ADAC Summer tyre test 2023 205/55 R16 good Ranked #19 of 50The Semperit SPEED-LIFE 3 secured the 19th position out of 50 competitors, showing a strong performance in several aspects. The tyre was praised for its excellent performance on wet roads, its efficiency, and its decent tread life. Despite these strengths, it did not display a completely balanced performance, with notable weaknesses on dry surfaces leading to a downgrade in its evaluation, and some concerns regarding its environmental footprint. When it came to driving safety, the tyre delivered satisfactory steering feedback on dry roads but fell short of exceeding a satisfactory rating in handling at the limit, with a tendency to oversteer during sudden evasive maneuvers. However, it managed to achieve a good rating for its braking distance on dry roads. Its performance on wet surfaces was especially commendable, earning good ratings for braking, aquaplaning resistance, and wet handling, thanks to its good grip and safe drivability, thus achieving an overall 'good' rating for wet performance. Despite its positive attributes in terms of projected tread life, wear, and efficiency, the tyre’s noise levels and sustainability assessments prevented it from achieving a good score in environmental impact, narrowly missing out on a higher rating.
