Tractor tires are the only components of agricultural machinery that come into contact with the ground. Their type and specifications directly affect the tractor's traction efficiency, maneuverability, stability, and overall operational economy. Choosing the right tires is crucial for improving work quality, protecting soil structure, and extending equipment lifespan. This article will systematically explain the model coding rules for tractor tires, provide an expanded table of common specifications and parameters, and offer a purchasing guide based on actual working conditions.
Detailed explanation of tractor tire model numbering rules
Tractor tire sizes are typically represented by a combination of numbers, letters, and hyphens, such as the classic "16.9-28" and "18.4R30". This code is not randomly arranged but standardized to convey key dimensional information about the tire.
Basic format A-B: This is the most common representation.
A (the first number): Represents the tire's section width in inches. For example, "16.9" indicates a tire cross-section width of approximately 16.9 inches.
- (connector): Traditionally indicates a bias-ply tire structure.
B (the second number): Represents the diameter of the compatible rim in inches. For example, "28" indicates that the tire needs to be mounted on a 28-inch diameter rim.
Meaning of the letter suffixes:
R: Represents radial tires. Their carcass cords are arranged in the direction of the Earth's meridians, offering advantages such as low rolling resistance, a large contact area, better wear resistance, and improved comfort, as seen in examples like "18.4R30".
