Truck vacuum tire assembly and disassembly process
A variety of tire dismantling machines can be used for tyre mounting and dismounting. As each operation method is different, please refer to the user manual supplied by the equipment manufacturer you are using. You still need full lubrication of the rim and bead. Most of the tyres when the machine is running will produce a powerful force, if improper operation, may damage the tire bead.
The disassembly and assembly of tyres is very dangerous. It is not only economic loss, but even personal injury. Therefore, we need to pay enough attention to any small operations and be careful enough. Now let's stress the details of the tyre installation.
Directional tire attention: correct installation for best performanceAn arrow with a directional tread design is provided with an arrow at the shoulder edge of the truck tire to indicate the direction of installation when the tire is transposed. For optimum tyre performance, directional tyres must be properly mounted to the rims to ensure that they are mounted on the vehicle in accordance with the requirements of orientation.For example, when a directional drive tire is fitted to the 8 wheel rim, you can use the rim groove as a reference. The four tyres shall be mounted to the left of the operator according to the arrow, and the other four tyres shall be mounted on the right side of the operator according to the arrow. This ensures that when the wheels are mounted to the vehicle, all the tires point to the correct transposition direction.When the wear of the directional tire exceeds 50%, generally, it is installed in the opposite direction of the transposition direction, which has no negative influence on the driving.On the other hand, the direction of tire wear from 50% new tires into the period, according to the reverse direction of the tire installation, will lead to an early start to tire irregular wear, excessive noise, and will shorten the life of the tread.
Installing a tire / rim assembly onto a truck that fails to balance properly can lead to running difficulties and irregular tread wear. Imbalance will produce a strong vertical force in each rotation of the tire. This vertical force can be sensed by the driver and lead to abnormal changes in tire contact with the ground, resulting in irregular wear and tear. The magnitude of the force depends on the degree of imbalance and the speed of the vehicle. The best time to balance is when the new tire is installed. At this time, you can use the static "bubble type" balance machine or more advanced computer balancer to balance the tire and wheel components.
Tyre and rim lubrication: must be clean and avoid excessive useIt is important to use approved tires to install lubricants. The bead lubricant recommended is a vegetable lubricant and adds a proper proportion of water to the manufacturer's instructions. Do not use antifreeze, silicone oxygen polymer or oil-based lubricant, otherwise it will damage the rubber. A lubricant that does not mix in accordance with the manufacturer's instructions may cause damage to the tire and rim.The main functions of lubricants are as follows:? helps to reduce damage to the tire ring by mounting tools.? by lubricating all the contact surfaces, it helps to reduce the strength of the tyres when they are mounted to the rims.Assist to correct tyre (tire / rim centering ring position), to prevent eccentric installation.
