In the Vietnamese truck tire market, the 7.50 size is a popular choice for light and medium-duty trucks. In particular, 7.50 bias ply truck tires are known for their durability and load-bearing capacity, suitable for various operating conditions. However, to make the most suitable decision when buying 7.50 truck tires, owners need to understand detailed information about this size, different ply structure types (bias ply, radial), advantages, disadvantages, and reputable brands on the market. This article from Xe Tải Mỹ Đình will provide a comprehensive overview of 7.50 bias ply truck tires, helping you make smart and optimal choices for your truck.
What are 7.50 Truck Tires? Decoding Technical Parameters
To understand 7.50 bias ply truck tires, you must first understand the meaning of the technical parameters printed on the tire. The 7.50 size is one of the most important factors, indicating:
- 7.50: This is the width of the tire surface in contact with the road, measured in inches. 7.50 inches is equivalent to approximately 190mm.
- Difference between “Bias Ply” and “Radial”: The original article refers to 7.50R16 tires, where “R” represents the radial structure. 7.50 bias ply truck tires do not have an “R” in the symbol. The traditional bias ply structure uses multiple layers of nylon or polyester plies stacked diagonally, creating characteristic robustness and load-bearing capacity. Meanwhile, radial tires have steel belts running perpendicular to the tire’s circumference, providing driving stability and durability on the highway.
Usually, after the width size 7.50, there will be information about the tire diameter and structure, for example:
- 7.50-16: 7.50 bias ply truck tires, suitable for 16-inch rims. The “-” sign indicates a bias ply structure.
- 7.50R16: 7.50 radial truck tires, suitable for 16-inch rims. The letter “R” represents the radial structure.
In addition, there are other important parameters on the tire, such as:
- PR (Ply Rating): Ply rating index, for example, 14PR indicates that the tire has 14 plies, showing the tire’s load-bearing capacity and durability. The higher the PR number, the stronger the tire and the better it can bear loads.
- Load and Speed Index: For example, “116/114L” indicates the maximum load capacity (116 for single tires, 114 for dual tires) and the maximum allowable speed (L corresponds to 120 km/h).
- Tire Tread Pattern: Longitudinal tread, horizontal tread, mixed tread… Each type of tire tread is suitable for different terrain conditions and purposes.
