摘要:
A pneumatic tire having a belt structure includes: a first belt layer; a second belt layer in a radially inner position with respect to the first belt layer, a third belt layer in a radially inner position with respect to the first and second belt layers, each belt layer including a plurality of elongated reinforcing elements disposed at a first, second and third belt angle respectively. The first and second belt angles have an absolute value of 15 to 40 degrees; the second angle is of opposite sign with respect to the first belt angle; and the third belt angle has an absolute value of 40 to 90 degrees and is of opposite sign with respect to the second belt angle. The belt structure also includes a zero degree belt layer placed in a radially outer position with repeat to the first belt layer including elongated reinforcing elements arranged such as to form a belt angle which is substantially zero.
