A part of the tyre that is in contact with the road surface is known as the tread. If a person takes a closer look at the tyres, he/she notices that every tyre has a different tread pattern. Now a question arises- why are they different? The answer to this question is simple. They are different because the unique design of the tread pattern improves the handling and grip of the vehicle, so driving becomes easy in specific climatic conditions. It is easy to identify a tyre by the tracks it leaves on the road due to tread pattern.
There are four parts in a tyre tread
1. Grooves: these can be identified as channels running laterally and circumferential around the tyres.
2. Ribs: it is made up of tread blocks and has a raised section.
3. Sipes: these are tiny slots that are small in size which are moulded into the blocks of the tread.
4. Tread blocks: these are segments that make contact with the road. They appear as raised rubber segments.
We can broadly classify the tyre tread patterns into three categories
Symmetrical tyre tread pattern: one of the most common types of the tyre tread pattern is symmetrical. This type of tread pattern is best suited for passenger car. However, these tread patterns are not for high-performance use. Tyres having symmetrical tread patterns will have independent tread blocks or continuous ribs spreading across the entire face of the tread.
Some key feature of this tread pattern includes
i. It provides high directional stability.
ii. It offers lower rolling resistance.
iii. It offers the drivers a smooth driving experience.
The most flexibility of tyre rotation is provided to the drivers by symmetrical tyre patterns. These patterns also offer excellent fuel efficiency and last for a more extended period. One of the most significant disadvantages of this tyre pattern is that they cannot adapt to changing conditions on the road. Major issue with this tyres will be are overheating, proper grip are not exist, inflation problem on some times, face side crakes and tears, bald problem.
Asymmetrical tyre tread pattern: A tyre that has asymmetric tyre tread pattern comprises of two distinct designs of the tread. One is present on the outer half of the tyre while the other is present at the inner half of the tyre. Both these tread patterns serve distinct functions. The tread patterns at the inner half of the tyre treads ensure protection against aquaplaning and water displacement. The outer half of the tyre treads ensure great lateral stiffness and provide enhanced grip while driving and cornering on a dry surface. The interior noise is also somewhat less. That’s why this tyre are used during summer season due to above same reason and sometime this are also used for heavy duty reason for other vehicles like trucks and cranes.
Some critical features offered by asymmetrical tyre tread pattern are as follows
i. It offers excellent grip during wet climatic conditions
ii. It offers excellent handling experience along with high curve stability.
If you are looking for cheap tyres with an asymmetrical tread pattern, you should visit your nearest tyres shop.
Directional tyre tread pattern: A tyre that has a directional tread pattern is explicitly designed to roll forward in only one direction. In this type of tread pattern, the lateral grooves of the tyres meet in the centre of the tyre tread. The tread patterns resemble the shape of an arrowhead. The main objective of these tread patterns is to restrict aquaplaning while driving at high speeds. The water also gets displaced efficiently through these tread patterns. One of the significant benefits of having a directional tyre tread pattern is that it offers extra traction on the road. This extra traction proves to be very useful in handling mud or snow and this provide extra grip during wet seasons like on rainy and snowy days because sometime noobs drivers are get hesitate to choose symmetrical vs directional tyres and cause huge damage to their life and property so winter tyre or an all-season tyre is expected to have a directional pattern of tread in the tyres.
Some of the key features of the directional tyre tread pattern are as follows:
i. Superior handling on rain, mud and snow.
ii. Excellent protection against aquaplaning or hydroplaning.
iii. Exceptional road handling capacity at high speed.
iv. Excellent grip factor.
An important point to note here is that while replacing or buying new tyres, the tread patterns must not be mixed for attaining the best performance because this help to enhance your driving experience and save from many issue like sock resistance, tread related wear and tear, avoid slipping factor, save from accidental factors and property damage. Health is precious thing for any brands as well as any people.
