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.
Wear resistance (Treadwear)
Tyre wear resistance rate according to the Treadwear standard issued by the US National Highway Traffic Safety Administration.
This rate indicates how far the tyre is able to travel until the tread reaches a critical level of wear. Treadwear is indicated in conditional points; formally, every 100 points correspond to 48,000 km (30,000 miles). However, it should be noted that testing according to this standard is carried out under perfect conditions — on flat roads, without numerous sharp accelerations and brakings, at a stable temperature, etc. Therefore, real wear resistance, usually, is lower by at least 20 – 30 %; and for a full guarantee, the claimed indicator is generally recommended to be divided by two. For example, formally the value of Treadwear 240 corresponds to a mileage of 48 × 2.4=115.2K km — however, in fact it is hardly worth counting on more than 90K km, and it is best to keep on the value of 55 – 58K km.
Generally, Treadwear ratings up to 250 are considered fairly low, 251 – 300 are considered average, 301 – 350 are above average, and over 350 is typical for
the most durable tyre models. Note that this characteristic is given mainly for summer, less often — all-weather tyres; winter tyres should be quite soft, which makes it difficult to achieve more or less worthy wear resistance rating.
Rating (top list position)
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.
Rating Source
The source where the data of the tyre test results are taken (see "Rating (top list position)"). As such sources, mainly well-known and authoritative publications and organizations are used, however, each user can decide for himself how much he trusts this or that source.
