The invention discloses a vehicle tyre management method and a device for the internet of vehicles. The method comprises the steps of reading an RFID tag inside a tyre by an RFID read-write device to acquire the ID information of the tyre; based on the ID information of the tyre, searching the data parameters of the tyre in a database, wherein the data parameters are composed of at least one of the following parameters: the basic data of the tyre, the quality condition of the tyre, the pressure of the tyre, the usage time, the driving mileage and the retread number of times; processing the data parameters of the tyre to generate the suggestion information, wherein the suggestion information is composed of at least one of the following parameters: the retread time of the tyre, the maximum retread number of times of the tyre, the suitable road surface of the tyre, the service life of the tyre, and the maximum safety driving mileage of the tyre; and sending the at least one suggestion information to user equipment. According to the technical scheme of the invention, the problem in the prior art that since a tyre cannot be effectively monitored, the tyre is excessively utilized to be shortened in service life can be solved. Meanwhile, the problems in the prior art that the resource is wasted due to the unreasonable replacement of the tyre and the occurrence of traffic accidents due to the non-timely replacement of the tyre are also solved.

A measurement system scans the given surface of a tire component (e.g., a brush-finished tread or buffed tire casing) to electronically measure data points corresponding to vertical and horizontal coordinates along the given surface. Associated computer processors electronically calculate the slope at a plurality of different locations by determining the degree of steepness (e.g., rise over run, angle or grade) between selected ones of the first and second coordinates and electronically comparing at least one slope-based parameter to one or more predetermined levels to determine a characterization defining one or more of surface adhesion fitness, finishing brush wear level and brush bristle placement location. Slope may be determined between every adjacent pair of data points or between selected data points (e.g., identified local maximum and minimum). The at least one-slope based parameter compared to the predetermined levels may correspond to the slopes themselves or to a calculated average slope value.

A retreaded pneumatic truck tire includes a used carcass having a uniform annular attachment area and a retread element. The retread element secures to the attachment area of the used carcass. The retread element has a tread pattern comprising a first circumferential groove separating the tread pattern into a first shoulder rib and an intermediate rib and a second circumferential groove separating the tread pattern into the intermediate rib and a second shoulder rib. The tread pattern further comprises a first plurality of identical arcuate notches extending axially and circumferentially across the first circumferential groove and a second plurality of identical arcuate notches extending axially and circumferentially across the second circumferential groove. The first plurality of arcuate notches are offset circumferentially from the second plurality of arcuate notches.

The invention relates to the repair of a tire, in particular to a method for retreading and preparing the broken retread of the steel cord layer of a radial ply tire, which is characterized in that: recombination is carried out to carcass compound 4 is brushed on the polished coarse and cottony pitting surface of the tire body 1 in the first step; heads and ends of an Alpha angle and Alpha 1 of the first steel cord layer 2 are connected with each other to complete a bonding of the steel cord layer 2; the steel cord layer 2 is pressed layer by layer; each two steel cord layers 2 are bonded with each other by middle glue 3. The method has the advantages of simple operation, low cost, waste utilization and energy saving, can raise the utilization rate of the used tire by from 10 percent to above 20 percent, raise the service life of the retread from original 70 percent of the new tire to above 90 percent and save the energy consumption by 30 percent and the utilized materials are only 20 to 30 percent of the new tire. The cost is not increased on the basis of the original retread. The price for using the retread can be saved by above 50 percent compared with the price of the new tire.

This invention provides a tread for retread tire capable of lowering a running temperature to suppress deterioration of peel strength at a retreading face between a tread and a base tire and further obtaining a good peel strength without sacrificing a tear resistance. In a tread 1 for retread tire comprising a cap rubber 2 located side a front surface of the tread and a base rubber 3 located side a bottom surface of the tread, a loss tangent (tan δ) of the base rubber 3 at 25° C. and 2% strain is not more than 0.10 and an elongation at break (Eb) of the base rubber 3 is not less than 460%. Also, this invention provides a retread tire comprising such a tread for retread tire.

Existing processes and equipment for curing tire assemblies can be modified, using the teaching disclosed herein, to implement and achieve the benefits of the present invention.

The invention discloses a process for repairing and coating an automobile rim, relating to the technical field of automobile beautifying and caring. An operation flow comprises the following steps of: checking the situation of the rim; detaching the rim; checking the damage situation of the rim; checking the polishing situation; sealing edges; spraying priming paint and colored paint; spraying rim coating liquid; pouring the rim coating liquid back to the original position of the rim coating liquid is not used up, sealing and storing at a dark and shady place for later use; checking the rim; and installing. By adopting the process, gaps, scratches, retreads and the like on the rim can be repaired, the original glossiness of the rim can be quickly and effectively recovered after repairing and coating, and the original automobile hardness is enhanced. A rim repairing stick has high adhesion, and is made of the same material as an aluminum ring; a surface rim coating agent is protected; and no difference exists between a repaired rim and a new rim.
