Estimating the term…
A pneumatic tire having a tire tread, the tread comprising grooves therein, the grooves forming tread elements, the tread having a radially outer surface and a non-skid tread depth as measured from the radially outer surface of the tread, and a radially innermost surface of the grooves, and one or more sunken grooves located radially inward and below the surface of the unworn tread, the tread comprised of a base tread compound, a radially outer compound, and a radially inner compound, wherein the intersection of the radially outer compound and the radially inner compound is wavy.
A pneumatic tire having a tire tread, the tread comprising one or more grooves and one or more ground engaging tread elements, the tread having a radially outer surface and a non-skid tread depth as measured from the radially outer surface of the tread and a radially innermost surface of the grooves, and one or more sunken grooves located radially inward and below the surface of the unworn tread, the tread comprised of a base tread compound, a radially inner compound, and a radially outer compound wherein the radially outer compound is just below the surface of the tread.
A pneumatic tire having a tire tread, the tread comprising one or more circumferential grooves and one or more ground engaging tread elements, the tread having a radially outer surface and a non-skid tread depth as measured from the radially outer surface of the tread and a radially innermost surface of the grooves, and a sipe positioned on the surface of the tread and a sunken grooves located radially inward of the sipe and below the surface of the unworn tread, the tread comprised of a base tread compound, a radially inner compound, and a radially outer compound wherein the radially outer compound is just below the surface of the tread, wherein the intersection of the radially inner compound and the radially outer compound is wavy.
