Buying an agricultural tire is not simple at all. Making a mistake can mean less productivity, more consumption, worse wear, and so huge waste of money. The right choice depends on more than the tractor.
Choosing the right tyre for a car or truck is not so easy. But this becomes more complicated if dealing with a tractor. Here the purchase cannot be done lightly at all because, in addition to being particularly expensive, the agricultural tyres have also a strong impact on efficiency and productivity. If the chosen model does not fit the vehicle, use, implements, terrains, and so on, its performance and durability can be badly compromised and, last but not least, even the tractor does not work at its own best. Therefore, quality/price ratio, efficiency, and comfort must be considered as well as some specific technical characteristics: size, speed rating, load index, pressure values.
The right size
Depending on the employment situation - heavier such as plowing or lighter such as sowing, - the tractor can need more or less tractive power. So it is crucial to choose the tyre according to the most usually implemented working.
Generally, tractors’ performances and tyres’ size are proportionally increasing values. A larger tyre compacts the soil less since its footprint is wider. This also reduces slip and fuel consumption. In addition, a bigger tyre can also carry a higher load because the inside air volume is proportional to the carried mass.
Speed and load indexes are further key elements to consider choosing an agricultural tyre. The speed index is the ratio between the load capacity and the driving speed of the tractor. The load index refers to the maximum load that a tyre can carry when moving at the maximum permissible speed and under the conditions specified by the manufacturer. Especially about the load index, it is crucial to consider not only the vehicle they are called to equip but even also the equipment and the implements normally used and, therefore, the impact of their weight on the tractor axles.
The pressure matters
Both the agricultural tyres' efficiency and traction depending on the terrain. On soft soil, a low-pressure tire is better because it squeezes easier and rolls better. However, working on harder soils or driving on asphalt roads, the lowest pressure of the tyre gets to increase the rolling resistance and tread wear and fuel consumption as well.
Finally, pressure also impacts comfort as it directly affects noise and vibrations. An incorrectly inflated tyre produces more noise while rolling and contributes to growing vibrations as well. These elements penalize on-board comfort, and especially vibrations can compromise the driver's health in the long run.
Aeolus proposal: AE74/E7
The Aeolus proposal for the world of agriculture is called AE74/E7. The tyre pattern provides a high grip on soft surfaces. Big contact area design reduces the contact pressure and increases protection to the agricultural land. Then, the special compound provides superior wear resistance. Aeolus AE74/E7 delivers high flotation capability, excellent traction, and superior wear resistance. Aeolus AE74/E7 is available in six different sizes: 560/60R22.5, 600/50R22.5 IMP, 600/55R26.5 IMP, 650/55R26.5 IMP, 710/50R26.5 IMP, 750/60R30.5 IMP.TAGS: Products, Tyre industry, AGRO
