as title, 我的車子最近換上245/40/18的舊胎
才發現避震遇到大幅作動的高低差路面,輪胎會磨到前輪輪弧噴胎膠
有人建議我將前輪拆下換小一點的尺寸來閃
目前考慮225/40/18 or 235/40/18
225胎一定是不會中了,但跟後輪245滾動一圈距離差距2.5%
235胎沒實驗過不知道,滾動距離差距1.24%
我開後驅車,馬力不大,前2度後1度半,原廠避震(故作動行程長)
想請問後驅車這樣搞前後胎不同,對操控上的影響是多少,差距到2.5%會否太大或有危險
(225比235便宜很多XD)
我看比方像BMW的前後配雖然尺寸不同, 但會用扁平比來調整讓輪胎滾動一圈距離接近
猜想應該是有什麼考量
