(57) [Summary] [Problem] Off-road chip-resistant pneumatic tire (1) 0). The tire includes an organic reinforcement overlay (22, 22b) embedded in or below a tread (18) and / or a sidewall (20), and is used for off-road such as mining. Low sulfur rubber (17) is used to coat the organic reinforcement (11), which cooperates with the organic reinforcement to form the tread (18) and the rubber for forming the sidewall (20). Match to help prevent chipping and chunking. Organic strands and cords (1 1) has a circular cross-section, at least 2000 denier (2200 dTex), at least 3.5 g / denier (31 cN / Tex) toughness, 20 g / denier (177 cN / Tex) initial strength and 10% fracture It has elongation and at most 10% shrinkage. |
