As temperatures rise with the onset of summer, scorching road surfaces take a toll on truck tires; many blowout accidents stem from a lack of routine inspection and maintenance. Don’t wait for a dangerous situation to arise—follow these four maintenance tips to proactively mitigate driving risks.
1. Conduct a walk-around inspection before and after trips to spot hidden tire damage
Road debris—such as gravel, metal shards, and glass—along with potholes and bumps, can cause subtle tire damage. Cultivating the habit of walking around the vehicle allows you to detect potential issues early:
(1) Check the tread: Look for embedded nails or glass, and inspect the surface for cuts or damage.
(2) Check the sidewall: Bulges or cracks in the sidewall are high-risk warning signs of a blowout; address them immediately.
(3) Check the tread pattern: Observe whether wear is even; uneven wear or tread worn down to the wear indicator line requires maintenance.
(4) Routine habit: Spend one minute walking around the vehicle before and after every trip to prevent minor issues from escalating.
2. Strictly maintain standard tire pressure to avoid the dangers of over- or under-inflation
In summer, asphalt road surface temperatures can exceed 70°C. Tire pressure fluctuates easily in high-heat environments, and both extremes pose hidden dangers:
(1) Excessive tire pressure
The tire stiffens, and the contact patch shrinks, reducing grip and increasing braking distance. Driving in sustained high heat causes internal pressure to rise continuously, exponentially increasing the risk of a blowout.
(2) Insufficient tire pressure
The sidewall undergoes repeated deformation, accelerating tire wear and increasing rolling resistance. This leads to higher fuel consumption and drives up operating costs.
Correct approach
Regularly measure pressure using a professional gauge and strictly adhere to the manufacturer’s recommended standards; do not rely on visual estimation or touch. 3. Minimize emergency braking to reduce strain on tires and brakes
Frequent, hard braking damages more than just the brake pads; it also accelerates tire aging and wear:
Sudden braking causes brake drums to heat up rapidly; this heat transfers to the tire rubber, accelerating the aging and hardening process;
Frequent braking on mountainous roads or long downhill stretches causes tires to wear out much faster than on flat terrain;
Safe driving tips: Anticipate road conditions in advance, control speed using the throttle, and utilize engine braking to assist in slowing down on long descents—this relieves the burden on both tires and brakes.
4. Avoid dousing hot tires with cold water; natural cooling is the safe approach
Many drivers splash cold water on scorching tires after a long trip to cool them down, but this practice is extremely dangerous:
The drastic temperature difference causes the outer rubber to contract rapidly while internal heat remains trapped, leading to rubber delamination and aging;
Sudden cooling can deform the wheel hub, causing an imbalance in stress distribution and creating a risk of sudden tire blowout;
Thermal shock to the brake drums poses a risk of cracking or shattering, potentially leading to serious accidents.
Proper cooling method
Park the vehicle in a cool, well-ventilated area and let it sit, allowing the heat to dissipate slowly through natural ventilation.
5. Maintenance Summary
Tires are particularly vulnerable to the effects of prolonged exposure to scorching heat. Diligent daily inspection and maintenance can prevent blowouts; proper tire care ensures that every freight journey is safe and secure.
