Abstract

A tread for a tire includes: a first tread zone extending circumferentially, continuously, and entirely around the tire, the first tread zone being formed of a first compound; a second tread zone extending circumferentially, continuously, and entirely around the tire, the second tread zone being formed of a second compound different from the first compound; and a boundary groove axially separating the first tread zone from the second tread zone, the first tread zone, the second tread zone, and the boundary groove entirely forming the tread, the boundary groove having an axial centerline disposed an axial distance from an equatorial plane of the tire. The first tread zone has a first circumferential groove and a sidewall portion defining an intermediate circumferential rib of the first tread zone and a shoulder circumferential rib of the first tread zone.
