  Under normal circumstances, heavy truck tires with normal wear simply roll in driving, and the ground resistance of tires is mainly the rolling friction. The rapid tire wear-out is mainly due to the sliding friction between the whole tread, a pattern, or a point with the ground.   Judging the direction of friction at each point is the key to accurately judge the driving state of heavy truck tires, which has also become a faster and better way to solve problems in practical technology in addition to equipment detection.   Here we summarize several phenomena and the causes of the serious wear-out problem of heavy truck tyres for your reference, so that you can suit the remedy to the case whenever the problems occur.   1. Bidirectional wear in the same position   Phenomenon: Heavy truck tyres are worn flat in the same position around the tyres.   Causes: The brake is locked, resulting in that the tyres are dragged and slide on the ground; check the brake mechanical parts fault and brake

  We all know that mining dump truck tires  are divided into tire with inner tube and tubeless tire. Today, I'd like to explain the steps of loading and unloading tires with inner tubes.   1. Manual removal steps for tire with inner tube 1) The tire should be placed flat on the ground with the valve upward to remove the valve cap and valve core, and the inner tube should be completely deflated;   2) Knock the impact bar along the toe to make the toe of tire fall off;   3) Use a special removal tool to clamp the lock ring, and the other end to jam the rim bolt hole;   4) Insert the lock ring removal rod, remove one end of the lock ring, and pry out the lock ring with the lock ring removal rod;   5) Pay attention to the valve during the disassembly process to prevent the valve from being damaged;   6) Find a small steel ring and press the tire onto the small steel ring, so that the rim and tire can be easily separated;   7) Take out the inner tube and cushion belt and place the compo

 With the gradual improvement of people's economic level in modern society, cars are becoming more and more popular in our life. Cars can be used as both a means of transportation and a source of income for some consumers, among which coaches are the most representative ones. However, this kind of vehicle often wear out very quickly and the tires need to be changed frequently, but many car owners feel very troublesome about the replacement of coach tires and do not know how to choose. There are many types, specifications, structures and materials of coach tires. As one of the top bus tire experts, Aulice can tell you how to choose coach tyres .   Methods to choose coach tyres 1. Different kinds of tires with different structures can not be used on the same car. You can't use ordinary tires and anti-skid tires at the same time, either. When selecting tires on the same axle, you must pay attention to the above-mentioned conditions, otherwise, the stability of the car will deterio

1. Choose the right speed level for high-speed running   The tyre speed level is one of the properties of the tire. The speed level marked on the tyre is the highest safe driving speed designed for the tire. Driving below this speed, tire performance and life will be the best. The common crane tyres for sale    speed levels are J (100km/h), K (110km/h), L (110km/h), and M (110km/h).   2. The choice of mining dump truck tires  on different roads should also be different   1. Mine road: The mine road is complex, muddy, slippery, which has many rocks on the road. It is a strict test for truck tires. For such road conditions, you'd better choose special tires for engineering vehicles. The large patterns of van tyres for sale can effectively avoid the damage to the tyres and also offer the good tire grip to ensure the normal running of the van.   2. Pavement road: The pavement road is the road we usually say. Tubeless tires are the main choice. Its tubeless design allows low tire temper

  T he H istory of T yre 1. Early tires: Tires were made of wood, iron and other materials a long time ago. The first hollow wheel was invented by Robert Thomson, an Englishman, in 1845. He proposed filling the elastic bag with compressed air to ease the vibration and impact during movement. Although at that time tires were made of leather and canvas coated with rubber, the hollow wheel had already shown the advantage of low rolling resistance.   2. Pneumatic tires: According to this principle, John Dunlop made hollow rubber tire in 1888, and then Thomas made hollow rubber tire with valve switch. Unfortunately, because there was no canvas in the inner layer, it could not maintain a certain section shape and width.   3. Automobile tires: In 1895, with the appearance of the automobile, inflatable tires have been widely developed. The first sample of automobile tires was appeared in France in 1895, and it is made of plain canvas single-tube tires, but there is tread compound with no patte

  So Much is Hidden in the Numbers on Truck Tyres   Carefully observing the obvious position on the sidewall of heavy duty tyres , you would find a line of number + letter symbols similar to mathematical functions, such as 12.00 R20, 11.00 R20, 295/80 R22.5. And these numbers represent the basic information of the tyre. Take 12.00 R20 as an example, where 12.00 represents inch in British system, and 12 inch refers to tyre tread width. The larger the number, the wider the tire tread, hence the larger the grounding area, and the tire's grip will be improved to a certain extent.   The last two digits of 20 corresponds to the wheel hub, which is often called the diameter of the rim, in inches. Generally speaking, the larger the diameter of the hub, the greater its bearing strength. Many drivers who pull heavy loads tend to have larger diameter wheels with a certain thickness.   The letter R represents the type of tire. Most of the tires in the past did not have this letter. In the past

 Truck Tire Inner Tubes for Sale It's a common knowledge that tires of trucks can be classified as using an inner tube and tubeless, today I will introduce how to skid loader tires for sale for a tire with an inner tube. 1. Steps for removing a tire using a tube manually 1) Put the tire on the ground horizontally, keeping its valve upward. Then, remove the valve cup and the valve core, and blow the tube off completely; 2) Use a tube spanner to knock along the edge of bead toe to make it fall off; 3) Use a professional removal tool to clamp the retaining snap ring, and use the other side of the tool to clamp the rim bolt socket. 4) Insert the retaining snap ring removal rod, remove one side of the retaining snap ring and then prise it. 5) Focus on the valve and avoid damaging it during the process; 6) Find a small steel ring and press the tire on the ring hard, which makes it easy to separate rims from tires; 7) Take off the inner tube and cushion belt, and place all parts properly.

  Should You Change Tractor Tire? This Article Tells You How to Distinguish 1. Serious Wear There is a wear limit sign on each tread groove that is about 2mm thick (1.6mm to be exact). The professional tire shop suggests that when the wear thickness of tires reaches twice the wear limit height (i.e. 3.2mm), it should be frequently checked. If conditions permit, it is recommended to replace it. 2. Punctured Tire Wall Many people know that the sidewall injury is very serious, so they think that the tire should be replaced immediately if the sidewall is punctured. In fact, this is not rigorous. A punctured sidewall is indeed more dangerous than the tread injury. However, not all sidewall damage requires the replacement of tires. The sidewall of each tire has a relevant identification and model. If the damaged part is located on the lower side of the sign near the rim of the hub, the tire must be replaced. Because the intensity of the steel wire here is very weak. After repair, it will be
