When you’re planning to purchase tyres for your vehicle, you may be presented with a few choices depicted as symmetrical, directional and asymmetric tyres. If you are reading this article then you probably do not know what these terms mean. Well, do not worry; this article will help you choose the correct tyre for the terrain and season you drive in.
Basically, every one of the three terms refers to the tread pattern of the tyre. The tread pattern of the tyre can be a major factor in how your vehicle performs. Buying a tyre with perfect tread pattern is an art, and this article is your paint box.
The tyre’s tread is the uppermost layer of the tyre, which is in direct contact with the road. On the off chance that you investigate various tyres available, you’ll see a lot of assortment in their tread designs. These numerous tread designs define various key capacities and restrictions of the tyre.
Following are the three types of tread patterns and their key capacities:
- Symmetrical tyre tread
This tread pattern provides high stability, smooth driving, and decreased rolling resistance.
2. Directional tyre tread
This tread pattern provides very reliable safety against the chance of aquaplaning. This tread pattern also prompts a phenomenal grip on muddy terrain, and at high speeds.
3. Asymmetric tyre tread
Asymmetric tread pattern offers; brilliant overall handling, extreme stability, and great hold in wet conditions.
Note: To keep up ideal driving experience and safety, abstain from blending tyre tread designs on your vehicle where conceivable.
Every tyre maker has a unique tread design on each and every tyre, which in fact amplifies the capabilities of the vehicles such as grip and overall handling in explicit driving conditions. If you pay a bit of attention, you could distinguish make of the tyre by its tread design.
In order to completely understand the tyre’s tread, we must dive into its autonomy. Here are founding parts of the tyre’s tread:
Every tyre tread has the following fundamental parts:
The elevated part of the tread is known as ribs and its made up of the tread blocks
The profound channels that run circumferentially and along the side of the tyre are known as grooves
The slender furrows that are slit across the surface of the tread squares are known as sipes. The purpose of sipes is to improve wet traction.
7. Tread squares
The raised part of the rubber on the rib of the tread that comes in direct contact with the ground is known as tread squares
The meet-up point of the tread and sidewall of the tyre is known as shoulder
The fundamental components of the tread such as the ribs, grooves, tread squares, and sipes are be formulated in a unique arrangement to prompt specific balance in the overall performance of the tyre, for example; noise rating, handling, traction, rolling resistance, and wear. Likewise, the tyre manufacturers create tread design in order to address explicit driving needs like dry handling, aquaplaning resistance, traction on snow and ice, wet braking, and fuel economy.
Types of the tread pattern
Following is a detailed overview of three types of tread design:
The symmetrical tread pattern
The most widely recognized and used tread pattern is Symmetrical. The symmetrical tread pattern is reasonable for passenger vehicle tyres, yet not for elite use. Tyres with this pattern have constant ribs or autonomous tread blocks over the whole face of the tyre. In this tread pattern, both halves of the tyre highlight a similar pattern.
Following are the key features of Symmetric tread pattern:
- Elevated directional stability
- Low rolling resistance
- Smooth driving
Tyres with a Symmetrical tread pattern furnishes the vehicle with the most adaptability without compromising the everyday performance of the tyre.
Tyres with Symmetrical tread pattern are additionally tranquil, durable, and eco-friendly. However, they are less versatile to changes that the road might prompt. So, despite the fact that they convey unfaltering hold on a dry road, they won’t be as compelling in wet conditions as other tyres with different tread patterns.
The directional tread pattern
A tyre with a directional tread is intended to rotate in only one direction which is forward. It has parallel grooves on both halves of the tread, which in the end meet in the middle of the tyre’s tread. These grooves basically mimic the shape of an arrowhead.
The motivation behind the directional tread pattern is more than lively stylish, be that as it may. The arrowhead-shaped grooves are progressively fit for opposing aquaplaning at high speeds by efficiently displacing water from underneath the tyre.
The added benefit of tyres with directional tread pattern is the additional traction on the muddy terrain. Consequently, a great all-season or winter tyre is almost certain to have a directional tread design.
The additional footing provided by the directional tread design is likewise suitable for performance tyres on superior vehicles.
Following are the key features of directional tread pattern:
- Increased safety against aquaplaning
- Outstanding handling on mud and snow
- Excellent stability at high speed
Tyres with directional tread pattern can sometimes be very confusing in terms of their installation and orientation. If the orientation of the directional tyre is not correct, the advantages expected of the tyre would not prompt and the tread would be useless. You can ensure the correct orientation of the tyre via an arrow marker imprinted on the sidewall of the tyre. The arrow marker is pointed towards the same direction as the pattern.
Note: tyres with directional tread pattern can only be rotated vertically from the front of the car to the back of the car.
Following are some of the renowned directional tyres:
- BFGoodrich G-Grip
- Dayton D320 EVO
- Kormoran GAMMA B2
- Zeetex HP102
- Zeetex HP102+
- Continental ContiWinterContact TS850
- Dębica Frigo 2
- Goodyear UltraGrip 9
- Nokian WR D3
- Uniroyal MS Plus 77
The asymmetric tread pattern
A tyre that has an asymmetrical tread pattern actually has two patterns, on the inward half and another on outward half of the tyre. Both of the two halves serve a specific purpose.
The inward half of the tread pattern is liable for water dispersal and security against aquaplaning. The outward half of the tread pattern is responsible for high grip, lowering noise levels and overall handling, especially when cornering. This excellent mix of qualities in asymmetric tyres makes it particularly mainstream for use on elite vehicles.
Following are the key features of the asymmetric tread pattern:
- Exceptional handling
- Better curve stability
- Good grip in wet conditions
Much the same as a directional tyre, care must be taken in terms of tyre rotation. Vertical rotation among front and back are the choices here. Pointers on the sidewall will guide the right fitting.
Following are some of the top asymmetric tyres:
- Dunlop SP Sport Bluresponse
- Dunlop SP SportMaxx RT 2
- Goodyear Efficientgrip Performance
- Uniroyal Rainsport 3
- Zeetex ZT1000
- Barum Snovanis 2
- Continental ContiWinterContact TS830 P
- Hankook i*cept evo2 W320
- Nokian WR A3
- Pirelli Sottozero 2
Warning! Do not blend different tyre tread patterns
When purchasing new tyres, abstain from blending various sorts, sizes, or brands of tyre on a solitary vehicle. For best outcomes, source the indistinguishable make and model of the tyre to the ones you as of now have on your wheels, in order to maintain the ideal performance of the tyre.
You can always consult a tire expert online at Pitstoparabaia regarding what type of tire is bes suitable for your vehicle.
When supplanting tyres, it’s important to remember that supplanting a whole set of four tyres is more secure than supplanting only a solitary tyre. The most up to date tyres ought to be fit on the back, and in part worn tyres to the front.
On the off chance that this is beyond the realm of imagination, at that point, drivers are encouraged to guarantee that the substitution tyre has a similar tyre tread design as the other tyre on a similar axel. Blending the tread patterns will hinder the overall performance of the vehicle; it could even be risky and deadly.
