According to new requirements, from November 2012, new tires will be required to have an additional label indicating such key characteristics as rolling resistance, wet grip and external noise. This information should accompany all passenger and truck tires produced after July 2012, and all passenger tires should be marked in the form of markings. In other words, the tires will receive a label translated into a language that everyone understands, from the manufacturer.
According to Goodyear experts, the introduction of a label on tires will change the process of selling and buying. According to it, the buyer will be able to determine the properties of the tire he is buying, and depending on his needs make the right choice in favor of a safer and more environmentally friendly tire. Everything will be quite banal. This is exactly how refrigerators and washing machines are now labeled, based on their appetite for electricity consumption and their ability to withstand leaks. The customer must know what he is buying.

Reliable information has always been valuable. It is important to understand that in relation to tires, such information includes the concept of personal and environmental safety, the value of which is many times higher in comparison with the consumed electricity and flooded floor.
It should be noted that for tire companies, the "costing" of products will cost a pretty penny. The scale of the work to be done is evidenced by these figures: only Goodyear employs more than 270 test drivers, engineers and mechanics to implement the program, they collect information on 10 thousand passenger and truck tires of various sizes. It is good that three indicators of the new marking are included in the list of more than 50 tire characteristics to be evaluated as part of the product testing program. That, at least, is the case at Goodyear.
The report of Emmanuel Robinet, head of Goodyear's tire valuation department, was perhaps one of the most interesting at the seminar.
He very clearly explained what is behind all three parameters.

Rolling resistance
The lower the rolling resistance during tire movement, the less energy is dissipated and, accordingly, the less fuel is required to continue driving. Rolling resistance is up to 20% of the fuel consumption of a car and up to 30% of a truck. Therefore, fuel efficiency helps reduce direct costs and carbon emissions. The difference between the tires of classes G and A in marking is significant. Based on four tires for a passenger car, savings over the period of tire use can be up to 300 euros per tire due to a 7.5% reduction in fuel consumption.
For large trucks with more wheels, the financial difference can be even greater. So, when using class A tires for rolling resistance instead of G tires, a freight company can save more than 5 thousand euros for the period of tire operation.

It is expected that the use of tires with improved rolling resistance, and labeling will simplify the procedure, will reduce carbon dioxide emissions in Europe by 20 million tons per year and save 10 billion euros annually.
Wet tire clutch
Wet grip reflects the tire's ability to stay on the road in wet conditions. Behind this is a reduction in braking distance, improved handling, as well as more confident car behavior.
On the wet grip of a tire, vehicle safety is directly dependent. According to the marking, the braking distance difference between cars on class G and A tires can reach 18 m (on wet roads, for an average passenger car moving at a speed of 80 km / h). This is the length of four cars or one bus or truck, and the border between life and death during emergency braking in an accident passes at a distance of only 1 m …

Noise level
The noise of the tires of a car moving on a surface with ISO characteristics specified by standards is measured by two microphones located at a distance of 7.5 m from the central axis of the car at a height of 1.2 meters. The difference between one black wave and three on the new marking is significant. A bus characterized by three black waves on the marking produces 6 dB less noise than a bus with a single wave (four times noisier). If you multiply this by the approximate number of cars on European roads, the difference will be even more noticeable. Noise may not be heard by motorists themselves, but it still has an impact on the environment. It should be remembered that the overall noise of the car depends on the nature of the road surface.

The human factor, or what the label will not tell
Yes, manufacturers are responsible for the tire characteristics, but how efficiently and fully they will be used depends largely on the owners themselves. In principle, it is enough to monitor two main indicators: tire pressure and tread depth.
At a seminar in Luxembourg, it was emphasized that only tires with the correct pressure can perform their function. Goodyear research shows that both low and high tire pressures affect the behavior of a car on the road and its braking distance. It affects car safety, potential mileage and fuel efficiency. Lower tire pressure than necessary increases rolling resistance, correspondingly increasing fuel consumption and carbon dioxide emissions. To understand this, two cars were installed at the workshop. On a normally inflated wheel and then on a lowered wheel. Pushing the second will be much harder. That's why Goodyear experts, and with them all the tires, advise you to check your tire pressure regularly - at least once a month. In turn, overpressure reduces rolling resistance, but increases the braking distance.

The tread depth is even more important for reducing stopping distances. Tests on a wet surface at a speed of 100 km / h at a training ground in Luxembourg proved that the car on which the new tires are installed stops after 56 meters, then the same car, but with worn tires of the same model (tread depth 1.6 mm) it takes already 114 m to stop completely, i.e. twice as much. Given the potential collision speed, these numbers are even more impressive. By the time the car with the new tires has already stopped, the car with the worn tread continues to move at a speed of more than 70 km / h and it took him more than four seconds to stop completely.

At the seminar, I personally became convinced of this. Frankly, I did not expect that wear so significantly changes the behavior of the tire. And already "bald" tires - just a crime against other participants in the movement and to himself. On the eve of the cold season, comparative rides on slippery, simulating ice surfaces once again confirmed the benefits of winter tires. There, in Luxembourg, the danger of driving summer and winter tires on different axles was undeniably proved. A multi-wheeled car in a bend is unpredictable. And now, sorry for the mentoring tone, I conjure: it is better to ride summer tires in winter than to put winter tires only on driving wheels!
Turns winter without problems
A turnaround takes place in the winter without problems
I hope that someday new labels will not only come to Russia and speak Russian, but also learn to give other valuable recommendations. About the winter ride, for example.

Head of Goodyear Russia LLC Benjamin Willot:
- We organized the Goodyear Safety Days seminar in Luxembourg, because our company places safety at the forefront in its activities. And it doesn’t matter which country we deliver our tires to. The topic of tire safety Goodyear is closely linked to the upcoming appearance of labels on tire products sold in Europe.
Labels relate to three bus parameters: rolling resistance, i.e. economy, noise and braking performance on wet roads.
