12.00-R20-18PR 154/149K HO313 Onyx

The 12.00-R20-18PR 154/149K HO313 Onyx is a robust, high-performance radial tyre designed for heavy-duty commercial vehicles, including trucks, buses, and other vehicles that require high load-bearing capacity. Built for durability and reliability, this tyre performs well on both on-road and off-road conditions, making it ideal for a variety of demanding environments. Here’s a detailed breakdown of its features:

1. Size:

• 12.00 refers to the width of the tyre in inches (12 inches).
• R20 means the tyre fits a 20-inch rim and is of radial construction, which provides greater strength, stability, and improved fuel efficiency compared to bias tyres.

2. 18PR (18 Ply Rating):

• 18PR indicates that the tyre has an 18-ply rating, meaning it is constructed with 18 plies, enhancing its durability, load-carrying capacity, and resistance to rough road conditions. This high ply rating ensures the tyre can withstand heavy-duty use, especially for commercial vehicles that carry heavy loads.

3. Load Index (154/149):

• 154/149 is the load index, which denotes the maximum weight the tyre can support in both single and dual configurations:
  • 154 means the tyre can carry up to 3,100 kg when used as a single tyre.
  • 149 means the tyre can carry up to 2,900 kg when used as a dual tyre.
• This ensures the tyre is capable of handling the heavy loads typically encountered by commercial vehicles, making it ideal for long-haul trucks, buses, and other high-load vehicles.

4. Speed Rating (K):

• The K speed rating indicates that the tyre is rated for a maximum speed of 110 km/h (68 mph). While the tyre is primarily designed for heavy-duty load-bearing and off-road conditions, it can still maintain a moderate speed on highways.

5. Model (HO313 Onyx):

• The HO313 Onyx is a high-performance model designed to deliver durability, stability, and reliability in a variety of environments. It is ideal for vehicles operating on highways, construction sites, and off-road terrains where heavy loads and challenging driving conditions are common.

6. Tread Design:

• The tread design of the HO313 Onyx is engineered for optimal traction, stability, and long-lasting performance. The deep grooves and strong tread blocks offer excellent grip on both dry and wet surfaces, reducing the risk of hydroplaning and improving braking performance in all conditions. It is designed for heavy-duty use on various surfaces, including highways and rugged, off-road environments.

7. Construction:

• The HO313 Onyx is built with radial construction, which provides enhanced durability and stability, especially under heavy loads. The radial design also contributes to better fuel efficiency, improved ride comfort, and reduced tyre wear, making it ideal for long-distance commercial vehicle operations.

Summary:

The 12.00-R20-18PR 154/149K HO313 Onyx is a top choice for commercial vehicles, trucks, and buses that require a robust tyre capable of handling high loads over long distances. With its 18-ply rating, high load index, and durable construction, it is built to withstand tough conditions, whether on paved highways or rough off-road surfaces. The HO313 Onyx provides a reliable, high-performance solution for vehicles that need strength, durability, and traction for demanding applications.
