Abstract
This invention relates generally to treads having a configuration and/or properties for improving or preventing irregular wear on the tread of a tire, and, more specifically, to a tire that has a tread with a gradient of properties that helps to prevent or improve irregular wear, especially suitable for tires that are free rolling such as steer or trailer tires used on trucks.
Claims17
A tire having a tread with tread elements, said tread having at least one element having a gradient of properties so that a system hysteresis of that tread element decreases as the tread element wears and a system rigidity of the tread element stays the same or decreases as the tread element wears.
A tire having a tread with tread elements, said tread having at least one element having a gradient of properties so that an system hysteresis of that tread element decreases as the tread element wears and modulus of the one or more materials that comprise the tread element stays essentially the same.
