Agricultural tire 9.50-22 8PR / 9.5x22 / 30 mm tread / FIR

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 properly selected agricultural 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 purposes 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-width tires. Agricultural 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.

What size agricultural tire?

Agricultural tire sizes are usually given in inches (inch; abbreviation or symbol: in or ″) and it is a sequence of numbers and letters denoting the tire width, profile height and construction type, tread type and rim diameter. Agricultural tire 7-14 HR1 is a tire:

• 9.50 - width 9.50 inches,
• 22 - rim diameter,
• R1 - type and type of tread high tread, (R can also mean radial type of tyre).

In addition, information about the number of X PR canvases, speed index, e.g. TT , and the maximum tire load in kg or lbs and the maximum allowable air pressure are provided on the tire.

Dimensions :

• outer diameter: 930 mm (+/- 10 mm),
• inner diameter: 560 mm,
• width: 210 mm (+/- 10 mm),
• number of canvases: FP8,
• load capacity: 1065 kg,
• weight: 28 kg,
• tire size: 9.50-22,

Incorrectly selected tires for the tractor may damage the tyre, the tractor or pose a threat to people and animals and affect the comfort of work and operation, e.g. fuel consumption. Maintaining the correct pressure of agricultural tires allows for the optimal use of the driving properties of the tires, the power of the tractor and extends their life.
