<p>A pneumatic tire having an excellent cut resistance comprises an annular crown portion (15) having a tread (16), a pair of side portions (18) extending from the crown portion, a pair of bead portions (11) located at the respective ends of the side portions remote from the crown portion, a carcass layer (3) composed of at least one rubberized cord ply toroidally extending between the bead portions, and a liner layer (5) disposed inside and adjacent the carcass layer.</p><p>In one tire according to the invention, for intercepting crack growth from the outside of the tire, a fault surface (4) having an extremely low adhesion is arranged in the liner layer at at least a part of the region extending between the bead portions.</p><p>In another tire according to the invention, also for intercepting crack growth from the outside of the tire, a low modulus middle rubber layer (7) composed of rubber having a modulus lower than that of the adjoining rubber is arranged in the tire at at least a part of the region extending between the bead portions.</p><p>The growth of cut damage, especially to the side portions of a tire, is prevented by the fault surface or the low modulus middle rubber layer.</p> |
