車呔前後厚度問題?
我想問如果後車呔跟前車呔厚度唔一樣可以嗎?會否有影響?後車呔厚過前車呔可以嗎?215/45/R17前,215/50/R17後?
最佳解答:
其實好多高性能後驅車嘅車呔, 前後嘅厚度比例都唔一樣嘅, 就好似BMW M6咁, 就用255/40-19, 後面用285/35-19. 而M3咁, 前245/40-18, 後面用265/40-18, 就後面係厚過前面 (245 x 40% < 265 X 40%) 不過你個case, 前後呔闊度一樣, 但後面厚過前面就特殊D. 要睇番你原廠呔嘅size係咩. 盡量保持+/- 唔好超過2.5%. 當你原廠係215/45-17, 直徑即係 21.5 x 45% x 2 + 17 x 2.54 = 19.35 + 43.18 = 62.53 cm; 215/50-17 = 21.5 x 50% x 2 + 17 x 2.54 = 21.5 + 43.18 = 64.68 cm. 比原裝多3.4%. 即係你揸車時, 表版話你行緊100km/h, 其實你係行緊103.4 km/h.
其他解答:
It should be ok, since everyone's driving is different. the level of wearout on each tire is different too. The biggest difference probably is depends on if your car is FF or FR.
