Abstract
An asymmetric reinforcement belt structure for a pneumatic tire includes an outer belt and inner belt, each reinforced with a plurality of generally parallel cords. The outer belt has a first portion between the centerlines of the cords and a first surface and a second portion between the centerlines of the cords and a second surface. The first portion has a thickness T1 which is between 110% and 150% of T2. Similarly, the inner belt has a third portion and a fourth portion, with the third portion being between the centerlines of the cords and a third surface and a the fourth portion being between the centerlines of the cords and a fourth surface. The fourth portion has a thickness T4 which is between 50% and 90% of a thickness of the third portion T3. Orienting the cords within the belts in this way separates them slightly more than would be so if the belts were symmetrical.
