Abstract: A heavy duty radial tire includes at least one radial carcass extending from one bead portion to the other bead portion and using inextensible cords and a belt arranged outwardly of the radial carcass for reinforcing a tread of the tire. The tire comprises, during expanding of the tire from 5% to 100% of a normal inner pressure, a first profile portion (5) expanding radially outwardly in a tread zone, a second profile portion (7) depressing axially inwardly of the tire in a radially outer zone of a sidewall from one end (4) of said tread to a tire maximum width position (6) when filled with the normal inner pressure, and a third profile portion (9) expanding axially outwardly of the tire in a radially inner zone of the sidewall from the tire maximum width position (6) when filled with the normal inner pressure to a parting point (8) of the sidewall from the rim, thereby properly distributing strains occurring in the tire in filling with the normal inner pressure. Moreover, a carcass profile in the radial cross-section of the tire filled with an inner pressure 5% of the normal inner pressure and under no load condition is a composite curve smoothly passing through points R, A and G, and the carcass profile fulfills three relations relative to a maximum distance H of the carcass line C from the bead base line RL with respect to maximum distance deviated from an equilibrium configuration curve N.

Abstract: PROBLEM TO BE SOLVED: To provide a tire particle aggregate which can surely close a damaged section with particles while suppressing a weight increase of a pneumatic tire and the rolling resistance deterioration of the pneumatic tire.
SOLUTION: This tire particle aggregate is an aggregate of a tire having a tread section and a plurality of hollow particles which fill a tire air chamber being divided by the tire and a rim, together with a high pressure gas which exceeds the atmospheric pressure. At a position which corresponds to the tread section, inside in the tire diametrical direction of an inner liner, the aggregate is coated with a laminating member comprising a porous material or a sealant material. The hollow particle has an approximately spherical shape comprising a continuous phase by a resin and independent air bubbles. When the internal pressure of the tire air chamber has decreased, the hollow particle expands when reaching a specified temperature (Ts2).

Abstract: PROBLEM TO BE SOLVED: To provide a tire particle aggregate which suppresses a temperature rise in usual traveling, especially in high-speed traveling, and at the same time, can surely restore the internal pressure of a tire to its original state due to a hollow particle when the tire is damaged.
SOLUTION: This tire particle aggregate 100 is an aggregate of a tire 1 which is fitted on a vehicle, and a plurality of hollow particles 4 being filled together with a high pressure gas which exceeds the atmospheric pressure in a tire air chamber 3 which is divided by the tire 1 and a rim 2. The tire 1 is equipped with a side reinforcing layer 7 which is positioned on a side wall SW, and is constituted of a circumferential reinforcing cord which is arranged in the tire circumferentially. The hollow particle 4 has an approximately spherical shape comprising a continuous phase by a resin and independent air bubbles. When the internal pressure of the tire air chamber 3 decreases, the hollow particle 4 expands when reaching a re-expansion starting temperature (Ts2).

Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire of studless specification equipped with excellent anti-abrasiveness performance without dropping the running performance on ice and snow or causing complication of the sipe. SOLUTION: The pneumatic tire is structured so that blocks are formed by partitioning the tread surface with grooves and sipes 4 are formed extending zigzag or undulately approximately in the tire width direction in the blocks 1 arranged at least at the shoulder parts. The ridges extending in the depth direction of the sipes 4 are inclined uniformly toward the tire equator surface from the tread part to the sipe bottom. COPYRIGHT: (C)2005,JPO&NCIPI
