1. Just remember one saying 'Low (-er than recommended) tire pressure always is more dangerous than high (-er than recommended) tire pressure." 2. Even on ice, under-inflated tires are not recommended (easily explode due to mild hit). Be careful ambien temperature sudden drop if your car tires are just inflated to recommended value. Make sure even in the coldest moment the PSI is still up to recommended. 3. Give yourself a safety margin---always inflate your car tires + 1 to 5 PSI (or more, depends on weather). 4. Slightly over-inflated provide better "sports" feeling. 5. When there're more than 2 occupants----please "over-inflate" 6.Slightly over-inflated is friendly to your engine and your bank account nowadays. Hence no good for 4-S. • • • • In short: the recommended is the lowest value and you have so many reasons to slightly over-inflate. • • • • • • • • • 1.只要記住一句話:“胎壓低(於推薦值)總是比胎壓高(於推薦值)更危險”。 2.即使在冰上,也不建議充氣不足的輪胎(由於輕度撞擊容易爆炸)。如果您的汽車輪胎剛剛充氣到建議值,請注意環境溫度突然下降。確保即使在最冷的時刻,PSI仍然符合建議值。 3.給自己一個安全裕度---始終為汽車輪胎充氣+1至5 PSI(或更多,取決於天氣)。 4.稍微過度充氣可提供更好的“運動”感覺。 5.人數超過2人時,請“過度充氣” 6. 略為過度充氣對您的引擎和您的銀行帳戶都很友好。因此,對於4-S沒有好處。 • • • • 簡而言之:建議值只是最低值,您有非常非常多原因會需要過度充氣。
