Consultar manual original.Varie selon l'époque et le type de pneu. Consulter le manuel original.因年代和轮胎类型差异较大。请参阅原版说明书或轮胎侧壁标注。 |
💡 Always use the door jamb sticker — not the number on the tyre sidewall. The sidewall shows the maximum pressure the tyre can hold, not the recommended driving pressure. The correct pressure is vehicle-specific, not tyre-specific.
Usar siempre la etiqueta de la puerta — no el número del flanco del neumático. El flanco muestra la presión máxima, no la recomendada para conducir.
Sempre use a etiqueta da porta — não o número no flanco do pneu. O flanco mostra a pressão máxima, não a recomendada para dirigir.
Toujours utiliser l'étiquette de porte — pas le chiffre sur le flanc du pneu. Le flanc indique la pression maximale, pas la pression de conduite recommandée.
始终以车门边框贴纸为准——而非轮胎侧壁上的数字。侧壁标注的是轮胎能承受的最大气压，而非建议行驶气压。正确气压因车而异，而非因胎而定。
