失壓續跑胎RFT使用心得

失壓續跑胎是BMW的一個新重點,普遍用於多款車上,在1.3以及至少新X5上都已經採用。

失壓續跑胎會有RSC記號。

失壓續跑能耐其實是可變的,續跑距離從五十到二百五十公里,時速不可以超過八十。
失壓續跑胎RFT使用心得
原廠說要用有BMW標記的,真的有嗎?眼花沒仔細找。
,使用一陣子後,心得為:
1.省下備胎空間。
2.很多爭議,很多BIMMER一拿到車就換掉,或在換胎時不再續用,對於此,我唯一的疑問是,既無備胎空間,又換成一般胎,破胎時豈不悽慘?如何處理?他們都另外買備胎丟行李箱嗎?不曉得。
3.運動設定款可以用,但可能是胎壁厚實關係,真的癲頗反應較為明顯。
4.單價很高。
雖然毀譽參半,但對於我這種有爆胎換胎恐懼症的人,我還是很欣賞這種產品。我所配的是馬牌,大家參考。

1.準備一組補胎劑,BMW原廠有賣,各大汽車賣場也有賣(打氣機配合千斤頂使用)
2.太嚴重也只能打電話找汽車救援了
因為我也被路上陷阱暗算過三次....防爆胎真的很好用...
不會耽誤原定行程,有空再開去補胎即可....
所以我還是捨性能胎繼續用又貴(單價約6500)又重又顛的防爆胎
我是準備一台小型電動打氣機在後車箱
希望永遠不要有用到的一天
電動打氣機這東東就我知道是沒多大用的喔,因為一般他的POWER都不夠,我還看過一家四口壓在車上,電動打氣機在那喘氣,車主一臉疑惑看著,臉上似乎寫著"怎都還是平的"的有趣景象呢。另外就是如果已經破胎,這東東如何有作用?
我的是Bridgestone RE050 RFT
真的很硬...不過抓地性還不錯



誰可以告知這些意思?

所以要先灌補胎劑,填補破洞後,用千斤頂把車頂起來打氣,
光車子本身重量負荷就造成氣不好打了
他一家四口都坐車上當然沒用阿

車子本身的負重? 他為什麼不把輪胎取下來後再來補胎打氣呢?

抱歉 補胎劑 與 電動打氣機 這兩種東西我都沒親自用過

純粹好奇
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course to 6,000 miles(9600Km). For example, a tire graded 150 would wear one and a half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics.

TRACTION AA, A, B, C
The traction grades from highest to lowest, are AA (the highest) A, B, and C and they represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C will have the lowest traction performance.

WARNING: THE TRACTION GRADE ASSIGNED IS BASED ON A WET BRAKING (STRAIGHT AHEAD) TRACTION TEST AND DOES NOT INCLUDE CORNERING (TURNING) TRACTION.
TEMPERATURE A, B, C
The temperature grades are A, B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades A and B represent higher levels of performance on the laboratory test wheel than the minimum required by law.

WARNING: THE TEMPERATURE GRADE IS ESTABLISHED FOR A TIRE THAT IS PROPERLY INFLATED AND NOT OVERLOADED. EXCESSIVE SPEED, UNDER INFLATION, OR EXCESSIVE LOADING, EITHER SEPARATELY OR IN COMBINATION, CAN CAUSE HEAT BUILDUP AND POSSIBLE TIRE FAILURE.

約略懂它的意思了,但"TREADWEAR"翻成中文應該是什麼呢?這胎的TREADWEAR 是 280。其他二欄都是A。
