The rolling resistance rating that the tyre corresponds to. The higher this figure, the lower the resistance, the less fuel is spent to overcome it and the more economical the tyre is. Efficiency indices are denoted by letters of the Latin alphabet in descending order of efficiency:
A(highest efficiency),
B,
C,
D,
E,
F,
G(lowest efficiency).
With other things being equal, more economical tyres tend to cost more, but the difference is offset by fuel economy.
The average noise level created by a tyre while driving. The lower this indicator, the more comfortable this model will be, the less additional noise it will create.
Note that EU rules provide 3 categories of tyres in terms of noise.
“Quiet” are considered models with an index of up to 68 dB,
“medium” — 68 – 71 dB,
“loud” — 72 dB and above.
The position that tyre model took in the rating based on test results. The sources of such information are major automotive magazines, car clubs, expert organizations, etc. (see "Rating Source”). Of course, tyres with similar properties are usually compared with each other — for example, winter studded tyres, summer tyres for compact cars (golf class), off-road tyres of a certain size, etc. In our catalogue, you can choose tyres of
Top 3,
Top 5 or
Top 7 different ratings.
Rating info can be very useful given that there are a wide variety of tyres on the market with similar performance. This can mislead even a specialist, not to mention ordinary motorists. And the place in the test allows you to determine the quality of tyres with a certain degree of accuracy without delving into unnecessary subtleties — and the quality is not only “on paper”, according to official info, but also in fact. However, it should be noted that the rating is given for a specific year (usually the year of manufacture of the tyre or the next one after it), and over time, the place of a certain model in the test may change — usually, it shifts down as new, more advanced tyres appear.
