Abstract: This invention relates to a retreadable tire which contains a non-black colored rubber carcass cushion layer sandwiched between its tire tread and tire casing. The non-black colored rubber carcass cushion layer acts both as an adhesive and transition layer for adhering a cured or uncured tire tread to the cured tire carcass. Such carcass cushion layer also acts as a detectable color indictor for indexing and monitoring a complete removal (e.g. by buffing, abrading, or cutting) of the circumferential rubber tire tread and partial removal of the carcass cushion layer without removing the entire carcass cushion layer.

Abstract: A pneumatic tire having a carcass and a crown region is disclosed, the crown region comprising a crown reinforcement structure and a tread portion with a radially inner side and a tread on its radially outer side. The crown reinforcement structure is located between the tread portion and the carcass and comprises a plurality of adjacent cord reinforced strips. The cord reinforced strips are in direct contact either with the inner side of the tread portion or are separated from the tread portion only by a rubber cushion layer. A process to manufacture such a tire comprises the steps of: (1) preparing an assembly with a carcass, a green tread reinforcing rubberized ply layer applied radially upside of the carcass, and a green tread portion applied onto the green tread reinforcing rubberized ply layer, and (2) transferring the assembly into the pneumatic tire by curing.
