How to choose the right tire tread pattern
To maximize your tires' mileage, it's important to understand the differences between tread patterns: symmetrical, asymmetrical, and directional. Each is designed for a different purpose.

What a tire tread is made of
- Ribs: Raised sections of the tread that run around the center of the tire and provide core traction.
- Blocks: Individual segments spread across the tread surface. They enhance grip, stability, acceleration, and braking performance.
- Grooves: The channels between the ribs that run circumferentially around the tire, helping to evacuate water and maintain tread block flexibility.
- Sipes: Small slits within the tread blocks and ribs that improve traction and water dispersion, especially on wet or slippery roads.
Symmetrical tire tread
The ribs on the symmetrical tread pattern are the same on both sides. Thanks to its large, wide tread blocks, the symmetrical tire pattern provides a smooth ride, minimal noise, good traction, and optimized fuel efficiency.
This pattern is ideal for everyday driving, but not for high-performance applications. Due to their fewer sipes, they perform less well in wet conditions and are less effective at resisting aquaplaning than asymmetric or unidirectional tires.
However, symmetrical tires can be freely interchanged and rotated in any direction, which helps them wear more evenly.

Directional tire tread
These tires are easy to recognize because they have an arrow-shaped tread pattern that indicates the direction of travel. Although directional tires are designed for high-speed driving, they also perform well in wet or dry conditions.
Their tread blocks and sipes are more efficient at wicking away water than those of symmetrical tires. However, directional tires can only be switched from the front to the back; they cannot be switched from one side to the other.
Asymmetrical tire tread
Tires have a distinct pattern on the inner and outer halves of their tread ribs. These tires often feature larger ribs and tread blocks and typically offer improved handling and cornering stability. The shape of the tread blocks and the numerous sipes provide good traction in wet conditions and reduce the likelihood of aquaplaning.
Some tires are similar to directional tires in that they are designed for either the right or left side of the vehicle. However, others can be swapped during rotation as long as the outer sidewall is positioned correctly.
