The overall durability of domestically produced agricultural tires has reached the practical standards for mainstream operating scenarios. They fully meet the operational needs of most farms in China under normal dryland and paddy field conditions, and the wear resistance of some high-end radial tires has caught up with imported products of the same level.

1. Core Data on Actual Durability

Ordinary bias-ply herringbone tires: Continuous operating life in normal dryland conditions can reach 1500-2000 hours; after 200 hours of high-intensity operation, the tread wear rate is less than 1.5%.

Steel-belt radial agricultural tires: The industry generally refers to a service life of 3-8 years; normal mileage can reach 30,000-100,000 kilometers; with proper maintenance, it can be extended to 8-10 years.

Three-wheeled vehicle-specific wear-resistant tires: Actual tread wear rate measured at 20,000 kilometers is less than 0.03 mm/km; 94.4% of users reported that "no replacement is needed after one season."

Deep tread pattern R-1W series: Compared to ordinary R-1 tires, the service life is directly extended by more than 20%, suitable for heavy-duty autumn harvest operations.

2. Durability Shortcomings and Applicable Limitations

In extreme heavy-load and year-round gravel road operation scenarios, the tear resistance of some low-priced domestic tires still lags behind that of high-end imported VF flexible tires.

To reduce costs, some small manufacturers use a higher proportion of recycled rubber in their products, which significantly accelerates aging after prolonged exposure to sunlight, potentially leading to dense sidewall cracks within about 5 years.

Under the long-term highway transport conditions of high-horsepower agricultural machinery, ordinary bias-ply domestic tires generate heat more quickly, making them prone to abnormal wear over continuous long-distance driving.

3. Usage Techniques to Maximize Durability

Strictly follow the agricultural machinery's instruction manual to adjust tire pressure. A tire pressure deviation exceeding 20% will increase tire wear rate by more than 30%.

Rotate tires every 10,000-20,000 kilometers to ensure more even tread wear and extend overall lifespan by 1-2 years.

Avoid prolonged pressure and exposure to direct sunlight during idle periods. Even tires with low mileage should be replaced if stored for more than 8 years.
