ABSTRACT:
A pneumatic tire having tread grooves and tread-ground contact areas separated from each other by the grooves is disclosed. The tread-ground contact area has an outwardly projected edge and is faced towards the tread grooves. That part of said outwardly projected edge which is located nearest the crown center of the tire has at its tip a minimum rubber thickness, thinner than a standard rubber thickness of the tread-ground contact area with the rubber thickness gradually decreasing towards the tip of the outwardly projecting edge. The tire has an improved uneven wear resistance, resulting in greater comfort, reduced vibration and noise and improved durability.
