What factors will cause tire imbalance during tire production?

The imbalance of the tire means that the center of gravity of the tire is not in the same plane as the axis of rotation, so there will be vibration, noise and other problems when driving at high speed.

1. Tread imbalance
The imbalance of tire tread means that the tread of a tire is thicker in one position and thinner in another. This imbalance is usually caused by defects of tire curtain and uneven distribution of rubber materials.
2. Bead imbalance
Bead imbalance refers to the uneven surface between the wheel hub and the tire. The imbalance of the wheel hub surface may be caused by defects or wear in the manufacturing process, while the imbalance of the tire may be caused by defects in the interface of the tire bead or improper installation.

3. Unbalanced steel cord
The steel cord is an important part of the tire skeleton. If the distribution of the steel cord is uneven, it will also lead to the imbalance of the tire.
4. Unbalanced adhesive layer
The rubber layer of the tire may also cause the imbalance of the tire. Unbalance of the adhesive layer is usually caused by uneven distribution of the adhesive layer or errors in the manufacturing process.

5. Production error
In the production process, various errors will also lead to tire imbalance. For example, the thickness of the tread is not accurately measured, and the bead is not fully aligned with the wheel hub when installing the bead.
To sum up, the imbalance of automobile tires is caused by a combination of multiple factors. In order to reduce the imbalance of tires, the manufacturer needs to take effective measures to control the impact of various factors, and strictly comply with the production process standards and quality control standards to ensure that the quality and performance of tires meet the requirements. For users, timely balancing of tires can also effectively reduce the impact of tire imbalance.
The automatic tire dynamic balance machine developed by Hangzhou Jizhi is applied to the automatic dynamic balance detection system of the semi-steel radial tire of the automobile, and is applicable to the online detection of the static and dynamic imbalance of the semi-steel radial tire. It can carry out automatic identification of tire bar code, interact with MES data, obtain tire type information, have automatic lubrication function, and can automatically mark and grade tires according to test results.
