61/100 VANTIQ Index With noticeable compromises

Why 61?

Hinter dem VANTIQ-Index stehen 55 unabhängige Vergleichstests aus elf renommierten Quellen – darunter Automobilclubs, Fachredaktionen und Prüfstellen. Berücksichtigt werden geprüfte Messwerte zu Bremsweg, Kurvenhaftung, Aquaplaning, Verschleiss, Rollwiderstand und Geräusch.

Da Testverfahren und Reifendimensionen variieren, vereinheitlichen wir die Ergebnisse und bewerten sie anhand von elf Kriterien. Die Gewichtung richtet sich nach der Saison, denn an Winter-, Sommer- und Ganzjahresreifen werden unterschiedliche Anforderungen gestellt.

Die Auswertung erfolgt KI-gestützt nach einem festgelegten, einheitlichen Verfahren. Marke, Marge und Lagerbestand haben keinen Einfluss auf das Ergebnis. Jeder Reifen wird nach denselben Regeln beurteilt.
Basis
  • independent comparison tests by motoring clubs, specialist publications and testing bodies
  • verified individual measurements instead of third-party overall scores
  • eleven criteria, weighted differently by season

Missing test results are not invented: tyres without sufficient evidence receive no score.

Price, margin, availability, supplier and brand prestige do not directly affect this score.

Understanding the size

What 255/40 R18 99Y means

The symbols on the sidewall are not a secret code. Select a symbol and the diagram shows the corresponding measurement.

Tread width

The tread width in millimetres. A wider tyre offers more cornering grip, but also more rolling resistance and usually more noise.
