The tyre label explained: fuel economy, wet grip and noise
5 min readBy Wheel Fit
The short answer: the label rates fuel efficiency and wet grip from A (best) to E, plus external noise as a decibel figure with a three-bar class. For UK conditions, wet grip is the rating worth paying for.
The three ratings
Fuel efficiency
Really a measure of rolling resistance — how much energy the tyre wastes deforming as it rolls. Lower resistance means marginally better economy, or a little more range in an EV.
The difference between the best and worst classes is real but modest, and it is easily swamped by driving style and by running the correct pressures.
Wet grip
Braking performance on a wet surface. This is the one that matters in Britain. The gap between an A-rated and an E-rated tyre over an emergency stop from motorway speed is measured in car lengths — the difference between stopping short of something and not.
External noise
Shown as a measured decibel value plus a three-bar icon. Note that this is the noise the tyre makes outside the car, for environmental regulation. It correlates loosely with cabin noise but is not the same thing.
Which rating to prioritise
| What you want | Look at |
|---|---|
| Safety in British weather | Wet grip, A or B |
| Fuel economy or EV range | Fuel efficiency, A to C |
| A quieter car | Noise rating, plus independent reviews |
| A sensible all-round buy | Wet grip B or better, fuel efficiency C or better |
What the label does not tell you
This is the important part. The label covers three measurements under controlled conditions. It says nothing about:
- Dry grip and handling — not rated at all.
- Aquaplaning resistance — different from wet braking, and not on the label.
- Tread life — a tyre can score well and wear out quickly.
- Snow and ice — that is the separate snowflake symbol.
- How it behaves worn, which is how it spends most of its life.
This is why two tyres with identical labels can be very different, and why independent group tests are worth reading alongside the label rather than instead of it.
Using it sensibly
Treat the label as a filter, not a verdict. Rule out anything with poor wet grip, then choose within what is left on price, tread life and reviews.
