All You Need to Know About Tractor Tires – Technology, Care & Innovation
Why Tires Are Black
Tire rubber is naturally light-colored. It only gets its black color from the addition of carbon black. This additive provides significantly greater protection against abrasion and extends the lifespan – a crucial factor for tractor tires in demanding daily use.
The Development of the Pneumatic Tractor Tire
From Steel Wheels to Modern Tires
The first precursors to modern tractors used steel wheels, which led to significant slippage and loss of traction. In the 1920s, steel lug wheels emerged, offering more traction but causing considerable road damage.
The Breakthrough with Pneumatic Tires
International Harvester developed the first pneumatic tires, though without pronounced lugs. It wasn't until tire manufacturers specifically developed patterned tractor tires in the late 1920s that the agricultural tractor tires we know today came into being.
IF and VF Tires – A Milestone for Agriculture
Depending on the version, IF and VF radial tires offer approximately 20-40% more load capacity than standard tires. Alternatively, with the same load, a significantly lower tire pressure can be used. This protects the soil – especially during heavy-duty operations like slurry spreading.
Tubeless Tractor Tires: More Safety in Use
Tubeless tractor tires are mounted on special rims and lose very little air. An advantage: in case of damage, there is no sudden loss of pressure, which increases driving safety and reduces downtime.
Tractor Tires – A Natural Product with High-Tech Components
Why Natural Rubber is Indispensable
The main component of tractor tires is natural rubber, extracted from the sap of the rubber tree. Synthetic rubber exhibits poorer abrasion behavior and is therefore unsuitable for tractor and truck tires. In total, tires consist of up to 200 different materials.
Origin of Natural Rubber
Thailand is the world's largest producer of natural rubber. Approximately 70% of the global rubber volume is used for tire production.
Why Tractor Tires Wear Even When Stationary
Even during prolonged standing periods, static forces act on the tire, which can lead to deformation. Clean the tires before storage, relieve them as much as possible, and regularly change their position.
Radial or Bias Tires – The Difference
Radial tires are usually more expensive to purchase but offer less slippage, a more even load distribution, and lower fuel consumption. Bias tires wear out faster and are less efficient.
Correctly Measuring and Adjusting Tire Pressure
The Most Common Mistake
Always measure tire pressure when the tires are cold. Warm tires distort the measurement and lead to incorrect settings.
Optimal Air Pressure for Soil & Wallet
The correct tire pressure increases the contact patch, protects the soil, and reduces tire wear. A tire pressure control system allows adjustment directly from the cabin.
Why the Tire Tread is Crucial
Lug shape, tread depth, and tread arrangement determine traction, self-cleaning, and driving comfort. Modern tire treads combine optimal grip with reduced driving noise.
Original Equipment Tires Are Rarely the Best Choice
The initial equipment of a tractor is often a cost-effective compromise solution. A larger or better-suited tractor tire can increase the load capacity by up to 40% – at the same air pressure.
When is a Tractor Tire Considered Worn Out?
Compare the lug height with a new tire. If it is below 50%, the tire should be replaced to ensure performance and safety.
Important Information in the Manufacturer's Manual
The tire manual contains information on load capacity, air pressure, and operating limits. This information is essential for a long service life.
Correctly Calculate Axle Load
The maximum axle load can be determined from the manufacturer's data – a scale is not absolutely necessary.
How to Extend the Lifespan of Your Tractor Tires
Reduce speed on the road, drive slower through roundabouts, and avoid unnecessary friction on asphalt.
