What are the Types of Tire Treads?

Tire Treads:

The tread is that a part of the tire that produces contact with the surface of the road. And if you are taking a glance at different tires on the market, you’ll notice an excellent deal of variety in their tread patterns.

Why are they so different? Because a tread pattern could be a unique design that enhances a vehicle with grip and handling for specific driving conditions. Rather like in an exceedingly novel, you may identify a make of tire by the tracks it leaves on the road.

Every tire tread has four constituent parts:

1. Ribs are the raised section of the tread pattern, made of tread blocks;
2. Grooves are deep channels which run circumferentially and laterally around the tire;
3. Tread blocks are the raised rubber segments that make contact with the road surface;
4. Sipes are small, thin slots molded into the tread blocks.

Taken together, the ribs, grooves, tread blocks, and sipes will be arranged during a unique pattern to modulate the tire’s performance in critical areas like noise, handling, traction, and wear.

And that successively provides tire manufacturers with the flexibility to develop tread patterns to handle specific driving needs like wet braking, dry handling, aquaplaning (hydroplaning) resistance, and traction on ice and snow.

How many tire tread patterns are there? quite a few. But generally, we can distinguish between three categories of the tire tread pattern. Which one does your car have?


The symmetrical tire tread pattern:

The most common style of pattern is symmetrical; it’s suitable for coach tires, but not for high-performance use. Tires with this design have continuous ribs or independent tread blocks across the whole face of the tread, and both halves of the tire feature the identical pattern.

Key features:

1. Smooth driving
2. High directional stability
3. Low rolling resistance

Tires with symmetrical patterns provide the owner of the vehicle with the foremost flexibility for tire rotation without affecting day-to-day performance. They’re also quiet, long-lasting, and fuel-efficient. However, they’re less adaptable to changing conditions on the road. So although symmetrical patterns deliver a gentle grip on a dry road, they will not be as effective in wet conditions as other tires.


The directional tire tread pattern:

A tire with a directional tread pattern is intended to roll forward in one direction only. Its lateral grooves that meet within the middle of the tire tread, resembling the form of an arrowhead. Its purpose is over sporty aesthetic, however. The V-shaped grooves are more capable of resisting aquaplaning (hydroplaning) at high speeds by displacing water more efficiently through the tread pattern.

Another good thing about the directional tread is extra traction, which provides excellent handling on snow or mud. For this reason, a decent all-season or winter tire is very likely to own a directional tread pattern. The additional traction is additionally useful for performance tires on high-performance vehicles.

Key features:

1. High protection against aquaplaning
2. Excellent handling on snow and dirt
3. superb road holding at high speed

The point to recollect about directional patterns, however, is that tire rotation becomes a small amount more complicated. They’ll only be rotated vertically – as an example, from the front of the car to the rear – otherwise, the pattern is going to be oriented within the wrong direction when fitted to a wheel on the opposite side of the vehicle. That will render the advantages of the tire tread useless.

You can keep track of the proper orientation using the arrow indicator printed on the sidewall of the tire. It’s within the same direction because the pattern, pointing within the required direction of travel.


The asymmetric tire tread pattern:

A tire with an asymmetric pattern features two separate tread designs, one on the inner half and another on the outer half the tire. It’s unusual, but both halves serve a definite purpose.

The inner tire tread is accountable for water displacement and protection against aquaplaning (hydroplaning). The outer tire tread has rigid tread blocks for higher lateral stiffness, which provides high grip when cornering and driving on dry surfaces, and quieter interior noise. This mix of features makes asymmetrical tires especially popular to be used on ultra-high-performance cars.


Key features:

1. Excellent handling
2. High curve stability
3. Good grip in wet conditions

However, rather like a directional tire pattern, care must be gaga tire rotation. Vertical rotation between front and back is that the option here. Indicators on the sidewall will guide correct fitting.
