Fuel efficiency
The rolling resistance index that the tire corresponds to. The higher this indicator, the lower the resistance, the less fuel is spent on overcoming it and the more economical the tire is. Efficiency indices are designated by letters of the Latin alphabet in order of decreasing efficiency: from A to G (lowest efficiency).
All other things being equal, more economical tires (
A,
B,
C,
D) tend to cost more, but this difference is offset by fuel economy.
Wet grip
An index that determines the overall performance of a tyre on wet pavement. Lettered from A (highest) to G (lowest).
The higher this indicator, the stronger the tyre “clings” to the wet road, the more efficient and safer it will be in bad weather, all other things being equal. At the same time, it is worth noting that a low grip index does not mean unsuitability for driving in rain or snow - you just need to be more careful on such tyres. Conversely, a high index does not relieve the driver of the need to be careful in difficult weather conditions.
Noise level
The average noise level generated by a tyre while driving. The lower this indicator, the more comfortable this model will be, the less additional noise it will create.
