How to choose a tire for a tractor?

Properly selected tires allow for maximum use of the tire's driving properties and translates into better use of the tractor's power. A correctly selected tire should be in contact with the ground surface with the entire surface of the tread face. Low-profile tires are recommended for large tractors used mainly for transport over even and long distances, while high-profile tires are recommended for small and medium-sized tractors where the characteristics of the crop require the use of narrow tires. Tires are divided into two main groups:

• Radial tires / R / (carcass fibers at right angles to the reinforcement of the tire sides). Tire less resistant to mechanical damage, but more durable and more economical operation of the tractor. An agricultural tire with a larger contact area can work at reduced and increased pressure and compacts the ground less. Allows you to change the tasks of field work of the tractor.
• Diagonal tires /D/ (carcass fibers in relation to the reinforcement of the tire sides at an acute angle). The tire is very resistant to mechanical damage, needs high pressure, compacts the ground more. Agricultural tire designed to work in difficult terrain conditions and with constant air pressure.
