<p>This invention relates generally to tires having treads that have a configuration and/or properties for maintaining hydroplaning performance, dry braking performance and improved wear resistance, and, more specifically, to a tire that has a tread that has a variable sipe density, i.e a higher sipe density in its central portion and a lower sipe density in its shoulder portions, as well as a round crown with a predetermined inflated profile droop. Another embodiment of the present invention further includes the addition of a member that provides more structural stiffness across the crown. of a tire, such that better compromises between hydroplaning, dry braking, and wear performances can be obtained.</p> |
