“The performance information on the tyre labels is important to choose & compare the right one for your vehicle”
Much like energy labels on various household appliances such as refrigerators and washing machines, Pirelli in Dubai carries a label that relay information of the tyre’s performance, fuel efficiency, wet grip and noise. The same details also appear on websites that deal with online selling of tyres.
The labels or standards are geared towards reduction of fuel consumption by helping drivers make a better and wiser choice when buying new tyres. Although the information on the label is important, it tells a little about overall tyre’s performance and details of particular characteristics are also missing such as;
- Dry road handling and braking
- Wet road aquaplaning and handling
- Riding quality and comfort
- Tyre’s life
It’s always best asking the tyre supplier for a sound advice or perform autonomous tyre tests.
Pirelli in Dubai and many other brands emphasised over rolling resistance of the tyres that accounts for more or less 15 percent of the total fuel consumption. The effect of tyres on fuel costs depends on the purchase and how good you are at taking good care of them;
- Most of the renowned tyre manufacturers produce energy saving tyres in the range. Such wheels are known having a lower rolling resistance and thus offer improved fuel economy without laying much impact on the grip and comfort of the ride.
- For almost every tyre there is, lower pressure is likely an indication of higher fuel consumption and more rolling resistance.
Fuel efficiency (rolling resistance)
Here, labelling represents a tyre’s fuel efficiency over a sliding scale that is from A (best) to G (worst). The variation between best and worst can be as much as 8-percent for cars.
On wet terrain, over-reduction of the rolling resistance heightens braking distance which is totally unsafe therefore, safety maintenance labels also cover wet grip. The wet grip performance is also rated on a scale from A to G that is best to worst respectively. The stopping distance variation between each grade can be one or two car lengths when applying brakes on a speed of 50 miles-per-hour. This difference as indicated by Pirelli Dubai is around 30 percent.
Tyres also lay a certain environmental impact due to the generation of exterior noise. In order to reduce noise pollutions, tyres manufacturers need complying with the stricter maximum noise limits. Whereas, bottom area of the label indicates exterior noise level, measured in decibels (dB) along with a pictogram that represents three “sound bars” indicating relative performance such as;
- A single “sound bar” indicates that a tyre is relatively quiet
- All three “sound bars” represents a noisy tyre
Measuring the fuel economy
When the tyres roll along the road, there’s always a certain degree of resistance to lay an impact on fuel consumption. In simpler words, rolling resistance is the energy consumed by the tyres on the distance travelled. The lower the rolling resistance, better the fuel efficiency and vice versa.
Pirelli in Dubai along with many other tyre brands and countries nowadays pay special attention to labelling for improved performance.
