    • A rubber composition for a tyre characteristically comprising a diene rubber having an epoxy group, either a monoamine compound or a diamine compound having a structural unit represented by the formula (1):

      (where R¹, R², R³, and R⁴ are each a hydrogen atom or an alkyl group having one to three carbon atoms, and X represents any structural formula) and carbon black, wherein the rubber composition has a dissipation factor at -10°C (tanδ(-10°C)) and a dissipation factor at 70°C (tanδ(70°C)) which satisfy the following expressions: 0. 03 ≦ tanδ(70°C) ≦ 0. 35 W.I.R = {tanδ(-10°C) - tanδc(-10°C) } / tanδc(-10°C) R.I.R = {tanδc(70°C) - tanδ(70°C) } / tanδc(70°C) T.I.R = W.I.R + 2 x (R.I.R) ≧ 0. 3
      where tanδc(-10°C) and tanδc(70°C) are tanδ at -10°C and 70°C of a control rubber composition of the same formulation as the rubber composition except that the control rubber composition includes a diene rubber having no epoxy group and is free of the diamine compound having a structural unit represented by the formula (1).

    • A radial tyre has a cap tread with a tan δ peak temperature of not less than -30°C. The base tread comprises not less than 30 parts of a carbon black having an iodine adsorption number of 30 to 90mg/g and not less than 10 parts of a short fibre oriented in the axial direction. The sidewall comprises not more than 30 parts of the carbon black and not less than 10 parts by weight of the short fibre oriented in the peripheral direction. The bead apex comprises not less than 65 parts by weight of a carbon black which has an iodine adsorption number of 60 to 100mg/g and not less than 20 parts by weight of the short fibre oriented in the axial direction or a direction which crosses the axial direction. This radial tyre is light and has a low energy loss, and can provide an excellent steering stability.
