The invention relates to a method for constructing the tread of a tyre, including arranging a plurality of layers of uncured rubber with a layer thickness per layer of between 30 and 500 μm on a base; removing material from the layers for the purpose of arranging a predetermined pattern; and at least partially separately curing each layer. The invention also relates to a device, comprising a preferably cylindrical base and a control configured to perform this method on a base, and to an uncured rubber strip suitable for use in the method.

A method of laminating a vulcanized tire includes providing a vulcanized tire having a circumferential tread and a pair of sidewalls constructed of a base rubber. The method further includes cleaning the circumferential tread, providing a laminate, and forming a plurality of holes in the laminate. The method also includes applying the laminate to at least a portion of one of the circumferential tread and a sidewall of the vulcanized tire. The method further includes applying pressure to the laminate, thereby evacuating air between the laminate and the circumferential tread of the vulcanized tire and curing the laminate.

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.

This device, designed for cutting the grooves of pneumatic tire treads, includes a re-grooving tool having two distal cutting points that creates grooves in the tire treads having two subgrooves. The grooves improve the fuel efficiency of vehicle and the subgrooves improve channeling and clearance of rain, snow, mud, and other hazardous materials on the road.
