Description

Annaite 700 315/80 R22.5-20 157/154K 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 700

• This is likely the brand or model name of the tire. "Annaite" could be the manufacturer, and "700" 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. 20PR

• PR: Stands for Ply Rating, which indicates the tire's strength and load-carrying capacity. Historically, this referred to the number of fabric plies in the tire, but modern tires use fewer, stronger plies.
• 20PR: A high ply rating, indicating that this tire is designed for heavy loads and tough conditions. It is suitable for commercial vehicles carrying significant weight or operating in demanding environments.

5. 157/154

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

6. K

• This is the speed rating, which indicates the maximum safe speed the tire can sustain under its load capacity.
• K: Corresponds to a maximum speed of 110 km/h (68 mph).
• This speed rating is typical for tires designed for heavy-duty vehicles, which prioritize load capacity and durability over high-speed performance.

7. 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.

8. 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.

9. 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).
