Complete Information On Tyre Construction, Types And Tread Patterns.


When given a brochure to select a car of our choice, we get carried away by its aesthetics and appearance. We fail to consider the type of tyre the car has, which happens to be a crucial component of a car. Filtering the right tread pattern is vital as tires are the only source of contact between the surface and the vehicle. The choice of your tyre tread has a huge impact on handling the vehicle and the properties of the tyre.

Benefits Of Having A Right Tread Pattern:

Having a suitable tyre tread will increase the traction between the vehicle’s tyre and surface. This reduces the chance of unwanted wears on the tyre. As a result, the tyre lasts longer than its expected life. Also, the vehicle’s steering capability majorly depends on the tyre tread. The benefits of having a suitable tread pattern influence efficient fuel consumption, decreased tyre noise, and enhancing ease of driving.

Driving Factors In Choosing A Tyre Tread:

The vital features in a tyre tread include its pattern, construction and tread types. Having a close study of these factors will help you understand the essence of the specific model of tyre.

Features Of Tyre Tread:

Sipes: Passageways in tyre lugs, narrow voids of size (width) 0.3mm-1.5mm, are called the sipes. The purpose of the sipes is to channel the water from the tires underneath in snowy and wet conditions. Also, against aquaplaning, resistance is created.

Tread Lugs: The tread lugs help in providing good traction to the wheels. Desired features and components are added as well as carved in the tread lugs.

Tread Rib: The circumferential ribs which encircle the tread of the tyre is called the tread rib. They are also called the ‘Transverse voids’.

Tread Groove: The grooves are very similar to that of the sipes, except that they are much longer and deeper. The specific size, pattern and pattern of the groove enhances the quality of the tyre. The grooves improvise the ability of the braking system and the control of the steering. In addition, they affect the noise level caused by rolling.

Dimples: Dimples aid in improving the tyre cooling ability.

Tread Voids: The tread voids indulge in the duty of channelling the water in the tyre. The water is eliminated through the wide tread voids with is present alongside the axis.

A combined effect of the tread voids and the tread lugs help enhance the traction on the wet surfaces. At the same time, they aren’t safe to be used on dry surfaces. The tread voids in a tyre solely depend upon the purpose for which the tyre is used.

Tread Patterns: Below, you will be able to get an idea about the fundamental tread patterns in a tyre. Calibration of the tread elements results in forming a suitable tyre. A tyre had two distinguished parameters, namely, winter tyres and summer tyres.

Rib Patterns: They are parallel voids in S-shape. They are found alongside the axis. They help in lowering the rolling resistance. They enhance the driving experience by providing high directional stability and notable steering control. They aid in maintaining high speeds. But they provide poor grip on the wet roads. Also, the flexing of treads and the stress created thereby is likely to result in tyre cracking. They are fitted in the front wheels or rear wheels and are suitable in drivetrains, concrete and tarmac.

Lug Shape: Pattern refers to grooves that are positioned perpendicular to the circumference of the tyre. They help in improving the traction and has excellent grip while braking as well as while accelerating. However, they produce noise at high speeds. Due to additional rolling resistance, they are not comfortable for any high-speed travel. These tyres are designed to suit dirt roads. They are often seen in the rear wheels of buses, trucks and terrain vehicle.

Mixed Rib & Lug shape: The pattern is a combination of the two previous shapes. It features a varying combination of the S-shaped voids alongside the axis and in the perpendicular grooves. The central rib offers good control over the direction, and the lugs enhance the braking and driving power. The shape offers balanced performance, and thus, they are not good in areas like the more specialized designs. However, these tyres go well in paved as well as dirt roads.

Block Shape: Patterns here pertain to all designs with independent blocks. They are found alongside the tread and are separated by interconnected grooves. It provides good steering as well as stability in wet and snowy roads. They also have efficient water dispersing properties in them because of the grooves. It provides low durability based on the size of the treads. The pros include their efficacy on snowy roads.

Asymmetric Shaped Pattern: Pattern differs on either side. Bigger blocks are found on the outside. The internal blocks appear to be small, with grooves dispersing water outwards. The larger contact area help in high-speed travel. They have tread wears in the tyre’s outside. The bigger blocks help in improved stability while turning. They had to be positioned properly due to the side dissimilarities. These tyres are suitable for all kind of sporting vehicles and vehicle with more aggressive driving.

Directional Pattern: They have lateral grooves on the tire’s either side. They are placed at the same angle. The benefits include high traction and braking system, channelizing water underneath the tyres and enhancing high-speed driving. Since they are directional, the tyres have to be of correct orientation when being installed. Directional tyres are profoundly seen in passenger performance vehicles.

The intricate tread patterns found in a 4×4 tyres Wokingham has a huge purpose behind them. Once we understand how the different tread patterns affect the tyre’s performance, we’d be ready to choose the best set of tyres for our vehicle.
