Semi-trailers can be matched with a variety of tire specifications, from 8.25R steel tires to 12.00R steel tires, but generally only 8.25R steel tires, 10.00R-12.00R steel tires, and 11R-12R tubeless tires are used. Speaking of the service life and cause for failure of tires, in addition to the quality, use management is also one of the main factors. In order to achieve the purpose of safety and economy, which are subjected to tire failure and tire service life respectively, correct use and management is the only way and cannot be ignored.

  • Semi-trailers can be matched with a variety of tire specifications, from 8.25R steel tires to 12.00R steel tires, but generally only 8.25R steel tires, 10.00R-12.00R steel tires, and 11R-12R tubeless tires are used.

  • The 8.25R steel wire tires are only used on heavy-duty lowbed semi-trailers. Other types of semi-trailers basically use 11.00R-12.00R steel wire tires and 11R-12R tubeless tires. Although 10.00R steel wire tires are also used on semi-trailers, there are fewer types. This can be understood by looking at the usage on the road and the announcement of the manufacturer.

  • Correct use of semi-trailer tires can prolong the service life of semi-trailer tires.

Details of How to Prolong Service Life of Semi Trailer Tires

Speaking of the service life and cause for failure of tires, in addition to the quality, use management is also one of the main factors. In order to achieve the purpose of safety and economy, which are subjected to tire failure and tire service life respectively, correct use and management is the only way and cannot be ignored. Details are as follows:

 

Internal Pressure Management of Semi Trailer Tires

Influence of Insufficient Internal Pressure

A. Due to the expansion of buckling deformation, the temperature inside the tire increases so that the strength and bonding force of the carcass material decrease, which causes the tread rubber or the cord layer to separate or even burst.

B. Excessive buckling is prone to cracks and curtain yarn breaks. This could happen to both anti-skid grooves and sidewalls.

C. Due to excessive shaking and abnormal friction between the tire lip and the steel ring, the tire lip may be damaged or even burst.

D. When the tire lip and the steel ring are not closely fitted, the inner tube valve nozzle may be displaced and damaged.

E. It is easy to generate standing waves and vibrate. The rotation resistance is large and the heat generation and strength decrease.

F. It will accelerate the wear of the tire shoulder and affect the life of the tire.

G. The internal pressure is low, the tire rotation resistance is increased, and therefore more fuel is consumed.

Load Management

1. The influence of excessive load

A. High load and low internal pressure create similar environment for the tire. Thus, the failure that may occur at low internal pressure will also occur at high load so special attention must be paid.

B. When the load is too high, it is easy to cause abnormal wear and affect tire life.

C. When the load is too high, it increases tire rotation resistance and consumes more fuel.

2. In addition to affecting the driving safety, the wrong loading method will also cause overload for the tires.

Speed Management

1. The impact of high speed on semi trailer tires:

A. As the speed increases, the driving force, braking force, and centrifugal force will increase relatively resulting increased tire and road slippage. In this case, the wear will be accelerated, that is, the tire life will be reduced.

B. When the speed is increased, the flexion and extension activities of the tires increase, which increases the heat generation and causes failures.

2. The speed increases, the rotational resistance and air resistance increase resulting unnecessary increase in fuel costs.

3. Speed and braking distance

When the driving speed is increased to as twice as much, the braking distance will be four times as much as before. In other words, if the vehicle speed is 50km/h and the emergency braking distance is 25 meters, when speed is increased to 100km/h, the emergency braking distance will be 100 meters.

 

Double Wheel Management

1. The load of the second tire of the double wheel may not be equal due to the following reasons:

A. Drainage design of pavement (arc)

B. The uneven road surface.

C. The tire inflation pressure is unbalanced.

D. The outer diameter of the tires is not the same.

Therefore, when the tire is installed on the double wheel, its load must be moderately reduced, thereby reducing the possibility of failure.

2. When the double wheel is installed, the wear of the tire with a large outer diameter will be poor. Therefore, the outer diameter difference of the double wheel should be as small as possible.

3. When there is a difference in outer diameter between the double wheels, the smaller outer diameter should be installed on the inner side.

Low internal pressure and high load can easily reduce the distance between the multiple wheels. It may even cause them touching together. This situation will cause poor heat dissipation of the tires and failure.

Tire Position Exchange

1. The front wheel is prone to partial wear due to the influence of lateral resistance and braking device. The rear wheel is more fatigued due to the heavy load, especially when it is the driving wheel. Therefore, if the tire position is properly exchanged in a timely manner, the uneven wear and fatigue can be averaged out and the life of the tire can be improved.

2. An example of the tire position exchange method is as follows:

The patterns of the drive shaft and the guide shaft are different. Generally, do not replace them at will, but mainly for high-speed vehicles. The requirements for the patterns are not too strict and they can be replaced under the guidance of technicians.
