Given that improper lead can cause extremely rapid wear to your tractor tyres, you may rightly wonder whether this type of problem will be covered by the manufacturer’s warranty. The concept of mechanical lead is generally misunderstood and is linked to the varying rotation speeds of different sized tyres at the front and the rear on four-wheel drive tractors. You cannot consider that a correct...
Tight control of fuel consumption is at the heart of agricultural concerns, since fuel can represent up to 30% of your annual operating budget. Many factors influence this consumption; speed naturally, but also the type of land, the weather conditions, the choice of crop growing methods and habits in terms of machine use. But among these elements, the role of the tyre is often underestimated. In...
When you compare different agricultural tyre models with the same dimensions, you don’t get the same soil footprint or the same work results. The impact of the tyres on soil compaction is different, slip may be correct or excessive, traction may be low or powerful… While it is difficult to gauge the quality of an agricultural tyre simply by looking at it, a lot can be learned by rapidly...
The contact area with the ground beneath the four tyres of a tractor is relatively low, in proportion to the size, the load and the power of the machine. Yet it is this small area that will allow power to be transmitted to the ground and generate the work effort, the traction of heavy implements, acceleration and torque. There are only a few lugs in contact with the ground at the same time and...
Changing your tyres to adapt your tractor to its real use on your farm is extremely positive; it will optimise your vehicle and improve your efficiency. Whether it’s an increase in the volume of your tyres to carry more load or having the same width of tyre at the front as at the rear for better tilling, or to avoid compacting your soil, you should pay attention to the impact of the dynamic...
You are aware that lead plays an important role in the efficiency of your tyres and that failing to take this aspect into account has consequences in terms of the behaviour of your tractor at work. However, it is not easy to spot incorrect lead, as this is certainly one of the most difficult mechanical settings to grasp. For 4WD tractors with different size wheels, the lead ratio is linked...
Mixed crop-livestock farming work requires more versatile tyres for your tractors than field crop farming alone. During manoeuvres in the farm courtyard, your tyres effectively face a tough task on hard ground with a significant load transfer to the front of the machine if you use a front loader. You also have to work in the fields to complete your activity and your tyres must once again adapt...
You have noticed abnormal wear to your agricultural tyres, or your tractor’s manoeuvrability doesn’t seem normal when you are working: too much slip, the rear axle pushing too much or the front axle that isn’t catching enough… it is quite possible that you are seeing the effects of an unsuitable lead ratio. The lead ratio is often considered as just a mechanical piece of data despite the fact...
You are equipped with VF tyres, but like a large number of users with this top-of-the range equipment, you have got into the practice of working most of the time with an average inflation pressure to simplify life and not have to think about your tyres. However, if you use your tyres to their full capacity, you can gain much more than just peace of mind, with real financial savings, in fuel and...
