As public facilities continue to improve, particularly with the advancement of road construction, many roadways now feature road studs ranging from 12 to 10 cm in height. These studs enhance safety, yet some sewage truck drivers ignore them and their height, continuing to drive over them as usual. Although it may seem that the sewage truck or wash truck tires are unaffected on the surface, in reality, there is significant damage to the tires. This damage is not immediately visible, but it poses a隐患 for tire blowouts.

Shandong Feibo Environmental Protection Equipment Co., Ltd. is a professional manufacturer and supplier of various environmental sanitation vehicles and accessories, including water sprayers, multi-functional dust suppression vehicles, sludge suction trucks, waste suction trucks, cleaning and suction trucks, wastewater treatment vehicles, bulk feed transport trucks, compactor garbage trucks, sweeping vehicles, and water tank fire trucks. The company currently owns over 100 large-scale production units and more than 10 sets of testing equipment.

As public facilities are being improved, particularly with the advancement of road construction, many roads now feature road studs ranging from 12 to 10 cm in height. These studs enhance safety, but some waste suction truck drivers ignore them and continue to drive over them as usual. Although it may seem that the waste suction trucks/flushing waste suction trucks are unaffected on the surface, in reality, they sustain significant tire damage. This is not immediately apparent, but it poses a hidden risk of tire blowouts.

The tires of vacuum cleaner trucks are constructed with cord yarns. Cleaning the tires of vacuum cleaner trucks is not like cleaning tank tracks; when the tires roll over manhole covers, they usually break a few cord yarns. Too many times can lead to the early retirement of the tires, thereby shortening their lifespan. Now, let's analyze tires with a 60 flat ratio (also known as aspect ratio: the percentage of the height from the rim to the tread face to the tire's cross-sectional width) on vacuum cleaner trucks. If the manhole cover is 15 centimeters high, and the angle between the side of the vacuum cleaner truck tire and the manhole cover is less than 45 degrees, and the vehicle speed is above 30 km/h, then at least 3 to 4 cord yarns in the vacuum cleaner truck tire will break upon crossing the manhole cover. These data have been experimentally obtained by the National Rubber Tire Quality Testing Center.

For users of washing and suction trucks who are unaware of how to identify the tire height ratio, the editor would like to普及 some knowledge on this subject. The tire aspect ratio is typically visible on the side of the tire. A tire aspect ratio below 45 is considered thin. The cord is the skeletal material of the tire, primarily used in rubber products such as washing and suction truck tires, conveyor belts, and drive belts.
