The main function of heavy-duty tyres is bearing car body and buffering external shocks, realizing the contact with road surface and ensuring rideability. Because of its particularity, heavy-duty tyres should possess not only higher carrying ability, traction and cushion performance, but also good wearproof, flexing resistance, and lower rolling resistance and heat generation. It is no small expenditure for annual tyre replacement in vehicle maintenance. Many truck drivers must be concerned about this problem. So, let's talk about new tips of tyre maintenance today.

1. Tyre specifications matter in purchase

Please pay attention to the specification marked on the tyre in purchase. For example, 1200R20 (there are many other labels on the tyre, such as tyre pressure, speed, etc.). 1200 represents 12 inches cross section; R is radial structure, generally full steel wire; 20 is for assembling hubs of 20 inches. Look for truck capacity, road conditions, etc. when purchasing tyres. Hereby, it's suggested that truck drivers choose better heavy-duty tyres if economic is possible, not only with safety and guarantee in after service, but also lower cost.

2. Essential to be anti-sticking before using inner tyres.

Many users may not pay attention who will assemble the tyre and use it directly. It’s found that the inner tyre and outer tyre are firmly stuck together when the tyre gets flat. Although the inner tyre can be removed with struggle and try, it is only a part of it, with the rest stuck to the outer tyre. As a result, it requires that heavy-duty tyres be separated before being assembled. Usually it's better to strew talcum powder over the inner tyre and outer tyre to separate them.

3. Quality assurance on wheels

Choose good quality wheels with good tyres. When selecting wheels, we must pay attention to its size and quality. After removing impurities from the wheel (do not leave any debris inside) and applying soapy water to the circumference, the combination of tyres is performed. You'll also need a suitable tyre pad to reduce wear on your tyres and rims.

4. Required standard of tyre pressure, reasonable inflation and loss reducing

Every heavy-duty tyre is marked with tyre pressure value, but there is still unreasonable inflation for overload, which is not allowed. Too high or too low tyre pressure will increase tread wear, or even cause a flat tyre. According to the load of each shaft, each tyre can be inflated reasonably whose tyre pressure is increased by 5%~10%. Significantly, tyre pressure of coaxial tyres must be consistent. While in the course of the daily driving, it's necessary to check regularly to ensure normal use of tyres. The resistance between tyres and the ground will result in rise of tyre temperature and pressure, easily causing a flat tyre. Aulice considers it a good solution to inflate the tyre with nitrogen.

Note: Please protect yourself in the process of inflating tyres, which can be very dangerous!

5.  Crucial to be dynamically balanced

Anyone who has ever driven a car knows that tyres need to be dynamically balanced when repairing it. But it's wrong that most people see no need for dynamic balance of truck tyres. In terms of technology, the density of wheel rim and heavy-duty tyre are not precisely the same, which causes each part to generate different centrifugal forces in high-speed operation. The forces will transmit to the tyre, causing uneven tyre wear, and to the body, causing body jitter. Aulice recommends making tyres dynamic balance after each repair for the comfort and safety of driving and reducing costs.
