Another OEM provided the following new-tire rolling resistance
ranges for similar tire categories, which were derived by using the SAE
J2452 test procedure and reported by using the Standard Mean Equivalent
Rolling Force conditions described in the Appendix:
• All-season, 0.005 to 0.0062;
• Touring, 0.0058 to 0.0075;
• Performance, 0.0065 to 0.0083; and
• High performance, 0.009.
* Rolling Resistance Coefficient (RRC) is used for EPA fuel ecomy evaluation, typical RRC number is in the range of 0.005 - 0.013.
* Compared to the coeficient of friction of the performance tire, which is about 1, it is is 100 times bigger than RRC.
* 1980 studies showed that the tire deforming causes 10% change of RRC, like I fucking care.
* a tire can not produce more breaking force than the maximun static friction, unless you are a moron who believed those white dolphin crap.....(恕刪)

(1)式 又說明滾動阻力會消耗最大靜摩擦力 那你還刁車放輪胎氣?...笨也不是這種笨法...
自己都說了 放氣 "運氣好"可以解困..看來你的人生都是靠運氣不講科學的
輪胎氣壓不足就是無法發揮最大靜摩擦力 這種安全常識都沒有 最好不要上路...
還形變阻止滑動哩...草履蟲算了....(恕刪)

你是哪裡來的啊? (2)式 輪胎同時供給最大靜摩擦力跟滾動阻力!!??
完全不知道你在寫啥.....可以肯定絕對不是物理...(恕刪)

哈~ 自己頭腦簡單看不懂還要怪別人:
事實: 滾動阻力 (跑車胎 > 一般胎 > 省油胎) 抓地力 (跑車胎 > 一般胎 > 省油胎)
某人的公式(1) 跑車胎加速還要減掉更大的滾動阻力? 這樣要跑車胎幹嘛?
公式(2) 煞車時煞車力大於最大摩擦力? 火星輪胎喔?!
連自己PO的滾動阻力文在在都是討論[滾阻跟省油]之間的關係 哪來的[加速減速時遇到滾阻]啊?!找出來啊!
有[滾阻]還會有[最大靜摩擦力]嗎?! 還在嫌[摩擦係數不可能大於一]哩~ 難怪會被警察抓..
隨便找個網頁PO就算喔?! 連出處都不知 還亂抄 亂引用 哪個學校哪個系所的哪堂課啊?..引用的模型還是錯的都不知..哈哈哈!!
