For this year’s summer tyre test, German motoring organisation ADAC, together with its Austrian and Swiss partners, evaluated a total of 31 tyre models – 16 size 195/65 R15 91V tyres were fitted to a VW Golf for testing, while 15 size 215/65 R16 98H products were evaluated using a VW Tiguan. Most tests were performed by ADAC personnel at facilities owned by Bridgestone and Continental.

While no products received the top ‘very good’ rating, almost a quarter of the candidate tyres received a rating of ‘good’ and the majority were considered ‘satisfactory’. Two ended testing with an ‘adequate’ rating, while one was ‘unsatisfactory’.

First place in the 195/65 R15 91V group was occupied by the Pirelli Cinturato P1 Verde, the tyre withdrawn from the results table last year due to significant variations between individual tested tyres. The Pirelli tyre received a rating of ‘good’ along with four other products, the Bridgestone Turanza T001, Conti PremiumContact 5, Goodyear EfficientGrip Performance and Esa-Tecar Spirit 5 HP. None of these five tyres were found to have any significant weakness. The Continental tyre topped the wet testing category, and the ADAC testers considered the affordably-priced Spirit 5 HP “surprisingly good.”

In contrast to the five highly-rated tyres, the large group of ‘satisfactory’ tyres that followed were all deemed to have at least one weakness worth drawing attention to. This group was headed by the Dunlop Sport BluResponse, which finished in sixth place, followed by the Nokian Line (previously xLine), Vredestein Sportrac 5, Aeolus PrecisionAce 2, Kumho Ecowing ES01 KH27, Michelin Energy Saver+, Sava Intensa HP, Semperit Comfort Life 2, Hankook Ventus Prime³ and the Maxxis Premitra HP5. The Dunlop, Nokian, Vredestein, Michelin, Sava, Semperit and Hankook tyres missed out on a better rating due to being marked down in the wet disciplines, while wear was an issue for the Kumho and, even more so, Maxxis tyres. According to the ADAC, the last-placed GT Radial Champiro FE1 only received a rating of ‘adequate’ primarily due to its “weakness on wet road surfaces.”

Amongst the tested size 215/65 R16 98H SUV tyres, only two models – the Goodyear EfficientGrip SUV and Cooper Zeon 4XS Sport received a ‘good’ rating. The Goodyear tyre received the highest score in the wet disciplines and was also deemed to have delivered good performance in the dry, as well as in the wear and fuel consumption tests. The Zeon 4XS was also considered a well-balanced product that performed well in the wet and the dry, however its wear characteristics prevented it from gaining an even higher rating.

As was the case with the smaller tyre size, the SUV test included numerous products that received a ‘satisfactory’ rating: The Firestone Destination HP gained third place in the test and was followed by the Nokian Line SUV, Pirelli Scorpion Verde, Semperit Comfort Life 2 SUV, Uniroyal RainExpert 3 SUV, Barum Bravuris 4×4, General Tire Grabber GT, Apollo Apterra H/P, Hankook Dynapro HP2, BFGoodrich g-Grip SUV and Bridgestone Dueler H/P Sport. Below this group, entitled to just an ‘adequate’ rating, was the Michelin Latitude Tour HP, which the testers said showed “particular lateral control weakness in the wet.” The wooden spoon in this test, however, went to the Yokohama Geolandar SUV, which was rated ‘unsatisfactory’ and was said to have “completely failed” when it came to the wet braking discipline.

It’s worth noting that Michelin, which recently launched its “Long-Lasting Performance” strategy, was rated top of the class for wear in both tests. Another comment from the ADAC testers, something they considered “irritating,” was that the presence of a M+S marking on the sidewall of some of the SUV summer tyres they evaluated – these products being those from Barum, General Tire, Goodyear, Hankook, Michelin and Yokohama. According to the ADAC, the marking’s presence gives “the impression that these summer tyres aren’t just all-terrain, but also particularly suitable for winter use.” In reality, the rubber compounds in these tyres lose elasticity at low temperatures and thus suitability for slush and snow. “Anyone choosing to do without a genuine SUV winter tyre in order to save money must accept a significant decrease in safety,” warns Dr Reinhard Kolke, head of the ADAC Technical Center.
