搞壞輪子的最簡單方式 An easy way to ruin your wheels
If you decide to change your own tires, you can safely use soapy water as a lubricant to dismount the old tire and mount the new tire.
如果你想自己換輪胎，你可以用肥皂水當做拆裝輪胎時的潤滑劑。
However, if your rim is made of anything other than chrome plated or stainless steel, I do not advise you to use soapy water.
但如果你的輪框是 鍍鉻 或 不銹鋼 "以外"的材質，不建議你用肥皂水當潤滑劑。
the soap in the soapy water had enough sodium hydroxide (the stuff that makes soap slippery) to corrode the alloy rims
肥皂水裡面的 氫氧化鈉 ，足以腐蝕合金輪框
氫氧化鈉
常用的化學品之一。其應用廣泛，為很多工業過程的必需品：常用於製造木漿紙張、紡織品、肥皂及其他清潔劑等...
氫氧化鈉腐蝕性極高，就連玻璃製品也無法倖免於難...
兩性金屬會與氫氧化鈉反應生成氫氣，英國在1986年有一油罐車誤裝載重量百分率濃度為25%的氫氧化鈉水溶液，氫氧化鈉便與油罐壁上的鋁產生化學變化，導致油罐因內部壓力過載而受損，反應方程式如下所示：
2Al + 2NaOH + 2H2O → 2NaAlO2 + 3H2↑
One optional lubricant is Lemon Pledge furniture polish. Now the dismount and remount job is so easy that even a caveman can do it!
But now the problem with Lemon Pledge furniture polish is that the first time our caveman friend slams on the brakes, the rim will stop, but the motorcycle will act like the Energizer Bunny and keep rolling! Now the tire beads are so slippery that there isn't enough friction between the rim and tire bead to keep the tire from slipping around the rim!
朋友用了檸檬碧麗珠...抓了煞車，輪框是停住了，但是機車還在向前滑！胎唇太滑了，磨擦力不足，結果整個輪胎在輪框上轉
During my 43 years as a motorcycle technician, I've tried everything from Vaseline, axle grease, rear end gear oil, motor oil, soapy water, Crisco, Mazola oil, olive oil, 3-in-1 oil, WD-40, Lionel electric train oil, cod liver oil, castor oil, and candle wax to Vicks Vapo-Rub. All of these products had major drawbacks when it came to tire mounting lubricant and sealant!
在我43年的機車技師生涯中，試過了 凡士林、輪軸承油、齒輪油、機油、肥皂水、人造白油(烘焙用)、玉米油、橄欖油、三合一潤滑油、WD-40、模型火車油、魚肝油、蓖麻子油、蠟燭...傷風膏(薄荷膏)，這些東西拿來當成拆裝輪胎的 潤滑劑/密封劑 ，都各有顯著的缺點。
I finally found a product that will ease the mounting and dismounting of a motorcycle tire. This product also acts as a sealant. The product is known as a protectant. Two brand names of such protectants are STP Son-Of-A Gun and Armor-All Protectant. These products are used exclusively in my shop, and they can be purchased at most auto parts stores and discount store automotive departments.
後來我找到了能夠輕易拆裝機車輪胎的(潤滑劑)產品，同時也有密封劑的作用：
STP Son-Of-A Gun
Armor-All Protectant
If you choose to have your local Honda dealer or certified Honda technician change your tires, I highly recommend that you insist telling your service people,
'PLEASE DO NOT USE SOAPY WATER TO MOUNT MY NEW TIRES.
USE A LUBRICANT THAT IS SAFE AND FREE OF ALKALIS, SUCH AS A PROTECTANT.' "

世界上大致可分為兩類人：
差不多先生 / 隨便小姐
謹慎的人
一個系統，功率是累乘的；誤差是累加的～
有的人，「有這麼嚴重嗎」「幹嘛那麼麻煩」...出狀況時，仰天長嘯「為什麼是我」「偏偏這個時候」...
有的人，總是使用符合規格的零件耗材，定期保養，平穩行車～他的車子，可以預期的，有較大的機率，比較不會顧路。
前者，就是選擇直接在道路上做各種 零件 耗材 的 可行性/耐久 實驗，出了問題，輕則害己，重則殃及他人～
車子上了路，就是有速度，質量又不小的東西，也就是存在著一定的破壞力，
把自己車輛每個環節出錯的可能性盡可能降低，是每個用路人該盡的義務，
意外，就是意料之外
後悔，都是後面才來悔
即便只用一次就乾掉，這個代價，相信遠比意外發生後，車體乃至人身所要付出的，要遠小得多了...

市場上會出現某種專用的產品，意味著其他"堪用"的替代品，都有著或大或小的缺點，這個產品才有生存空間...
使用手冊上會記載某建議事項，意味著其他"也沒事呀"的偷吃步，在人家研發這款車輛的過程中發現，在某些條件下，這麼做是會出問題的...
問問自己：我有像這些 產品/車輛 的研發者那樣，投入那樣多的時數，在鑽研這個東西嗎？
如果沒有：那麼我最好別認為，自己懂得比人家多
小心駛得萬年船...還是謹慎些好...
