Fault 1. Excessive wear of tire crown
There are 4 reasons for excessive tire crown wear.
①The driving wheel slips. The load of the loader is too large, and the relative adhesion of the tires is reduced, causing excessive wear of the tire crowns. There are obvious traces of carbon black and scratches on the drive wheels.
②Insufficient tire pressure. This will cause the load on the loader to increase and the tires to deform excessively, which not only increases the driving resistance of the loader and causes the tire temperature to rise, but also increases the wear area of the tires when driving, causing premature crown wear. Frequent steering while the loader is operating can also lead to increased wear on under-inflated tires.
③The tire pressure is too high. It is easy to reduce the contact area between the tire and the ground, resulting in increased local wear of the tire crown.
④Poor road surface smoothness. The loader has been driving on complex terrain such as rocks and sand for a long time, and its hard edges and corners penetrate the colloid on the surface of the tire crown to form wounds.
Fault 2: The tire crown colloid falls off irregularly
First of all, the tire colloid falls off, and the abnormal wear of the tire crown will be further aggravated. The causes of colloid shedding mainly come from two aspects. First, the road conditions are poor. Complex terrain and stones will penetrate into the tire crown colloid and form deep wounds. In addition, the drive wheels will slip, which will inevitably cause some of the colloid to fall off in chunks.
Second, the original carcass of retreaded tires has flaws (such as penetration wounds, workmanship defects, inferior materials, etc.), and the crown has poor wear resistance and will naturally fall off under the action of external forces.
Fault 3. Tire puncture
When the loader is driving, angular gravels, nails and other slender materials that protrude from the road surface can easily penetrate the tire body and injure the inner tube if the angle is right, causing damage to both the inner and outer tubes.
Fault 4. Tire pinching
Tire pinching refers to the folding phenomenon of the inner tube in the inner cavity of the outer tire. When replacing tires, if a large-sized inner tube is used or the inner tube is inserted into the inner cavity of the outer tire or for other reasons, the inner tube is not properly distributed in the inner cavity of the outer tire, which will cause tire pinching. The inflated tire will be squeezed repeatedly during driving. Cause inner tube damage.
