The German, Austrian and Swiss car clubs ADAC, ÖAMTC and TCS brought the results of a joint test of summer tires. A total of 32 tires in two dimensions passed through it: 205/55 R 16, which is the basis for cars like the Škoda Octavia or VW Golf, and 225/50 R 17, which can also be worn by the Octavia in higher equipment, but also used by the premium Audi A4. .
Car club tests traditionally consist of evaluating the dry and wet behavior of summer tires, but points are also awarded for noise, impact on fuel consumption and wear, ie tire life.
Thus, five criteria are included in the overall evaluation, of which the largest, 40%, weight in wet behavior is important, driving characteristics and braking distances in dry conditions speak twenty percent, and the same applies to endurance, ie wear. Noise and effect on consumption are 10% by weight.
However, the final evaluation is not always determined by a simple weighted average of marks in individual categories, if the tire fails in one of the main criteria (ie in dry and wet behavior), it gets worse than 2.5, this partial mark is written as the overall result. In the case of a sub-mark worse than 4.5, this rule applies to any criterion.
205/55 R 16: The cheaper Semperit breathes on the back of the Continental
The 205/55 R 16 size is a gold standard for new cars, as these are the smallest tires worn by cars such as the Škoda Octavia, VW Golf, Opel Astra or Peugeot 308. Experts gave it three good marks, so three tires are very good. I recommend.

First of all, it is one of the traditional top models, including the Continental PremiumContact 6 produced in Otrokovice, which handled all disciplines evenly, with a slightly worse mark only for higher noise. According to the price comparator Heuréka.cz, however, this model is also one of the most expensive in the test, when its prices start at Czech e-shops at 1580 crowns.

Given the higher price of continents, it may be worth thinking about second place. Semperit Speed-Life 3 tires are also manufactured by a German concern, and although they received a slightly worse rating on the water compared to the PremiůmContact, they are slightly quieter. The resulting stamp is the same and the price is noticeably lower, Semperity can be purchased for 1224 crowns per piece.
The imaginary third place was taken by Bridgestone Turanza T005 tires, which, compared to Semperity and Contintaly, score points in the area of rolling resistance, which is crucial for fuel consumption.
The rest of the tires in this size received a grade of satisfactory, with one exception, which is King Meiler protectors. These “recycled” tires performed poorly in the wet. However, from December last year, the manufacturer should use a new mixture for them.
The ADAC points out that it is very important to take your approach into account when choosing tires in this size. This is because there are big differences between the tires in this respect, so while Nokian WetProof has an estimated life of just 25,000 kilometers, the Goodyear EfficientGrip Performance 2 should be able to cover 55,000 kilometers.
205/50 R 17: one tire completely failed
If one of the cheaper tires was able to match the traditional standard in the form of the Continental in a smaller test, even one surpassed it in the 225/50 R 17 size. PremiumContact 6, despite its perfectly balanced results in wet and dry conditions, took second place.

This time, the first is a tire from the Japanese brand Falken, model Azenis FK510, which is slightly better on dry and wet. One piece costs 2089 crowns and is thus seven hundred crowns cheaper than the other Continental.

The South Korean brand Kumho offers an even more significant opportunity to save money. The Ecsta PS71 model, which can also be purchased for 1897 crowns, took third place. Compared to the competition, however, it has worse driving characteristics, especially in the dry. In the wet, they achieved a slightly worse result of the fourth Bridgestone Turanza T005. However, they still received a mark of 2.5 and that was the last one in this comparison to be rated “good”.
The mark 2.7 on the wet then deprived the most expensive tires in the test, the Michelin Primacy 4, of a better rating. They cost almost 3,000 crowns apiece and excel in the dry, where together with the Pirelli Cinturato P7 C2 tires they achieved the best rating. Traditionally, michelines are also very good in the field of wear, so their high price partly returns in that they last longer.
In the test of 225/50 R 17 s tires, one tire also appeared, which received a rating of “unsuitable”. Firestone Roadhawk disappointed in the wet, during the tests of braking distances he stopped up to two lengths longer than the best Semperit Speed-Life 3 in this respect. The result was a “wet” mark of 4.9, which was then included in the final evaluation.
It is also worth mentioning the tires of the Czech brand Barum belonging to the Continental concern. In the case of size 225/50 R 17, they finished third from the end, their driving characteristics in dry and wet are among the worst and, moreover, they are noisy. They achieved a better result only when measuring rolling resistance.
This year with new labels
From May this year, the tires must be equipped with new so-called energy labels. Compared to the older ones, the number of levels by which rolling resistance, ie fuel consumption, and wet behavior are assessed. Instead of a scale from A to G (from which D was not used anyway), the letters A to E will suffice.

However, I am not tightening the limits themselves, ie the tires that received the best rating A sooner will get it even now, there will be no possibility of super-economical or super-safe tires labeled A + or A ++, as was the case with household appliances. On the contrary, differences in the evaluation of bad tires will be erased, older categories F and G will now fall under the letter E.
The noise rating, which was previously only given in decibels, will also receive a letter rating. Symbols will also be newly marked on the label that the tire meets the standards for grip on snow and ice. So the winter coat can be identified from the sticker.
The last novelty is that there will be a QR code on the labels, after which the customer will get to the public part of the database and will be able to verify the results of the tires and the fact that the label really belongs to them.
In the future, the energy label of tires should also include an assessment of endurance, ie the expected mileage.
