There are several types of tires that are used nowadays for the various types of farm tractors, lawn tractors and other automobiles and these are low, extra low and high pressure tires. Their use depends not solely on the inflation pressure, but on a few other factors, such as tread contact area with the ground and the diameter of the wheel.
High Pressure Tires
A while ago, the high pressure tires were used for both trucks and cars. However, as it turned out that this type of tires were not shock absorbent and since the comfort is one of the most important thing concerning cars, these were switched to low pressure tires, while the high pressure ones continued to be used only with trucks.
Low Pressure Tires
As mentioned above, the low pressure tires are used in small automobiles and cars due to their shock absorbent properties.
Extra Low Pressure Tires
Also nicknamed ‘balloon tires’, this type of tires comes very in handy with large and heavy machines and tractors, but also for racing cars, as they are larger in width and don’t slip easily in sharp turns. They are also recommended for sandy surfaces.
Background
In the past, tires used for tractors were very heavy and allowed running at reduced speeds, as they had some iron wheels. Moreover, they were causing a lot of noise. The chassis frame and the driver of the tractor were the ones to manage the road shocks.
As time passed and technology evolved, pneumatic wheels came to replace the iron wheel tires. Pneumatic wheels also referred to simply as tyres, have two pieces combined and fitted on the machine rims: the tires and tubes. The tubes are inflatable and these carry the entire weight of the tractor, while the tire resembles a rubber bag covering the tube.
Tractor Tires Features
These are very popular elements used for tractors especially in the world regions which have well developed agricultural sectors. The United States, New Zealand, India, Canada, United Kingdom, Australia and other countries are to be found on such a list.
To summarize a bit, the main functions of the various types of tractor tires are: carrying the weight of the machines, decreasing the vibrations transmitted to the machine while functioning, absorbing road shocks, providing higher grip on ground surfaces. The grip is better when the correct tire type is used for a particular soil surface, be it sandy, smooth, bumpy, etc.
