The clear trend in farming has been that the equipment are getting bigger and so are the attachment. This increases the weight of the tractors, which will then need agricultural tires that can handle the higher loads. Higher loads will mean higher compaction of the soil if this is not handled properly. This is why farmers then to use flotation tires as their main agricultural tires. You want to avoid anything that impacts the yield in a negative fashion.
Since you might be pulling or pushing heavy attachments, it is crucial that you have sufficient traction to avoid slippage. This requires good weight distribution between the tires as well as that you have sufficient weight for the tractor tires to gain traction. So you want to avoid weight as it can cause compaction, but then you need the weight so that you can effectively use the tractor without slippage. If you need to add more weight to your tractor you can use water ballasting, where you fill the tires with water to add weight. Up to 75% water and 25% air, where the 25% air will create the pressure.
A professional tire shop, where they can assure that the tire has a high quality tube, should do ballasting water permeable valves and that there is salt added if you would want to use the tractor during minus degrees. Ballasting without tube can corrode the rim, so it should be avoided. Ballasting can add several hundred kilos of weight per tire, so it is a good weigh to increase the weight if that will benefit your tractors traction on the field.
Tire pressure will also have an impact on the soil compaction where a low pressure will be beneficial on the field, however a too low pressure can damage the tire and too high pressure can negatively impact the yield. Depending on the load that you will need to move, you will need to set the tire pressure accordingly. As changing the tire pressure often, you will need to set it so that it covers your heaviest workload. The tire pressure should be checked frequently as it does vary with outside temperature and you might have some leakage.
As with any heavy tires, you need to make sure that you keep the tires well maintained. Daily wash off is recommended, followed by visual inspection of the tire to check for damage to the tire in form of; bruises, bulges, cuts and cracks. If you notice any deviations, you should consult a tire expert. What you want to avoid is having unscheduled downtime and have maintenance and repairs done while you can still drive your tractor. If you can cater to problems while they are small and easily fixable it tends to save both cost and time, so that you don’t have to get stuck without a tractor while you await it to be repaired.
