Abstract
A pneumatic tire comprises: a carcass ply extending between bead portions and including a topping rubber layer, the topping rubber layer facing the inside of the tire and made of a butyl rubber compound containing at least 10 parts by weight of butyl rubber or butyl rubber derivative; and a belt disposed radially outside the carcass in the tread portion, the belt comprising at least one ply of monofilament cords laid at an angle of from 10 to 40 degrees with respect to the circumferential direction of the tire, and each of the monofilament cord consisting of a single filament. The belt further comprises one ply of multifilament cords or one ply of monofilament cords. The height of a bead apex, which is disposed between a carcass ply turnup portion and main portion in each bead portion, can be reduced into a range of from 10 to 20 mm, and in this case, the carcass ply turnup portion is extended radially outwardly beyond the radially outer end of the bead apex so as to adjoin the carcass ply main portion.
