The invention relates to the technical field of tire production, and particularly discloses a lining composite part for improving exposed lines in a tire and a tire, the lining composite part comprises an airtight layer, a transition layer and a rubber piece, the airtight layer is attached to the transition layer, the rubber piece is fixed to the attaching face of the transition layer, and the transition layer is attached to the rubber piece. The attaching surface of the transition layer is used for being attached to the interior of a tire, and the rubber piece is arranged between the transition layer and the inner wall of the tire. The problems that in the tire manufacturing process, due to inflation shaping expansion, the interval between tire body cord threads is increased, cord thread rubber materials are insufficient, and butyl rubber permeates into an inner liner can be effectively solved; and the problem of wire exposure in the tire caused by size and quality fluctuation of half parts, too low Mooney v
