What is the difference between asymmetric and directional tyres?
Asymmetric and directional tyres compared
These are the two main tread pattern designs used on modern car tyres. Each has a specific fitting requirement and offers different performance benefits.
Asymmetric tyres
Asymmetric tyres have a different tread pattern on the inner and outer edges of the tyre. The outer edge is optimised for dry grip and cornering stability, while the inner edge is designed for water dispersal and wet traction. They must be fitted with the correct side facing outward, which is marked OUTSIDE on the sidewall. They can be rotated to any wheel position on the car.
Directional tyres
Directional tyres have a V-shaped or arrow-shaped tread pattern designed to channel water away from the contact patch as efficiently as possible. They must be fitted so the tread pattern points in the direction of rotation, which is marked with an arrow on the sidewall. They can only be rotated front to back on the same side of the car, not swapped left to right.

Both types are safe and effective for everyday driving. The choice depends on your priorities and what is available in your tyre size. Your fitting centre will ensure they are mounted in the correct orientation.
