What are the differences in tire tread design?

Tires are designed with different types of tread, each of which is meant for different road conditions and driving styles. There are four different types of tire tread: directional, symmetrical, asymmetrical, and directional/asymmetrical.

Directional (unidirectional)

Directional tire tread features a large V-shaped pattern with large grooves between the tread blocks. The grooves improve hydroplaning resistance at high speeds and are ideal for performance and ultra-high performance applications.


Symmetrical tire tread has the same pattern across the whole tire. This type of tire is the most common and found on most non-high-performance passenger cars because it is typically quiet and long-lasting. Also, they can be rotated in many different ways, which helps to prolong the life of the tires and makes them more versatile.


Asymmetrical tire tread is a bit of hybrid in that it combines a variety of tread patterns for maximum grip on both wet and dry roads that is most commonly found on sports cars. Usually the inside and middle parts of the tire will be designed for wet and/or winter traction, while the outside of the tire will have large tread blocks for maximum cornering capability on dry surfaces.


Directional/asymmetrical tire tread features the V-shaped pattern of the directional tread for discharging water away from the tire and the dry weather traction of the asymmetrical tread. You should follow the same rules as directional tires when it comes to rotation patterns.
