A tireincludes: a pair of beads; a carcass plyhaving a ply main bodyand turned-up portions; and a pair of fillersthat are located outward of the turned-up portionsin the axial direction and that include metal cords. In a radial direction, a first endof each filleris located inward of a bead base line, and a second endof each filleris located between an endof the turned-up portionand the bead base line. A recessis provided on a zone of each side surfaceof the tirebetween a maximum width position and the endof the turned-up portion

Heavy duty pneumatic tire

A radio tag-mounting member for use in a pneumatic tire having a sponge material fixed to the pneumatic tire at a rim-mounted side surface thereof or/and a rim at a tire-mounted side surface thereof; and a radio tag having a portion for detecting an internal state of the pneumatic tire or/and a portion for recording identifying information of the pneumatic tire. The radio tag is inserted into and fixedly accommodated in an accommodating portion formed in the sponge material as a concavity or as a slit-shaped notch; or the radio tag is fixed to a surface of the sponge material.

A pneumatic tire which includes a tie bar in a lateral groove disposed in a block array, the tie bar connecting adjacent blocks in a circumferential direction through the lateral groove. The tie bar is formed with a sipeing having a zigzag portion, the zigzag portion extending in a zigzag manner in a direction of a groove centerline of the lateral groove. The sipeing is a three-dimensional sipeing in which a sipeing wall surface is repeatedly recessed and projected, three-dimensionally.

A steel cord for reinforcing a high polymer material has a core formed by twisting three steel core filaments having a mutually equal diameter of 0.1 to 0.35 mm, and at least one sheath formed by twisting a plurality of steel sheath filaments having a mutually equal diameter of 0.1 to 0.35 mm and arranged around the core. The three core filaments are composed of one or two waving steel filaments each having waved portions apart from a longitudinal center line thereof, and an unwaving steel filament as a remainder. The clearances (T) between the waving steel filament and the unwaving steel filament are in a range of 0.15 to 0.6 times the diameter of the steel core filament. A sum total (M) of a mean void (m) between adjoining steel sheath filaments in each sheath is in a range of 5 to 35% of a sum total (N) of a mean center distance (n) between adjoining steel sheath filaments in each sheath.

A tire and rim combination comprising a carcass turned up around bead cores from the axially inside to the outside thereof to form turned up portions; bead filler ply disposed between the carcass and each bead core and having an axially inner portion and an outer portion; and a chafer having a main portion extending along the bottom of the bead and an outside portion extending radially outwardly from the main portion along the axially outside the carcass turned up portion,
