Understanding Tractor Tires – Knowledge That Saves Money
Finding the optimal tractor tire is anything but easy. At the same time, it represents a significant investment for any agricultural business. In this guide, Interpneu AG presents 20 exciting and often unknown facts about tractor tires – from material science to proper maintenance.
Basics & History of the Tractor Tire
Why Tires Would Actually Be White
Natural rubber is naturally light-colored. It is only through the addition of carbon black that the tire gets its black color. This additive protects the tire from rapid abrasion and significantly increases its lifespan.
The Journey from Steel Wheels to Air-Filled Tires
The first agricultural traction engines in the 19th century used steel wheels. These caused high slip and enormous power losses. In the 1920s, steel lug wheels were initially used, which offered more traction but severely damaged roads.
The Birth of the Modern Tractor Tire
International Harvester was the first to develop air-filled tires for tractors. It wasn't until the late 1920s that these evolved into actual agricultural tractor tires with lug treads – the basis of our modern tractor tires.
Modern Tire Technologies & Benefits
IF and VF Tires – A True Revolution
Compared to standard tires, IF and VF radial tires offer approximately 20 to 40 percent higher load capacity. Alternatively, you can operate at significantly reduced tire pressure with the same load – a clear advantage for soil protection, especially with heavy implements such as when spreading slurry.
Tubeless Tractor Tires – More Safety in Operation
Tubeless tires are mounted on special tubeless rims. Due to their design, they lose very little air. In case of damage, there is no abrupt pressure loss – this significantly increases driving safety.
Material & Origin
A Natural Product with High-Tech Components
Tractor tires consist primarily of natural rubber, which is obtained from the sap of specific trees. Synthetic rubber is less abrasion-resistant and therefore unsuitable for tractor and truck tires. Overall, modern tires are composed of up to 200 different materials.
Where Does Natural Rubber Come From?
Thailand is the world's largest producer of natural rubber, with approximately 3 million tons annually. About 70 percent of global rubber production is used for tire manufacturing.
Wear, Storage & Maintenance
Why Tires Age Even When Stationary
Even during storage, static forces act on the tire, which can lead to deformation. Clean the tires before storing them, store them upright, relieve them as much as possible, and regularly change their position.
Radial Tires vs. Bias Tires
Radial tires are more expensive to purchase but offer advantages such as lower slip, even pressure distribution, and lower fuel consumption. Bias tires, on the other hand, wear out faster and are less efficient.
The Right Tire Pressure Is Decisive
Always Measure Tire Pressure When Cold
Tire pressure should only be checked when the tires are cold. Heated tires provide inaccurate readings that deviate from the optimal operating pressure.
Optimal Pressure for Soil Protection & Efficiency
The correct tire pressure ensures maximum contact area, protects the soil, reduces wear, and lowers operating costs. A tire pressure control system helps to optimally adjust the pressure at all times.
