Truck tires are an important part of vehicles, and the performance is directly related to the truck's load capacity and wear resistance. Various problems will inevitably occur during driving because of its harsh use environment. There are normal wear and tear, but there are also structural damage.

As a truck driver, these problems must be understood clearly to avoid the situation where the tires are in a state of confusion.

Many of the problems with tires have nothing to do with the quality of the tire itself, because the driver's bad driving habits or external factors cause tire damage.

Here, we can take appropriate preventive measures by analyzing the causes and types of tire wear. Prevention can be done early to avoid unnecessary losses.

To introduce you to some of the most common cases of structural damage and related analysis for reference.

1. The cut of tire ends caused the side drum to burst

Features: The steel wire of the carcass anti-wrap cord of the sub-port is cut off, which causes the radial bulging of the sidewall corresponding to this.

Reason: The spout part was cut by a sharp tool, which caused the carcass anti-cord wire of the spout part to break. Under the action of pressure, the end point of the broken carcass wire continuously stretched and flexed, causing the radial bulge of the sidewall to burst and the wire broke. .

2. Penetration of the sidewall

Features: The tire sidewall is cracked irregularly, with punctures, scratches, or obvious foreign body squeeze marks.

Cause: The side of the tire was punctured by a sharp weapon while driving, or when the twin tires were used together, there was a squeeze between the two tires.

3. Abnormal wear

Features: Irregular wear of the crown.

Reasons: The tires are not regularly replaced, the vehicle condition is poor, the directional tires are not regularly installed, and the rims are not suitable.

4. Stabbing blasting

Features: Fan-shaped blasting on the sidewall, with obvious stab wounds on the crown corresponding to the blasting.

Cause: The crown part was stabbed and the carcass cord was punctured, causing a crack in the carcass ply from inside to outside, and bursting from the crack under the action of pressure.

5. Peeling delamination

Features: Sharp objects puncture the belt steel wire of the crown, and the shoulder glue is detached from the steel belt.

Reason: Sharp objects stabbed the belt steel wire at the crown of the tire, causing water, ash, sand, etc. to infiltrate.

6. Crown burst

Features: The crown is a strong tearing blast.

Reason: The tire is driving under the condition of overload, high speed and high air pressure, and it is strongly impacted by obstacles, causing blasting.

7. Shock burst

Features: The crown is blasted, corresponding to the inner "I" shape split.

Cause: The crown is cracked due to uneven road surface or strong impact of obstacles while driving.

8. Side tire abrasions

Features: The shoulders are circumferentially abraded, and the carcass cord is visible.

Cause: The road was abraded by hard objects on the road, and the use conditions were extremely bad. The auto parts pressed against the side of the carcass, causing circumferential mechanical abrasions.

9. Hard pattern

Features: The tread pattern of the tire is punctured by sharp objects, and a belt layer can be seen at the damaged area.

Cause: Driving on a bad road, the tread is cut by a bad weapon, or the crown rubber is scratched, causing the groove to crack or the crown rubber to fall off.

10. Piercing Blasting

Features: "Zipper"-shaped blasting on the sidewall, with obvious thorns and scratches on the blasting or corresponding crown.

Cause: The tire sidewall or corresponding crown was punctured, causing the steel cord of the carcass to break, the strength decreased, and the blast occurred.

11. Pierce

Features: Puncture of the crown, partial rupture of the cord in the tire and separation from the carcass.

Cause: When driving, the road surface weapon pierced the carcass, causing local steel wire breakage.

12. The carcass cord is broken

Features: The carcass cord in the tire is broken throughout the week.

Cause: Tires are crushed and fractured due to insufficient air pressure.
