Key Points For Daily Inspection Of Heavy Truck Tires To Avoid The Risk Of Long-distance Tire Blowouts

Tires are the core safety components for long-distance transportation of heavy trucks. Due to complex road conditions such as cross-border trunk lines and long-distance travel across provinces, continuous high-speed driving, gravel on the road surface, and large temperature differences, they are prone to tire damage, bulges, and blowouts. Sudden tire blowouts during long-distance driving can not only cause vehicle loss of control and traffic safety accidents, but also lead to cargo delays, vehicle delays, and high downtime losses. Most tire failures are not sudden, but rather caused by inadequate daily inspections and accumulation of hidden dangers. Mastering the key points of standardized daily inspections of heavy-duty truck tires and identifying hidden dangers in advance is the key to ensuring safe attendance and reducing costs and increasing efficiency for long-distance vehicle fleets.
Accurately check tire pressure to eliminate high and low pressure hazards. Abnormal tire pressure is the primary cause of long-distance tire blowouts. Low tire pressure can cause excessive bending and friction heating of the tire body, resulting in fatigue fracture of the internal curtain; If the tire pressure is too high, the center of the tire surface will wear more severely, the impact resistance will decrease, and crushing gravel pits is prone to explosion. Daily inspections must adhere to cold vehicle pressure measurement, strictly adjust according to the original factory standard values of the vehicle, and avoid making judgments based on hand feel. Before long-distance travel, the tire pressure should be calibrated uniformly, and slight adjustments can be made in high-temperature environments. At the same time, the tire pressure monitoring status should be checked to prevent abnormal tire pressure from causing problems when driving on the road.
Comprehensively investigate the hidden dangers of tread and sidewall damage. Long distance road surfaces are filled with gravel, metal debris, and miscellaneous objects, which are easily embedded in the tread patterns, causing slow air release and local damage. Before driving every day, it is necessary to clean the tire seams, stones, and debris one by one, and carefully inspect the tire surface for cracks, falling pieces, and uneven wear. Pay close attention to the position of the tire sidewall. The tire sidewall cords are weak, and long-term bumps and scratches can easily cause bulges, scratches, and skin damage. Once the tire sidewall bulges or cords are found to be exposed, they must be replaced immediately to resolutely prevent long-distance driving with diseases.
Check the tire wear status and control the replacement node. Long term heavy load long-distance driving can cause normal tire wear. If unilateral wear, serrated wear, or local eccentric wear occurs, it is mostly caused by unstable tire pressure and abnormal chassis positioning. The steering tire has the greatest impact on driving safety, with stricter wear standards and shallow patterns that need to be replaced in a timely manner. At the same time, ensure that the coaxial tire pattern and wear degree are consistent, avoid uneven grip causing driving deviation and tire slippage, and reduce safety risks during high-speed driving.
Check the wheel hub, air nozzle, and fastening status. Many tire blowouts are caused by loose and aging parts. During inspection, it is necessary to check whether the valve is aging, cracked, leaking, and whether the valve cap is complete to prevent sand and dust from entering and causing slow leakage. At the same time, check whether the wheel hub is deformed, cracked, or corroded, and tighten the tire screws one by one to prevent loose screws and tire displacement during high-speed driving. In addition, it is necessary to investigate brake and drag brake faults. The high temperature of the drag brake will continue to scorch the tires, accelerate rubber aging, and induce heat induced tire blowouts.
The safety of long-distance transportation tires focuses on prevention, standardizing daily inspection procedures, implementing four core tasks: tire pressure calibration, damage investigation, wear monitoring, and accessory inspection, which can avoid the vast majority of tire blowout risks. The overseas long-distance road conditions are complex and difficult to maintain. The fleet needs to develop the habit of daily pre inspection and regular inspection, timely deal with hidden tire hazards, effectively reduce the probability of failure, ensure the safety and stability of long-distance transportation, and reduce maintenance and downtime losses.
