In a pneumatic tire T including an adhesive sealant layer 5 disposed inward of an inner liner 4 in a region corresponding to its tread portion 1, the adhesive sealant layer 5 is formed of a laminate including: an auxiliary rubber layer 5a disposed closer to the inner liner 4, the compression set of the auxiliary rubber layer 5a being set at 40% or less; and an adhesive sealant material 5b disposed inward of the auxiliary rubber layer 5a.
Claims4
A pneumatic tire including an adhesive sealant layer disposed inward of an inner liner in a region corresponding to a tread portion, wherein the adhesive sealant layer is set at 3 mm to 6 mm, and is formed of a laminate including:
- an auxiliary rubber layer disposed closer to the inner liner and occupying 20% to 60% of the thickness of the adhesive sealant layer, the compression set of the auxiliary rubber layer being 40% or less;
- and
- an adhesive sealant material disposed inward of the auxiliary rubber layer;
- wherein the inner liner is formed in a way that the thickness of the inner liner is thicker in its area with which the adhesive sealant layer is in contact than in its other area.
