Summer tyre tests in 2021 have highlighted the sometimes dazzling qualities of the best performing tyre products. However, the Allgemeiner Deutscher Automobilclub’s (ADAC) most recent test appears to have been particularly demanding. No tyre received ADAC’s top “very good” rating, and only five models were rated “good” over the two sizes tested – 205/55 R16 V and 225/50 R17 Y. There were some intriguing results at the top of the table. Falken confirmed its increasingly impressive performance of recent years by winning the 17” tyre test with its Azenis FK510 flagship UHP tyre. The Kumho Ecsta PS71 also achieved a “good” rating in the 17” test, while Continental group brand Semperit’s Speed-Life 3 achieved an overall result matching the Conti PremiumContact 6 in the 16” test. There was worse news for the 17” Firestone Roadhawk, which became the only tyre to receive an “inadequate” report.
