Heavy truck tyres are the feet of heavy trucks, carrying the weight of the entyre body; it is the only part in contact with the ground, and it is an important part to ensure the safe running of heavy trucks. Sometimes we will use “well-leveraged" to describe the situation that a great task is accomplished with a few efforts, and it is the same truth that the small tyre can carry the car body of ten or dozens of tons.

So what supports heavy truck tyres? It is the air that carries a truck full of goods. Without air, heavy truck tyres carry almost nothing. Therefore, the more air in the tyres is, the more pressure is, and the more weight the truck can carry. But is the tyre pressure the higher the better?

1. What is standard pressure?

The standard pressure is the pressure marked on the tyre by tyre manufacturers. The tyre pressure provided by the manufacturer is based on the conclusion drawn after many tests, so it is never wrong to inject pressure according to the manufacturer's requirements. The standard pressure set by the tyre manufacturer is generally clearly indicated on the tyre side.

2. How much should heavy truck tyres be pumped?

There may be differences in tyre pressures between different heavy truck tyres, but there may also be differences in standard tyre pressures for the same tyre products. Tyres with the same specifications, different levels and different load index have correspondingly different standard tyre pressures. You should first look at the standard pressure on the tyre side before pumping up each tyre!

For tyre shops, too high tyre pressure increases the risk of a flat tyre. The accident of tyre explosion in inflating happens every year, which is also the last thing people want to encounter. In addition, too high or too low tyre pressure will cause high fuel consumption, abnormal tyre wear, vehicle bumping and other problems.

3. The harm of too high or too low air pressure

Too high or too low tyre pressure will cause a flat tyre, and the most direct feeling of too high tyre pressure is that the vehicle bumping increases in driving and the comfort decreases; too high pressure will lead to abnormal wear of heavy truck tyres, and mainly aggravate the wear of the middle part of the tyre running surface. Standard tyre pressure is important for heavy truck tyres whether in economy, comfort, or safety aspect.

The owners of heavy truck tyres often ask the tyre shop to pump more air into the tyre. Since the tyre shop knows the harm of the flat tyre and understands the influence of high tyre pressure on the vehicle, it must dissuade the owners and try to regulate the market according to the regulations of tyre manufacturers.
