Industrial solid tires are used for low-speed, high-load vehicles and are known for their excellent safety, durability, puncture resistance, tear resistance and economy. They are mainly used for industrial vehicles such as lifting vehicles, towing vehicles and flatbed trucks that operate at low speeds with heavy loads. However, rubber layer peeling can occur during the use of industrial solid tires due to four main reasons:

1，Moisture and impurities in the rubber material, especially fiber rubber, which can be contaminated by rainwater and debris during transportation.
2，Poor insulation of the rubber embryo, resulting in insufficient vulcanization due to temperature fluctuations in the vulcanizer.
3，The tire embryo is formed too early and stored for too long, resulting in uncured center rubber material.
4，Overloading or speeding during use.

In summary, rubber layer peeling is caused by multiple factors. Therefore, it's important to avoid overloading and speeding when using industrial solid tires, and to pay attention to insulation, vulcanization and other aspects.
