Description

Annaite 300 8.25 R20 139/137L provides a detailed specification for a heavy-duty tire, likely designed for commercial vehicles such as trucks or buses. Here's a comprehensive breakdown of what each part of the code means:

1. Annaite 300

• This is likely the brand or model name of the tire. "Annaite" could be the manufacturer, and "300" might refer to a specific series or model within that brand.
• Tires with this naming convention are typically designed for heavy-duty applications, such as commercial trucks, buses, or industrial machinery.

2. 8.25

• This indicates the tire width in inches. A width of 8.25 inches suggests this is a large, heavy-duty tire designed for vehicles that require high load-bearing capacity, such as:
  • Trucks
  • Buses
  • Construction equipment
  • Agricultural machinery

3. R20

• R: Stands for Radial construction, meaning the tire's internal ply cords are arranged radially (perpendicular to the direction of travel). Radial tires are known for their durability, fuel efficiency, and stability.
• 20: Refers to the rim diameter in inches. This tire is designed to fit a 20-inch wheel, which is common for heavy-duty vehicles.

4. 139/137

• This is the load index, which indicates the maximum load capacity of the tire.
  • The first number (139) refers to the load capacity when the tire is used as a single tire.
  • The second number (137) refers to the load capacity when the tire is used in a dual configuration (two tires mounted side by side on the same axle).
• Load Index Values:
  • 139: Approximately 5,750 kg (12,676 lbs) per tire when used singly.
  • 137: Approximately 5,350 kg (11,794 lbs) per tire when used in a dual configuration.

5. L

• This is the speed rating, which indicates the maximum safe speed the tire can sustain under its load capacity.
• L: Corresponds to a maximum speed of 120 km/h (75 mph).
• This speed rating is typical for tires designed for heavy-duty vehicles, which prioritize load capacity and durability over high-speed performance.

6. Key Features of the Tire

• Heavy-Duty Application: Designed for vehicles that carry heavy loads or operate in demanding conditions.
• High Load Capacity: Can support significant weight, making it suitable for commercial or industrial use.
• Durability: Built to withstand tough environments, such as rough terrain, long-distance travel, or heavy usage.
• Traction: Depending on the tread pattern, this tire may provide excellent grip on various surfaces, including asphalt, dirt, or mud.

7. Common Uses

• Commercial Trucks: For transporting goods over long distances.
• Buses: For passenger transport, especially in urban or intercity settings.
• Construction Vehicles: For heavy machinery like loaders, dump trucks, or cranes.
• Agricultural Equipment: For tractors or other farming machinery.

8. Additional Notes

• To ensure optimal performance, always check the manufacturer's guidelines for proper inflation pressure, load limits, and maintenance.
• The tread pattern and compound may vary depending on the intended use (e.g., highway, off-road, or mixed conditions).
