How can I tell if my tyres are directional?
Check the sidewall for a rotation arrow or “ROTATION →” marking. Directional tyres must spin in that direction to perform properly. :contentReference[oaicite:9]{index=9}

Tyre tread patterns explained: symmetrical vs asymmetrical vs directional
Tyre tread patterns explained: symmetrical vs asymmetrical vs directional
The tread pattern of a car tyre affects grip, braking, handling and noise. Tyre makers design different patterns for different conditions – from dry-road stability to wet-weather braking and winter traction.
In this guide we explain the three main tyre tread patterns, how to identify them on your own tyres, and what each type is best for.
Quick summary (TL;DR)
- Symmetrical tyres are common, quiet and good for everyday driving.
- Asymmetrical tyres balance wet grip and dry cornering – but must be fitted the right way round.
- Directional tyres are designed to rotate one way for great wet performance – and have stricter rotation rules.
The different tyre tread patterns
Most road tyres use one of these three tread designs:
- Symmetrical
- Asymmetrical
- Directional
How to identify your tread pattern
You can usually tell what tread type you have by the pattern itself and the sidewall markings:
- Symmetrical: the tread looks the same across the tyre and there are no “inside/outside” labels or rotation arrows.
- Asymmetrical: the sidewall is marked “INSIDE” and “OUTSIDE”. The inner tread has more grooves for wet grip, while the outer shoulder has larger blocks for cornering. :contentReference[oaicite:1]{index=1}
- Directional: the sidewall shows a rotation arrow or “ROTATION →” marking. The tread often forms a V/chevron shape to clear water efficiently. :contentReference[oaicite:2]{index=2}
- Directional + asymmetrical (hybrid): some tyres have both an arrow and inside/outside labels, so they must follow both rules. :contentReference[oaicite:3]{index=3}
Symmetrical tyres
Symmetrical tyres have the same tread layout on both sides of the tyre. This makes them the most common choice for small to medium cars and everyday driving.
They tend to be durable, quiet and can reduce rolling resistance – which helps fuel economy.
Asymmetrical tyres
Asymmetrical tyres use two tread designs in one, with different inner and outer zones. The inner side typically has more grooves to improve wet grip and reduce aquaplaning, while the outer shoulder is stiffer for stability and dry-road cornering. :contentReference[oaicite:4]{index=4}
They can be fitted on either side of the vehicle, but they must be mounted with the correct “inside/outside” orientation. Fitting them the wrong way round reduces performance and safety. :contentReference[oaicite:5]{index=5}
An example of an asymmetrical tread pattern can be found on the Michelin Primacy 4:
Directional tyres
Directional tyres are designed to roll in one direction only. The tread usually forms a V or arrow pattern that channels water away from the contact patch, giving strong wet-road performance and resistance to aquaplaning. :contentReference[oaicite:6]{index=6}
Because of this, they must be fitted to a specific side of the car. If a directional tyre is mounted backwards, wet grip and braking performance drop significantly.
This design can limit rotation options, but it’s one reason directional tyres are popular on performance cars and all-season wet-focused tyres.
An example of a directional tread pattern can be found on the Michelin CrossClimate 2:
Comparison: which tread pattern is best?
| Tread pattern | Best for | Main benefits | Things to know |
|---|---|---|---|
| Symmetrical | Everyday driving | Quiet, durable, often lower rolling resistance | Less sharp handling than other types |
| Asymmetrical | Mixed UK wet/dry conditions | Wet grip inside, dry stability outside | Must be mounted “inside/outside” correctly |
| Directional | Wet weather, performance | Excellent water evacuation and wet control | Must follow rotation arrow direction |
Fitting and rotation rules
Correct fitting matters for safety and tyre life:
- Symmetrical tyres: can be fitted either way round and rotated to any corner.
- Asymmetrical tyres: can be swapped left/right, but only if they keep the correct inside/outside orientation.
- Directional tyres: can usually be rotated front-to-back on the same side only, unless they’re removed from the rim and remounted. :contentReference[oaicite:7]{index=7}
Can you mix tread patterns?
It’s best to fit the same tread pattern on each axle. Mixing patterns can lead to uneven handling, braking differences and faster wear. If you’re replacing just two tyres, match the tread type already fitted on that axle where possible. :contentReference[oaicite:8]{index=8}
Choosing new tyres
Buying new tyres doesn’t need to be confusing. Start by checking what’s currently fitted – the tyre size and model are shown on the sidewall.
If you’re happy with your current tyres, you can replace like-for-like. If you want to improve comfort, noise, wet braking or fuel economy, comparing tread type and performance reviews is a good place to start.

Tyre tread pattern FAQs
What does “inside / outside” mean on tyres?
That marking means the tyre is asymmetrical. The “outside” face must point outward when fitted to deliver the correct wet and dry performance. :contentReference[oaicite:10]{index=10}
Can I rotate directional tyres?
Yes, but usually only front-to-back on the same side of the car unless the tyres are remounted on the rims. :contentReference[oaicite:11]{index=11}
Are asymmetrical tyres better in the wet?
They’re designed to balance wet grip (inner tread) and dry cornering (outer shoulder), making them a strong all-round choice for UK roads. :contentReference[oaicite:12]{index=12}
Can I mix different tread patterns?
It’s safest to avoid mixing patterns on the same axle. If you replace two tyres, match the tread type already fitted on that axle where possible. :contentReference[oaicite:13]{index=13}
