Choosing tires for a tractor is important but it is also, for any type of agricultural machinery. Choosing an inappropriate tire can cause a lot of problems and if you buy a used tractor you should not worry much, but if it is a used tractor you may have more problems.
For this, it is important to know the tire codes for agricultural machinery. Knowing what all those numbers and letters mean is important, because there are more letters than in the car.
To understand this, it is vital to explain how the dimensions and shapes of the agricultural tire are. In this way we will understand correctly all the nomenclature. In this image you can see a tire (cut) that allows us to see the main dimensions:
In normal tires, this parameter is usually 100%, that is, the width and height of the ball is the same. In the low profile tires varies between 75% and 85%. On very low profile or extra wide base tires it can even vary up to 60% or 70%. Example: if we have a tire with H = 60% it means that at the height it is 60% of B.
Having said all this, we can now explain how to read a code for an agricultural tire, although there may be several, according to the manufacturer. Everyone agrees to bring first the width of the ball, then the structure (radial or diagonal) and finally the diameter of the rim. Let’s give several examples.
It would read like the previous one, only that from 8 it changes:
Do it yourself, you find a 500 in width in mm, then a 65% ratio of shape (very low profile) and radial structure of 30 inches in diameter. We also find the load index 145 and a maximum speed A5, of 20 km / h. The word tubeless, in English, means that the tire does not have an air chamber.
And with this we hope we have helped you understand correctly the tire codes of the tractors.
