The overall visual effect of the logo is that it is round but not round. A slash appears upward in the upper right corner, which means "promotion" and indicates that "Zhengxin" will be the company. By continuously forging ahead, production and operation will flourish and the trend of development will remain unchanged. In addition, Chengshin tires all have the words "Chengshin Tire" on a yellow background. They also have an English logo "Chengshin Tire" and the abbreviation "CST" with several English letters. The side logo is as follows:
Zhengxin tires are long-lasting and durable, have guaranteed safety, are easier to install and have better airtightness. At the same time, the maneuverability is also very good, and the price is at a medium level. Zhengxin vehicle tires can be divided into four product series, namely comfort and silent mode series, sports control series, balance series, and winter wind and snow series.
Zhengxin tires are tires produced by Zhengxin Vulcanized Rubber Industrial Production Co., Ltd. The company was founded in Taiwan on January 1, 1967.

What is the best car tire pressure? Car tire pressure is generally between 2.3-2.5. , which is also a very commonly used normal range of tire pressure. However, it is still necessary to make adjustments based on the pressure value recommended by the manufacturer according to the situation, because the standard tire pressure mainly takes into account factors such as the weight of the car body and the height of the chassis when initially setting. Therefore, the standard tire pressures of different cars are different.
The manufacturer recommends normal tire pressure as indicated in the vehicle manual, the logo on the cab door (around the B-pillar), the drawer next to the driver's seat, and the oil cap side door. It will occur in a variety of ways, some in bar, some in psi, and some in kg/cm2 and kpa. The conversion between them is 14.5psi=1.02kg/cm2=1bar=100kpa . The resulting list of car tire pressure standards is as follows:
barpsikg/cm2kpa2.333.62.342302.434.82.452402.536.32.552502.637.72.65260
In fact, the standard tire pressure is only As a reference, tire pressure is also affected by various factors:
Carrying load
1. Full or half load: according to the lower limit of the tire pressure standard.
2. Fully loaded: limited by tire pressure standard value.
Tire conditions
1. New tires: The air pressure is increased by about 0.2bar according to the tire standard.
2. Used tires: Reduce the tire pressure appropriately according to the tire pressure standard. If the damage is obvious, follow the lower limit of the tire pressure standard.
3. Soft tires: Increase the tire pressure by about 0.2 bar appropriately according to the standard tire pressure.
4. Hard tires: follow the lower limit of standard tire pressure.
Real-time driving conditions
1. Shaking ground: Moderately reduce the tire pressure by 0.2 bar according to the standard air pressure of car tires.
2. Running fast and long distances: Increase the tire pressure by 0.2 bar appropriately according to the lower limit of the car tire standard.
Seasonal factors
1. Winter: Increase the tire pressure by about 0.1-0.2bar according to the standard value of the tire.
2. Summer: According to the lower limit of the standard air pressure of automobile tire pressure standards.
The environment for accurate tire pressure measurement
The tire pressure values ??of hot tires and cold tires are different, and the difference between the two is about 0.3bar. Generally, the standard tire pressure recommended by manufacturers refers to cold tires.
Special attention should be paid to the fact that the pressure of the spare tire should be higher, generally higher than 250kpa, to prevent the standard air pressure from being too low, and then adjust it to the appropriate tire pressure during use.
