| 摘要 |
This invention relates to a light duty tire (e.g. passenger tire or light duty truck tire) designed for a load bearing capacity of a maximum of 3,500 pounds (1587 kg) with a tread of a cap/base construction with at least one underlying silica-rich, cis 1,4-polyisoprene rubber based intermediate transition rubber layer to promote a reduced internal heat generation for the light duty tire and to therefore promote a light load carrying light duty tire which is more durable for the long haul. Such light duty tire tread is intended for use with light loads in which internal heat may be generated within the tire, including the tire tread, during use.
