1. Air pressure is the life of a tire
Tire pressure has a decisive impact on tire wear, fuel consumption, and damage. Therefore, in order to drive safely, it is necessary to maintain standard pressure and regularly check the pressure.
Standard air pressure: 80% to 100% of the maximum pressure indicated on the tire sidewall (or refer to the instructions of the car factory).
Measurement and adjustment of air pressure: The nature of the work determines the road conditions, travel, load, speed, etc. of the vehicle.
Tire load capacity: The load capacity of a tire corresponds to its inflation pressure, and the reasonable tire pressure must be determined based on the vehicle's load situation. Climate and seasonal changes should not be a reason for adjusting tire pressure.
In the early stage of using a new tire, the outer edge size of the tire may change due to heat generated by bending motion, resulting in a decrease in tire pressure. Therefore, the tire pressure should be checked and adjusted after 24 hours of use or driving for 2000-3000km. When driving at high speeds for a long time, the tire pressure should be increased by 10% to 15%.
2. Hazards of insufficient air pressure
Insufficient air pressure can lead to increased deformation of the tire sidewall, increased heat generation, greatly reducing tire life, and causing the following problems and safety hazards
Excessive wear on the shoulder position of the tire
Increase the possibility of tire collision induced bulging (CBU)
The decrease in adhesion between various components of the tire leads to delamination
Severe insufficient air pressure leads to tire sidewall crushing and damage
Excessive tire bounce causes abnormal wear between the bead and wheel rim, resulting in damage to the bead
Rolling resistance increases, fuel consumption increases
3. The hazards of excessive air pressure
Excessive air pressure can lead to a decrease in the contact area between the tire tread and the ground, an increase in tire body rigidity, a decrease in cushioning, and may cause the following problems and safety hazards
Excessive wear at the center of the tread
Increase the risk of tire rupture or even blowout when subjected to external impact
The reduction in grounding area leads to a decrease in maneuverability and is prone to risks such as tail shaking and sliding
Decreased ride comfort
Long term driving with excessive air pressure can easily cause damage to the vehicle chassis
