上一輪米其林Pilot Preceda2 已經磨的差不多到安全線了
其實這一輪還真不錯,我大概開了4萬了公里,應該算是物盡其用了吧

都已經磨到安全線了,晴天還好,雨天開起來就怕怕的了。
先來了解一下RE001的規格,及這麼標示代表什麼意思吧!

C8H8 是工廠的代號。
CDF2010:表示是第20週 10年份的輪胎。

225/45R17 91 W
225 : 輪胎寬度(mm)
45 : 扁平比(%)
R : 徑向層構造
17 : 內徑(英吋)
91 : 荷重指數
W : 速度表示
輪胎寬度:
這個應該很容易懂,就是指輪胎的寬度。
扁比平:
胎高÷胎寬×100,也就是輪胎的比例、數字愈小,看起來就會覺得比較扁。
徑向層構造:
R (輻射層胎),目前的輪胎大多是這種輻射狀構造
內徑:
荷重指數:
|
|

速度表示:
| Speed Index | L | Q | R | S | H | V | W | Y |
| 最高速度km/h | 120 | 160 | 170 | 180 | 210 | 240 | 270 | 300 |
耐磨系數:
有些輪胎會標示輪胎的耐磨系數,例如:TreadWear 280 (一般也有簡稱 TW
280),意思就是輪胎的耐磨性能為標準輪胎的280%,所以數值越高表示越耐磨,但相對的也會失去一些其它的性能。
輪胎對調:
一般車子因為引擎前置,且驅動輪是在前面,所以前輪的負擔會比較重,因此行駛一段時間之後,應該要進行輸胎對調,以平均輪胎的磨耗,一般每5000公里對調一次即可,不過也有人是每7000公里或10000公里對調。
