Methods of improving properties of the aramid cord/tire rubber system and the research for it in home-abroad are reviewed in details,especially in China,America,Japan,Germany and some countries in Europe the study is perfectly carried out.

A loaddeformation testing system is established for executing the uniaxialtension testing of the tire rubber in a larger deformation range.

The trends of tire technology,tire performances, requirements of tire rubbers,and recent developments of tire synthetic rubbers were analyzed.

On the basis of UG, the five-axis processing method of moulding copper electrode for rubber tyre floral texture of electrical bicycle is stated.

By using catalyst A, the catalytic splitting decomposition of waste rubber tyre was developed.

Aiming at the existing problem of storing and taking rubber tyre in the full-automatic storehouse,lower using rate of storehouse and tyre deformation because of the difficulty in adjusting the tyre orientation,the paper introduces a new automatic three-dimension rubber tyre storehouse,concept is artful,design is reasonable and structure is simple.

The experiments on the friction properties of tire tread rubber are carried out on a self-developed friction test rig for revealing how the friction coefficient varies with the pressure and sliding velocity.

The authers of this disquisition mostly discussed the rolling frictions between the rubber tire and hard road surface by applying the knowledge as geostatics,tribology,rolling dynam,then made some conclusions about the action process and experiential formula of rolling friction.
