The tyre label explained: fuel economy, wet grip and noise
8 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.
Snow and ice pictograms
Newer labels can also carry two pictograms: a three-peak mountain snowflake for certified severe-snow performance, and an ice grip icon. These are pass/fail marks rather than graded ratings, and they only appear on tyres that qualify.
Labels of this generation also carry a QR code linking to the product's entry in the official database, which is a useful way to confirm you are being sold what you think you are. See winter, summer or all-season tyres for what the snowflake actually certifies.
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 |
| Winter capability | The snowflake pictogram, not the letter grades |
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.
Comparing like with like
Ratings are only comparable within the same size The label is measured per tyre size. An A wet grip on a 195/65 R15 and an A on a 245/40 R18 are not the same stopping distance — they are each rated against the standard for their own size. Use the label to compare candidate tyres for your car, not to compare cars or sizes.
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.
It is also the one genuinely comparable piece of information you get across tiers, which makes it useful when weighing a budget tyre against a premium one — budget vs premium tyres.
Common questions
- Is an A-rated tyre always better?
- Better at the specific thing that rating measures. An A for fuel efficiency says nothing about wet braking, dry handling or how long it will last.
- Do all tyres have a label?
- New tyres sold for road use carry one. Part-worn tyres do not, which removes your one objective comparison — part-worn tyres.
- Does the noise rating tell me how loud the cabin will be?
- Only loosely. It measures noise emitted outside the car for environmental purposes. Cabin noise depends on the car's insulation too — and matters more on an EV, where there is no engine masking it. See EV tyres.
- Should I choose on label alone?
- No. It covers three measurements and omits dry grip, aquaplaning resistance, tread life and worn performance. Read independent group tests alongside it.
