The standard for industrial tire replacement is mainly based on five core indicators: wear level, structural damage, signs of aging, service life, and operational abnormalities, to ensure operational safety and equipment stability.

1. Tread Wear to Limit

Tire treads have wear indicators. Tires must be replaced when the tread wears down to the level of these indicators.

When the measured tread depth is less than 1.6 mm, grip and water drainage performance decrease sharply, especially on wet surfaces where slippage is likely.

While solid tires don't have pressure issues, excessive wear can lead to uneven load distribution, increased vibration, and reduced vehicle stability.

2. Structural Damage

Bulges or blisters: Indicate that the internal cord layers have broken, posing a risk of sudden rupture. Tires must be replaced immediately.

Cracks, cuts, or punctures: Damage to the tread or sidewall exceeding 2 mm in depth, especially when the cord layers are exposed, is irreparable and requires immediate replacement.

Deformation or dents: Irregular deformation caused by overloading or impacts affects rolling balance and accelerates equipment wear.

3. Severe Rubber Aging

Even if the exterior appears intact, a thorough inspection is necessary after 3-5 years of use. Rubber will naturally harden, become brittle, and develop fine cracks, reducing its impact resistance.

High temperatures, direct sunlight, and oily environments accelerate aging; regular cleaning and avoiding prolonged exposure to direct sunlight are recommended.

4. Abnormal Performance During Operation

Noticeable shaking, yaw, or unusual noises while driving may indicate tire imbalance or internal damage.

If solid tires show signs of softening or collapse, it indicates damage to the internal filling material, rendering them unable to bear loads.

Frequent leaks or inability to maintain pressure in pneumatic tires suggest damage to the airtight layer, requiring professional inspection to determine replacement.

5. Reaching Service Life or High-Intensity Service Cycle

Under high-intensity conditions such as 24-hour operation and heavy-duty handling, even if the exterior appears good, an overall condition assessment is recommended every 3 years.

Most industrial solid tires are designed for a lifespan of 3–5 years. After that, preventative replacement is recommended to avoid sudden failures that could affect production safety.
