How to choose the trailer tire to extend the service life?

Trailer as the mainstay of the freight industry, its transport conditions are relatively complex, tires as the only parts in contact with the road during the driving process of the trailer, need to bear a variety of deformation, load, force and high and low temperature effects under the conditions of high-speed, heavy load, rain and snow, sand and gravel, so it is a huge consumable. Good driving skills can often help the owner to extend the life of the tire.

This issue of DARO trailer axle simply summarizes the relevant matters in the selection of trailer tires for your reference.

1, the air pressure to meet the standard

When the tire pressure is lower than the standard value, the shoulder wear increases. When the tire pressure is higher than the standard value, the tire ground area is reduced, the unit pressure is increased, the tire tread middle wear is increased, and the tire rigidity is increased, so that the dynamic load on the wheel is increased, and the tire body is easy to burst. Therefore, before using the vehicle, ensure that the tire pressure meets the standard.

2, no cracks in the tread

Check the tire surface regularly for cracks, deformation, etc. Tire pattern trench due to driving wear gradually become shallow, if the wear is serious, the tire pattern trench will lose the role of drainage anti-skid, the performance of the decline in high-speed operation, affecting driving safety. In addition, pay attention to the timely removal of small stones in the groove.

3, parking site selection

Try not to stop on potholes, gravel roads, uphill, do not let the tire contact or close to petroleum products, acids or other easy to cause rubber deterioration. Also, try not to turn the steering wheel after parking.

4, do not water heat dissipation

Especially when the vehicle has just finished running and the tires are in a high temperature state, do not pour cold water directly to cool down, otherwise it is easy to damage the tires.

5, try to avoid sudden braking

Enhance predictive driving during vehicle use, try to avoid unnecessary sudden brakes, so as to avoid tire and road drag accelerated tread wear. The car should not start too fast.

6. Select the driving route on special sections

When driving in the highway maintenance construction area, the method of selecting the road surface at low speed should be used to avoid excessive impact on the tire; Driving on uneven roads, try to choose a relatively flat road surface, reduce the impact of tires and roads, slow down and avoid tire bumps and strong vibrations; When passing through the muddy lot, you should choose a more solid and not easy to slip through the place, so as to avoid tire sinking, idling in place, and severe heat generation causing tire and tire side damage.

7, control the speed

When the driving vehicle encounters a turn, it should be properly slowed down according to the road conditions and turning radius of the bend, so as to avoid the accelerated wear of the unilateral tire caused by the inertial force and centrifugal force; When the vehicle goes downhill, it should control the appropriate speed according to the size and length of the slope and the road conditions. When the vehicle stops on the way and stops at the station, it should develop the habit of safe taxi.

When choosing tires, owners should fully consider vehicle performance, driving habits, driving routes, climatic conditions, etc.

1, the steering wheel generally selects four longitudinal patterns, which can fully reduce the resistance of the trailer when driving, especially when driving on curves, which can further increase the guidance and anti-sideslip ability.

2. The special tire is mainly made of four longitudinal patterns, which can enhance the ability to resist transverse scratching. The steel wire strap structure inside the special tire is also more special, with stronger anti-puncture, anti-collision and anti-impact performance.

3, the driving wheel generally chooses four or five longitudinal stripes with dense horizontal stripes, these patterns can improve the tire's passability, to a certain extent, improve the load-bearing capacity, extend the service life of the tire.

4, general purpose tires are recommended to choose three longitudinal lines, because the area of contact with the ground is larger, the shoulder is wider and thicker, and it has better wear resistance.

5, try to choose the flower tire, that is, the longitudinal arrangement of the pattern of tires, which can minimize the resistance of the vehicle when driving, reduce fuel consumption and reduce costs, combat lateral scratching, and reduce the probability of tire slippage.

6, in the tire model, the general long-distance, good road conditions with vacuum tires; Short-distance, poor road conditions with more wire tires or vacuum tires; Low flat plate, three-line six-axis general vacuum tire steel wire tire; The skeleton trailer can choose large single tires.

7, if most of the road driving, straight hook, wide ditch pattern drainage is good, can also reduce fuel consumption, avoid water skiing phenomenon; If the secondary road driving more, you can choose a higher wear resistance of the tire; If there are more mixed roads, it is recommended to choose a mixed pattern, that is, a medium flower.
