Rolling resistance, noise level and fuel consumption
Tyres are not the only important factor in driving safety. They also affect the noise level produced by the vehicle and with their rolling resistance affect as much as 20% to 30% of total fuel consumption. Therefore, the correct choice of tyres is an extremely important factor in the overall cost of operation of the vehicle. Each tyre carries a standardized label that provides a clear overview of the characteristics and energy efficiency of the tyre.
Fuel consumption
Depending on the rolling resistance of the tyre, its fuel consumption will range from class A (meaning the lowest fuel consumption) all the way to class G (highest fuel consumption). Between classes, fuel consumption increases by about 0.1 liters for every 100 kilometers traveled.
Braking on rain
Critical grip in wet conditions is critical for driving safety. Grades are expressed in performance classes between class A and class G (although D and G are not currently used). In general, the EU designation assumes a speed of 80 km/h. Braking at this speed, the Class A tyre will stop in wet conditions after 28 meters. By comparison, a Class F tyre requires a stopping distance of 46.5 meters, representing a difference greater than 18 meters. From a safety point of view, it makes sense to opt for a higher class tyre.
Noise level
Noise level is the rolling sound produced by a tyre, measured in decibels. The number of filled sound waves on the label is equal to the noise level in the tyres. One sound wave means that the tyre has the lowest noise level, between 67 and 71 dB. The highest level is presented with three sound waves, which is between 72 and 76 dB.
