Load index
The load index characterizes the maximum weight under which the tyre can be safely operated. As in the case of the speed rating described above, this indicator cannot be exceeded, otherwise unpleasant consequences are possible, up to accidents. Also note that when selecting according to the load index, it is worth considering the distribution of weight along different axes of the vehicle. And it is worth considering the maximum possible weight when the truck is loaded, in accordance with what to select
truck tyres for heavy loads.
Fuel efficiency
The rolling resistance index to which the tire corresponds. 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 tire on wet asphalt. Identified by letters from
A(highest) to G (lowest).
The higher this indicator, the stronger the tire “clings” to the wet road, the more efficient and safer it will be in bad weather, all other things being equal. It is worth noting that a low clutch index (E, F, G) does not mean that it is unsuitable for driving in rain or snow - you just need to be more careful on such tires. Conversely, a high index (A,
B,
C,
D) 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.
