ADAC Summer tyre test 2023 205/55 R16 good Ranked #7 of 50Securing a respectable 7th place out of 50 contestants, the Continental UltraContact demonstrated a well-rounded performance with its strength particularly noted on dry roads and its environmental credentials. It garnered praise for its balanced driving experience, superior performance on dry surfaces, and impressive environmental footprint, boasting an exceedingly high mileage potential. However, it was not without its flaws; the tire experienced slight weaknesses on wet surfaces, with its performance in aquaplaning situations falling short of expectations. Despite these challenges, its short braking distance on dry roads helped it achieve an overall 'Good' rating. Although its handling and grip in wet conditions were commendable, its inability to efficiently combat aquaplaning slightly marred its performance. Nonetheless, its outstanding projected mileage and minimal environmental impact - highlighted by its low weight and reduced fuel consumption - solidified its reputation as a commendable choice for those prioritizing sustainability alongside performance.
