Easter is tire change time. The summer tire season lasts according to common rule from “O to O”, thus from Easter to October. For many drivers therefore in these days again the new purchase of summer tires is lining up. Every year, therefore, appear around can initially confuse more than help with conflicting results. An exact classification of the test results is more important than ever.

Tire tests are carried out each season by the largest German-speaking automobile clubs ADAC, oAMTC, Austria’s largest automobile club, and the Touring Club Switzerland (TCS) in cooperation. They tested this year in the dimensions 205/55 R16 (test vehicle: VW Golf 7) and 225/50 R17 (Audi A4). These tests are the reference in terms of data abundance and evaluation standard. If a tire scores in one of the “Dry” criteria, “Wet”, “Wear” and “Fuel consumption not the grade “good it is downgraded to the worst individual score. In this way, the ADAC test ensures that “recommendable” Tires deliver a good package in every respect.

The Car picture tested in the dimension 205/55 R16 on a VW Golf 8, the size 215/60 R17 on Jeep Renegade, which is common for compact SUVs, and in the sports car format 265/35 ZR20 on Ford Mustang. Unfortunately, the reader Car picture no comprehensive test table given to the hand. Three resp. two inconsistent criteria with school grades (16-inchers: “Wet,Dry, Cost”, SUV: “Off-road, wet, dry”, Sport tires: “Wet, dry”) steam up the elaborate test to a comparatively undifferentiated distillate. Results that deviate from the ADAC test are unfortunately not comprehensible. However also Car picture with a devaluation scale, the tires starting from a single mark “3” devalued in a safety-relevant criterion. Unfortunately, however, these individual criteria are just not shown anywhere.

Test car with front-wheel drive

The Society for technical supervision (GTu) tested the dimension 225/45 R17 in cooperation with the European Automobile Club ACE and the second largest Austrian traffic club ARBo (Auto-, Motor- und Radfahrerbund osterreich). This dimension is common both in models of the compact class (VW platform MQB, Peugeot 308, BMW 1 Series, Mercedes A- and B-Class) and in the middle class (A4, BMW 3 Series, Mercedes C-Class). Test vehicle was the Golf 8. GTu and ACE provide a table with detailed individual criteria, but not quite as profound as ADAC, oAMTC and TCS. In addition the GTu weights traditionally the price so strongly that under circumstances the technically best tire does not become overall winner.

GTu table requires profound evaluation

The criterion “technical characteristics” is of decisive importance in the GTu test. It is recommended to compare individual criteria on the basis of the table and, in the case of unexpected results such as the test winner Nexen N’Fera, to use the ADAC/oAMTC table in the, albeit not quite identical, dimension 225/50 R17 as a cross-check. Furthermore, interesting additional information can be found in the text.

ADAC, oAMTC and TCS measuring consumption on the circuit in the Audi A4.

Thus the Taiwanese tire Maxxis Premitra 5 classified in the final result as “very recommendable” is at the same time the tire with the longest braking distances in the test. With the worse rated Michelin Premacy 4, the Golf stands 8.6 m earlier in the wet from 100 km/h. Although the Maxxis wins the aquaplaning rating by a wide margin, that is, it can be kept precisely on the road for the longest time in the rain. Nevertheless, we would not go for the tire with the longest braking distances.

All-rounder from Continental

In general, the same treads in different formats may well show different properties. Some tires are ideal specifically for a certain format. But there are also tires on, which in the overall view of all tests in all formats consistently belonged to the best. The Continental PremiumContact 6 is one of these winners.

In the dimension 205/55 R16 the Continental PremiumContact 6 is test winner with the ADAC and second with the Car Image. In the format 225/50 R17 the Continental becomes with the large ADAC test second. Especially the performance on wet conditions is emphasized in all tests. But even on dry roads, the Continental is consistently one of the best tires. In the GTu test, the PremiumContact even achieved the shortest braking distance (from 100 km/h) of 34.5 m on dry roads.

The Korean tire Kumho Ecsta HS51 attest the testers of Car picture and the automobile clubs also excellent wet properties. In the Car picture it becomes in the dimension 205/55 R16 even test winner. However, the ADAC and its partners rate the Kumho because of weaknesses in dry handling on the overall mark “satisfactory” from. The GTu does not test the Kumho.

Even the Bridgestone Turanza T005 was not tested by the GTu. In all other tests in the formats 205/55 R16 and 225/50 R17 it belongs however at least to the top four of the test field. Quite different from the Kumho, the Bridgestone clearly has its parade discipline on dry roads, where it provides the front-wheel drive models from the VW Group with sporty, precise handling and short braking distances. On wet it belongs to the good, if not very good tires.

Durable tires from Michelin and Goodyear

In front is also always the Michelin Primacy 4, but leaves an uneven picture. In the GTu (225/45 R17), it achieves the shortest wet braking distance at 48 m. In the big test of ADAC, oAMTC and TCS (225/50 R17) the Michelin is best in dry conditions. But it is downgraded to “satisfactory” because of weaknesses in aquaplaning. In the size 205/55 R16 falls the Car picture On the other hand, it has imprecise handling on dry roads.
