Recently, information from the State Intellectual Property Office shows that Zhongce Rubber Group Co., Ltd. and Hangzhou Haichao Rubber Co., Ltd. jointly applied for a patent titled “A high-handling performance radial tire for new energy vehicles and a manufacturing method.”
The application publication number is CN122008739A, the application date is April 1, 2026, and the publication date is May 12, 2026.
This patent involves the field of tire manufacturing technology, and its core highlight lies in the placement of aramid U-shaped wrapping cloth at the bead.
This U-shaped wrapping cloth is wrapped around the apex and forms a U-shaped structure, covering the entire internal and external surfaces of the apex.
The thickness of the U-shaped wrapping cloth is 1.0 – 1.4mm, and the cord angle α is 40 – 50°; its inner endpoint is at least 10mm higher than the top of the apex in the radial direction, and its outer endpoint is at least 10mm lower than the top of the apex in the radial direction.
During the manufacturing process, it is necessary to position and fit the U-shaped wrapping cloth to form the bead compound at the same fitting station, and then assemble it with the carcass and vulcanize it to shape.
This solution can optimize the bead-sidewall rigidity transition and stress distribution, improve torsional stiffness and dry and wet handling/braking performance, reduce the risk of end-point superimposed rubber shortage and separation, and is also conducive to mass production consistency and low rolling resistance design.
Zhongce Rubber was established in 1992 and is a leading enterprise in the domestic tire industry.
It focuses on the manufacturing of tires and rubber products, has advantages in the entire industry chain, and has outstanding investment value.
Its main business is the processing and manufacturing of tires and rubber products. The Shenwan industry it belongs to is automobiles – auto parts – tires and wheels. The concept segment covers low price-earning ratios, tires, and two-wheeled vehicles.
In terms of operating performance, Zhongce Rubber performed well in 2025.
Operating income reached 44.956 billion yuan, ranking first among 22 peers, far exceeding the industry average of 10.395 billion yuan and the median of 5.119 billion yuan.
Among its main businesses, tires accounted for 87.24%, reaching 39.22 billion yuan.
In terms of net profit, Zhongce Rubber will be 4.147 billion yuan in 2025, also ranking first among the 22 peers. The industry average is 701 million yuan and the median is 294 million yuan.
Zhongce Rubber Group Co., Ltd. has recently applied for multiple patents.
For example, “an electric vehicle tire tread wear simulation method, system, readable media and program product”, “a groove-bottom crack-proof low-noise new energy vehicle tire and its optimized design method and system”, etc.
These patents cover multiple aspects of tire manufacturing and reflect Zhongce Rubber’s continuous investment and innovation capabilities in technology research and development.
Hangzhou Haichao Rubber Co., Ltd. was established in 2014 and is a large-scale enterprise.
The company is also actively exploring tire technology research and development. The new energy tire patent jointly applied for with Zhongce Rubber, as well as its own multiple patent applications, all show its technical strength and development potential in the industry.
With the continuous development of the new energy vehicle market, the performance requirements for tires are also getting higher and higher.
This patent application by Zhongce Rubber and Hangzhou Haichao Rubber Co., Ltd. is expected to provide better quality tire products for new energy vehicles, meet market demand, and promote technological progress in the tire industry.
