Definitions

  • This invention relates generally to a tire. More specifically, this invention relates to tires for heavy commercial vehicles especially tires for truck and trailers involved in regional or long haul transportation of goods.
  • the wear life of the tread can be improved by using tread rubber compound that are more wear resistant or by providing for a thicker tread. These moves, however, typically result in an increase in rolling resistance. In turn, rolling resistance is known to be improved by using rubber compounds which are less hysteretic but such compounds are generally less wear resistant.
  • the "radial" direction is any direction in any plane that contains the axis of rotation of the tire.
  • the "lateral”, “transverse” or “axial” direction is along the tire width and is parallel to the axis of rotation of the tire.
  • the “circumferential” or “longitudinal” direction is at right angle with radial and axial directions.
  • tread element is any type or shape of a structural feature found in the tread that contacts the ground. Examples of tread elements include tread blocks and tread ribs.
  • a "rib” is a tread element that runs substantially in the longitudinal direction of the tire and is not interrupted by any grooves that run in a substantially lateral direction or any other grooves oblique thereto.
  • phr is "parts per hundred parts of rubber by weight” and is a common measurement in the art wherein components of a rubber composition are measured relative to the total weight of rubber in the composition, i.e., parts by weight of the component per 100 parts by weight of the total rubber(s) in the composition.
  • elastomer and rubber are synonymous terms.
  • based upon is a term recognizing that embodiments of the present invention are made of vulcanized or cured rubber compositions that were, at the time of their assembly, uncured.
  • the cured rubber composition is therefore "based upon” the uncured rubber composition.
  • the cross-linked rubber composition is based upon or comprises the constituents of the cross -linkable rubber composition.
  • the invention provides for a heavy truck tire having a sub-casing, a belt package and a rubber tread, the tread extending axially form a first tread edge to a second tread edge over a rolling tread width, the tread comprising a shoulder zone adjacent to each of said first and second edges and a center zone separating the two shoulder zones, each shoulder zone comprising a radially lower shoulder layer and a radially upper shoulder layer, the upper shoulder layer being intended to come into contact with the ground and the lower shoulder layer being interposed between the belt package and the upper shoulder layer, the upper shoulder layer consisting of an upper shoulder rubber compound, the lower shoulder layer consisting of a lower shoulder rubber compound being different from the upper shoulder rubber compound, wherein: the upper shoulder layer extends a distance LI from a tread edge point axially inward, the distance LI being greater than 15% and less than 40% of the rolling tread width;
  • the upper shoulder layer has a thickness of between 70% and 130% of the tread depth over at least 80% of the distance LI;
  • FIG. 9 is a partial section view of a heavy truck tire according to another embodiment.
