摘要： PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of enhancing lateral stiffness without impairing a grounding property, and improving steering stability.
SOLUTION: Between right and left bead portions 3, two-layered carcass layers 4, 5 having reinforcing cords (a) aligned so as to tilt at an angle θ of 60 to 86° in regard to the tire circumferential direction TC are extended. The two-layered carcass layers 4, 5 are disposed so as to make the reinforcing cords (a) intersect with one another while reversing tilting directions to the tire circumferential direction TC. A reinforcing layer 12 wherein a reinforcing cord (f) extending along the tire circumferential direction TC aligned in a tire diametrical direction and buried in a rubber layer (r), is provided on an inner surface 2a of a side wall portion 2. The width (w) of the reinforcing layer 12 is within a range of 25 to 100% of tire cross sectional height TH.

摘要： PROBLEM TO BE SOLVED: To provide a pneumatic tire improved in durability while maintaining driving stability, even in the case of forming three carcass layers.
SOLUTION: The pneumatic tire has three carcass layers 4A-4C comprising several carcass cords inclined with respect to the tire radial direction and arranged to cross each other between the carcass layers. When the number of twists T (times/10cm) of the carcass cord included in first or the third carcass layer 4A-4C counted from the inner peripheral side of the tire and a twist coefficient (T×√D) obtained from a total display decitex D (dtex) is K1 or K3, K1 and K3 satisfy a relation that K2/K1≥1.1, and K2/K3≥1.1, and K2≤3200.

摘要： PROBLEM TO BE SOLVED: To suppress tilting of a bead portion of a tire and stably keep tire running performance by providing a carcass ply with a plurality of reinforcing members arranged in a width direction of a tire tread and crossing ply cords. SOLUTION: At least one carcass ply consisting of steel cords and the like is provided with ply cords 4a which are arranged around a tire in a width direction of a tread to form a basic frame of the carcass ply, and a plurality of reinforcing members 4b which are arranged in the width direction of the tread and crossing the ply cords 4a (which is in a direction of tire rotation). In case of a pneumatic tire for a heavy-duty vehicle which is to be applied with particularly heavy load, when excessive load is applied to the tire, spacing between the ply cords 4a widens and thus a bead portion of the tire is tilted. However, the reinforcing members 4b can surely suppress these gaps between the ply cords 4a.

摘要： PURPOSE:To improve reduction of weight, uniformity and durability of the captioned tire by using, a ply made of knitted cloth in which parallel warps are formed by a knitting yarn of thin fibre, as a reinforcing material in a pneumatic tire in which knitted cloth carcass is used. CONSTITUTION:Parallelly arranged warps 3 are formed in a knitted cloth 1 with fine knitting yarns 5 and 6 such as nylon 6 of 5-50 denier and which are adhesive to rubber. After adhesion treatment and heat treatment are applied to this knitted cloth 1, topping rubber treatment is applied, and it is buried in the rubber, and thus it is made as a reinforcing material. Therefore, reduction of weight, uniformity and durability can be improved.

摘要： PURPOSE:To improve an endurance capacity for a tire by bringing a weight ratio of an organic vulcanizing accelerator and sulfur in components to a required extent and by producing tread and carcass from products with a weight ratio of a metallic oxide and a fatty acids within a required extent. CONSTITUTION:A weight ratio of an organic vulcanizing accelerator containing a vulcanizing accelerator of sulphenic amide family being added to a rubber component produced by adding compounds of one or two kinds of rubber of diene-family to a natural rubber as a main body, and sulfur is brought to an extent exceeding 1.0 and below 2.4. And a product is made and used, having a weight ratio of a metallic oxide or a metallic salt and a fetty acid resting within an extent of 1.5-2.5 for tread and 2.0-5.0 for carcass. With these compositions, chipping resistant capacity, cutting resistant capacity, tiering resistant capacity, resistivity against heat generation and others are increased, so that an endurance characteristic is improved.
