Suitable for
This parameter is indicated for models that are designed for a specific format of operation and differ markedly from conventional tyres for "everyday" use. In our time, there are such destinations:
sports track tyres(namely, semi-slicks and slicks for track days and training on race tracks); off-road tyres - all-
terrain (All-Terrain) and
off-road (Mud-Terrain). Here is a detailed description of each of these options:
— Sports track. A special kind of "high-speed" tyres with a reduced tread depth. More precisely, this feature is characteristic of semi-slicks; in slicks, there is no pattern at all, the surface of such a tyre is completely smooth. This provides excellent speed performance. On the other hand, slicks and semi-slicks are intended mainly for specialized racing tracks with high quality even surfaces; the use of such tyres on ordinary roads is at least not recommended, and for some models it is completely prohibited.
- All-terrain (All-Terrain). Universal all-terrain tyres, designed mainly for dirt roads and off-road, but quite effective on even asphalt. They are inferior to off-road ones (see below) in terms of efficiency on rough terrain, but they behave better on hard surfaces. So it is precisely such rubber that will be the best choice for tech who, in addition to difficult terrain, often have to travel on ordinary roads. Externally, tyres o
...f this purpose are characterized primarily by a rather deep tread and high profile.
- Off-road (Mud-Terrain). Tyres designed for maximum cross-country ability and efficiency on rough terrain, including complete off-road. According to these indicators, such tyres are noticeably superior to all-terrain tyres (see above); outwardly, it is distinguished by a very deep tread and a high profile height (in most models - 60% and above). But for regular driving on asphalt, tyres of this purpose are poorly suited. Therefore, paying attention to off-road tyres makes sense, first of all, to tech who have to drive on dirt roads and off-road most of the time.Fuel efficiency
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.
Wet Grip
An index that determines the overall performance of a tyre on wet pavement. Lettered from
A(highest) to
G(lowest); intermediate options, respectively —
B,
C,
D,
E and
F.
The higher this indicator, the stronger the tyre grips to the wet road, the more efficient and safer it will be in difficult weather conditions. 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 using 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 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.
