What Are the Reasons for the Puncture of the Sanitation Garbage Dump Truck?

The lifespan of tires is actually a false proposition because it can vary from 50,000 to 200,000 kilometers. Truck tires are the epitome of hard work and are a symbol of endurance and resilience. For veteran drivers, tires are like the "feet" of the truck; they can tread on mountainous roads full of rocks and sand, roll on hard ice surfaces, and even travel through scorching deserts. However, they are not immune to their own "fatal flaw" - the sidewall. Today, let's learn about the factors that cause garbage dump trucks to have tire blowouts.

High temperatures cause tire pressure and temperature to rise, increasing the risk of tire blowouts in garbage dump trucks

After prolonged use of the brakes, the brake drums will gradually generate high temperatures. Since the valve stems of garbage dump truck tires are located close to the inner middle position of the tire rim, which is close to the brake drum, the high temperature generated by the brake drum can cause the rubber at the bottom of the valve stem to expand and deteriorate, resulting in poor sealing. For trucks that often drive in mountainous and hilly areas and have to use the brakes for a long time, the sealing of the tire valve stems is generally poor, and the risk of tire blowouts is higher.

Damaged garbage truck tires should be used with caution to ensure safety

Damaged garbage dump truck tires refer to tires whose inner tube has been repaired due to punctures by sharp objects or valve leaks. Repaired tires have a sealing capacity and load capacity far inferior to those that have not been repaired.

The repaired part of the inner tube of a repaired tire is generally padded with a rubber pad, which is used to repair punctures in the outer tire and prevent the repaired tire from "bulging" at the puncture point of the outer tire. However, this protruding rubber pad on the outer surface of the inner tube has a wear and tear effect on the repaired part of the inner tube when under a heavy load or when driving on bumpy roads, making tire blowouts more likely.

Cold water cooling is not advisable, as abrupt temperature changes in garbage dump trucks can cause tire blowouts

After long periods of continuous high-speed driving, tires generate heat. If the heat is not dissipated in time, the tire temperature rises, and excessive temperature rise (above 95℃) can cause tire delamination and even tire blowouts.

Damaged garbage dump truck tires should be replaced promptly to prevent friction-induced heat

Since there are many tires on the rear double-axle and semi-trailer models, it is difficult to detect a blown-out tire. After continued driving, a damaged tire will rub against the good tires, generating heat until another tire blows out. After a double tire blowout, the wheel hub will generate a large amount of sparks through friction with the ground, which can ignite the damaged tire.

In daily driving, 80% of tire problems are related to the sidewall. The sidewall, which is scarred and worn out, is not only thinner than the tire tread but also lacks enough steel wire to bond with, making it more fragile. The actual load capacity of garbage dump trucks exceeds the maximum allowable load of the wheels, causing the tire pressure to increase. When the tire pressure exceeds the sealing pressure of the tire valve stem, tire blowouts can occur.
