What Do Agricultural Vehicle Tire Models Represent?

Agricultural vehicle tire model markings usually contain multiple parts, each with its own specific meaning. For example, a typical tire model is 215/70R15, where:

215 represents the tire's section width in millimeters. This number represents the width of the tire, and for agricultural vehicles, wider tires generally provide better stability and grip. 1
70 is the aspect ratio, which is the ratio of the tire's sidewall height to the tire's section width. This number represents the percentage of the sidewall height to the tire's width. In agricultural vehicles, the proper aspect ratio is critical for load capacity and driving stability.
R is the abbreviation of Radial, which means that the tire is a radial layer structure, that is, a radial tire. This structure has better load capacity and high-speed stability than bias tires.
15 is the outer diameter of the rim in inches. This number determines the size of the wheel that the tire is suitable for.
In addition, agricultural vehicle tires may also include other information, such as load index and allowable speed code, which are critical to ensure the safe use and performance of the tire. For example, the model of a tractor tire may be more complex, including information such as section width, aspect ratio, rim diameter, etc., which all need to be selected based on the specific vehicle and usage conditions.
