braker 3 employs two or more layers of rubber-coated cord cloth in which cords with a characteristic value K as expressed by the specific equation exceeding 300kg are coated with a rubber over 30kg/cm2 in 100% modulus and laminated intersecting each other in such a slant arrangement that the cords are at an angle of 20W35° on average to the equator of the tire. A buffer layer 4 made of an organic fiber code whose characteristic value K is by far smaller than that of the breaker 2 is interposed between the breaker 3 and a carcass 3. The buffer layer 4 is larger in the sectional width than the breaker 2 but failing to attain the bead section. This provides the pneumatic tire for a large-sized vehicle with an excellent fuel efficiency.
