1.Drill a hole
Has your SHACMAN dump truck had a punctured tire? If so, how long ago did it happen? In fact, for tires that have been patched for a long time, even if they are used temporarily, there will be no problem at all. The bearing capacity under load will not be as good as before: In addition, if the same dump truck tire has more than 3 holes, we still recommend that you replace it as soon as possible.
2.Bulge
If a SHACMAN dump truck drives over potholes, obstacles and curbs at high speed, parts of the tire will be severely deformed under the huge impact force, and the internal pressure will increase instantly. The direct consequence of this is the sidewall curtain. The wire breaks violently and causes bulging. In addition, under the same impact force, tires with a low aspect ratio are more likely to cause sidewall bulges than tires with a high aspect ratio. Tires that have bulged must be replaced immediately, otherwise there is a risk of tire blowout.
3.Pattern
Generally speaking, the tires of SHACMAN dump trucks in normal use can be replaced every 60,000 kilometers or two years, but tires with serious tread wear should be replaced earlier. Nowadays, quick repair shops have pattern wear scales, and car owners can buy one to check the pattern wear of their tires at any time. In addition, the increase in tread cracks is also a symbol of serious aging. You can usually spray some tire protective wax appropriately, and try not to touch corrosive liquids when driving.
4.Air pressure
Most of the SHACMAN dump trucks now use tubeless radial tires. For front-wheel drive vehicles, because important driving components such as the engine and gearbox are located in the front, the front wheels sometimes look a bit flat, but Visual inspection is inaccurate and must be measured with a special tire pressure gauge. Generally speaking, the air pressure of the front wheel is between 2.0 Pa and 2.2 Pa. (Since the purpose and design of each vehicle are different, it is best to refer to the factory value calibrated in the instruction manual). It can be appropriately lower in summer.
5.Pebbles
Some SHACMAN dump trucks often hear their dump trucks making a “pop” sound while driving, but there is no problem when using the truck. At this time, you need to check whether there are any small stones stuck in the tires. In the pattern. In fact, as long as you take the time to use a key to dig out these small stones in the tread pattern, it will not only make the tire’s braking grip more stable, but also avoid tire noise.
6. Spare tire
If you want the spare tire to play a real emergency role, you must pay attention to its maintenance. First of all, the air pressure of the spare tire of the SHACMAN dump truck should be checked frequently; secondly, the spare tire should pay attention to preventing oil corrosion. The spare tire is a rubber product and is most afraid of corrosion by various oil products. When a tire is stained with oil, it will soon bulge and corrode, which will greatly reduce the service life of the spare tir
