Need to buy tires for your car? As the basis for the purchase decision, do you only take into account size and price? Wait … and read this whole article before you buy! Have you noticed the EU tire label that is attached to each tire? This label provides very important information that you must take into account when purchasing.
Find out what the 3 3 sticker information on new tires mean.
The tire label that comes with new tires is something few people care about. In fact, this EU label provides important environmental and safety information for each tire. Such information can help to compare tires for wet grip, fuel efficiency and noise.
This label must be on the tire, since such information is mandatory by law. If you cannot find it on the tire, contact your dealer. We will then analyze each of the fields.
The European label has 3 pieces of information: energy efficiency or consumption (related to rolling resistance), wet grip and noise.
# 1 – Energy efficiency or consumption
Did you know that tires represent up to 20% of your vehicle's fuel consumption? Choosing tires with a high fuel efficiency rating will give you more kilometers in each tank and less CO2 emissions.
Fuel efficiency is rated from A to G on a color-coded scale.
- A (green) = Highest fuel efficiency rating
- G (red) = Lowest fuel efficiency rating
- Classification D is not used for passenger vehicles.
# 2 – Grip on wet roads
Tires with a high wet grip rating will brake more quickly when applying the brakes fully. The EU classification focuses only on one aspect of wet grip – the braking performance on wet tire.
How is wet grip classified?
Wet grip is rated from A to F:
- A = highest rating
- F = lowest rating
Classifications D and G are not used for passenger vehicles.
# 3 – Noise classification
The EU noise rating measures the tire's external noise emissions in decibels.
Since many people are not familiar with the decibel values, an image of a loudspeaker with black waves is displayed to represent the noise level of the tire. The more waves present, the louder the tire.
- 1 black wave: Silent (3 dB or more, below the European limit)
- 2 black waves: Moderate (between the European limit and less than 3 dB)
- 3 black waves: Noisy (above the European limit)
Decibel levels are measured on a logarithmic scale. This means that an increase of just a few decibels represents a big difference in noise levels. In fact, a difference of 3 dB doubles the amount of external noise that the tire produces.
