Abstract
A chip resistant pneumatic tire ( ) is provided. The tire has an original reinforced rubber sheet ( ) embedded in or under its tread ( ) and/or sidewall ( ), and is used in off the road applications such as mining. Low sulfur rubber ( ) is used to coat the organic reinforcement ( ), and its shown that such rubber ( ) is more compatible with rubber used to form the tread ( ) or sidewall ( ), which together with the organic reinforcement ( ), helps prevent chipping and chunking in the tread ( ) and sidewall ( ). The illustrated organic filaments of cords ( ) have a round cross section and are at least 2000 denier (2200 dTex) and have a tenacity of at least 3.5 g/denier (31 cN/Tex), an initial modulus of at least 20 g/denier (177 cN/Tex), an elongation at break of at least 10%, and a shrinkage of at most 10%.
