The size selection principle of industrial tires is mainly based on the following aspects:

1. Requirements of the vehicle itself

User specification: Tire sizes are selected according to the specific needs of the user or the recommendations of the vehicle manufacturer.

Standard approval: Select tire sizes that comply with JIS and Japan Automobile Tire Association and other authorities.

2. Operating conditions and working conditions

Load capacity: The load index of the tire must be able to meet the actual load requirements of the vehicle. Different tire sizes correspond to different load capacities, so the appropriate tire size should be selected according to the load capacity of the vehicle.

Speed rating: The speed rating of a tire indicates the maximum speed that the tire can safely withstand. For industrial vehicles that are often on highways or need to travel at high speeds, choose tires with high speed grades and ensure that the tire size matches the vehicle speed.

Road condition adaptability: Different road conditions have different requirements for tires. For example, industrial vehicles driving in bad road conditions should choose tires with good wear resistance and puncture resistance, and consider increasing the width and thickness of tires to improve grip and stability.

Traction and handling: The size and pattern of the tires affect the traction and handling of the vehicle. When choosing a tire size, the operating environment and needs of the vehicle should be considered to ensure that the tire can provide adequate traction and handling.

Third, the understanding of tire parameters

Tire width: Usually expressed in inches or millimeters, determines the area of contact between the tire and the ground. Wider tires provide better stability and grip, but also increase rolling resistance and fuel consumption.

Flat ratio: indicates the ratio of tire section height to width. A higher flat ratio means that the tires are thicker, providing better cushioning and comfort; The lower flat ratio makes the tires thinner, which is conducive to the vehicle's handling and responsiveness.

Rim diameter: The diameter of the inner rim of the tire, usually in inches. The rim diameter determines which vehicles the tire can be mounted on.

4. Precautions

Do not mix different types of tires: do not mix different types, specifications, structures, and patterns of tires on the same axle to avoid adverse effects on tire life.

Choose the right inner tube and gasket: Make sure that the inner tube and gasket match the tire and vehicle, and check their condition regularly to ensure safety.
