It’s when it comes to renewing your tractor tyres that you are faced with the choice between a discount tyre and a quality tyre.
The price is generally a reflection of the level of quality of the materials used. Choosing a top-of-the-range model will allow you to work with heavy loads and increase your productivity, at very low inflation pressure to preserve your soil for much longer periods, because the tyre will be more resistant to wear. But where does the difference in quality lie?
In this article, we will look at the details and manufacturing techniques which will allow you to choose a top-of-the-range tyre and to understand all the advantages it brings.
The tyre’s basic material is rubber, and it is here that the differences begin between a top-quality and a lessor quality tyre.
Natural rubber (latex) comes from Hevea tree sap and has irreplaceable qualities: it is resistant, elastic, impermeable and reacts excellently to vulcanisation.
It’s the quantity of natural rubber used which will give the tyre is characteristics, such as resistance or elasticity.
Discount tyres tend to be made of synthetic rubber which is much less resistant and durable than the original version.
Companies like Bridgestone have their own plantations in Liberia so as to be able to incorporate a larger share of this pure latex in their tyres and to ensure the ecological and sustainable management of natural rubber.
The quality of a tyre is directly linked to the preparation of the tyre’s basic rubber compound, the manufacture of the rubber being the first step in this process.
The proportion of the elements comprising this rubber compound and the quality of the mixture make it possible to obtain an excellent uniform texture.
This rubber must contain the best ingredients so that it has the properties required by the future tyre: suppleness, grip, performance and resistance.
Research and development make it possible to improve the compounds and materials and to obtain an optimal result: more elasticity, better resistance and in the end tyres that are much more solid and long-lasting.
The role of the research laboratory is crucial, it is at the heart of technological developments involving tyres.
When you choose a Bridgestone brand tyre, the black rubber is not exactly the same as the rubber used by a competitor, within its core is the result of thousands of hours of research to obtain optimal efficiency and durability.
A tyre is not just the result of a rubber compound, it also contains fiberglass, nylon, polyester or cotton reinforcement layers overlapping the rubber.
This stacking of multifibre layers as well as the steel hoops make it possible to structure the tyre and give it its mechanical qualities and suppleness, increasing its resistance so that it can bear heavy loads.
These basic components and reinforcements are now in the form of sheets, they are cut based on the size of the tyre and assembled using a rotating cylinder in a very precise order.
For very large tyres, this operation is usually carried out by hand.
Once this structure has been set in place, it is installed in a tyre curing mould to allow the rubber to transform from a plastic state to an elastic state and to give it its end form.
The curing process will make it possible to bind the molecule chains, it makes the rubber, which is an elastomer, deformable and more solid while preserving all its natural elasticity.
After the manufacturing process, the tyres face numerous automatic control procedures to ensure that the vulcanisation process has been perfectly completed and that all the steps in the operation have been performed smoothly, such as laser trackers to detect any out-of-roundness of the tyre.
For more upmarket productions, an additional human inspection guarantees the superior quality, this allows any minor fault to be detected and perfect products to be placed on the market.
It’s no secret and in general everyone agrees that quality comes at a cost.
In the case of a tool used for professional purposes, this quality will allow you:
