Directional tyres are designed to rotate one way only — improving grip, water dispersal, and driving comfort. In this guide, we explain what directional tyres are, how they differ from asymmetric ones, and how to tell if your tyres are directional so you can make the right choice for your car.
Most drivers are aware of their tyre’s tread, from a depth perspective – that is, they recognise that the tyre tread needs to surpass the minimum limit of 1.6mm in order to be legal and safe to drive on. But what they often don’t realise is that the pattern within that tread plays a part in their vehicle’s performance.
Most car tyres are either directional or asymmetric. And in this article, we’re uncovering what both of these tyre tread types are, so you can decide if your tyres are directional or not.
What Are Asymmetric Car Tyres?
With asymmetric and directional car tyres offering two opposing designs, the best approach is to consider what both look like.
Asymmetric car tyres boast different tread patterns on the inside and outside of the tyre – with each pattern serving a specific purpose based on its location. Typically, the pattern on the inside edge of the tyre dispels and displaces water to limit the risk of aquaplaning, while the pattern on the outside edge of the tyre keeps the vehicle stable when cornering and navigating complex road systems.
Because of this specific design trait in light of the different needs of tyres across different road surfaces and driving conditions, asymmetric tyres are versatile and enhance both performance and safety.
What Are Directional Car Tyres?
Directional tyres have a consistent tread pattern across the entire surface of a tyre, which is built to specifically drive in one direction. That is, tyres cannot be spun or switched around – rather, the tread pattern is uniquely designed to optimise travel when spinning in the correct direction.
It’s worth noting here that there is no particular safety concern if you fit directional tyres in the wrong direction; rather, doing this will simply dull the benefits of the tread pattern. The classic benefits that you might expect to find from directional tyres include reduced road noise, improved stability, and better dispersal of water from in front of the tyre.
How Do I Know if Car Tyres Are Directional?
The easiest way to determine if car tyres are directional or not, is by looking for a specific marking on the tyre sidewall.
If the tyre is a directional design, you will see the words ‘Direction’ or ‘Rotation’ printed on the sidewall, alongside an arrow indicating the correct direction of travel or rotation.
You may also notice a more consistent tread pattern than a tyre which has asymmetrical design, though this is not always the case / the pattern is not always very visible.
