Description

Annaite 755 315/80 R22.5 154/157M 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 755

• This is likely the brand or model name of the tire. "Annaite" could be the manufacturer, and "755" 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. 315/80

• This indicates the tire's width and aspect ratio.
  • 315: The tire's width in millimeters (315 mm).
  • 80: The aspect ratio, which is the height of the tire's sidewall as a percentage of its width. In this case, the sidewall height is 80% of 315 mm, or 252 mm.
• This size is common for heavy-duty commercial vehicles, such as trucks and buses.

3. R22.5

• 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.
• 22.5: Refers to the rim diameter in inches. This tire is designed to fit a 22.5-inch wheel, which is a standard size for commercial trucks and buses.

4. 154/157

• This is the load index, which indicates the maximum load capacity of the tire.
  • The first number (154) refers to the load capacity when the tire is used as a single tire.
  • The second number (157) 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:
  • 154: Approximately 3,750 kg (8,267 lbs) per tire when used singly.
  • 157: Approximately 4,125 kg (9,094 lbs) per tire when used in a dual configuration.

5. M

• This is the speed rating, which indicates the maximum safe speed the tire can sustain under its load capacity.
• M: Corresponds to a maximum speed of 130 km/h (81 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)
