How to do a good job in tire anti compression protection for whole vehicle export packing

During the process of exporting heavy-duty trucks and trailers by sea, tires are one of the most prone components to hidden damage. The interior space of the container is narrow and the fixed points are limited. During transportation, the vehicle may experience conditions such as wave turbulence, ship shaking, and ship tilting, which can easily cause problems such as one-sided compression, biased deformation, tire wall indentation, and bulging of the tires. Many vehicles experience tire scrap, appearance defects, and three guarantee refusal to compensate after unloading at the port, which affects the delivery quality. Standardizing the packaging and protection process for the entire vehicle and ensuring proper tire compression protection are key details in the delivery of exported vehicles.
Reasonably control the standard tire pressure to avoid overfilling or insufficient air when packing. Many packing personnel have a misconception that the higher the tire pressure, the safer it is. However, under high pressure, the tire rigidity is too strong, and bumps and compressions can easily cause damage to the tire wall; If the tire pressure is too low, the tread will collapse and the area under stress will be too large, which is prone to permanent indentation. The export packaging of the whole vehicle needs to be inflated according to the factory's standard air pressure to maintain a balance between tire support and flexibility, effectively resisting the continuous compression stress of sea transportation.
Standardize the placement posture of vehicles and eliminate unilateral suspension and unbalanced loading. When loading containers, the vehicle may tilt, the wheels may be pressed against the line, and one side of the tire may be suspended, which can lead to long-term overloading and pressure on a single wheel. Prolonged sea transportation can directly cause delamination and deformation of the tire wall. Packing must ensure that all four wheels are completely on the ground, the body is aligned, and the force is evenly distributed. It is forbidden to place them diagonally or misplaced. Simultaneously control the center of gravity of the entire vehicle to avoid unilateral tire compression and overload caused by the front or rear of the vehicle being too heavy.
Install specialized anti slip pads and limit blocks. Relying solely on handbrake and body fixation cannot offset the sea freight shaking displacement. The formal export process requires the installation of anti slip rubber pads or wooden blocks on both sides of the front and rear wheels to block the gap between the wheels and prevent the vehicle from moving forward and backward or shifting left and right. By using limit fixation, the tire can be prevented from repeatedly rubbing and squeezing the casing at the root, greatly reducing the risk of tire surface wear and deformation caused by squeezing.
The binding force is symmetrical to avoid the body from pulling or shifting. Asymmetric binding points and uneven tension of the entire vehicle can forcibly pull and deflect the body, causing lateral compression between the tires and the ground, resulting in hidden damage to the tire walls. Packing and bundling should follow the principles of left-right symmetry and front to back balance, with uniform tightening force to ensure the stability of the vehicle body and reduce lateral stress and local compression on the tires.
Take long-term sea transportation static protection measures. Long distance sea transportation has a long cycle, and tires are prone to flat marks due to long-term stress on a single point. For ultra long sea freight orders, the support points can be adjusted appropriately within the allowable packing range to ensure even tire stress. At the same time, clean the impurities on the tread to avoid local damage caused by hard particle pads pressing the tread.
In summary, the compression damage to the exported tires of the whole vehicle is mostly caused by non-standard packing details. Standardized tire pressure, proper vehicle posture, installation of limit pads, symmetrical binding and fixation, a complete set of simple protection processes can effectively avoid tire deformation, indentation, and bulging problems, ensuring the appearance and condition of overseas arriving vehicles meet standards, and improving the quality of exported vehicle delivery and customer satisfaction.
