During Lunch hour, I stopped by Kee Hin (aka Michelin to us) to top up the nitrogen gas in my tyres. This would take less and 5 minutes and I would sill be on time back to Work. However, one of the Guys told me that my tyre actually has a puncture.
 |
A normal nitrogen gas top-up revealed a months old puncture.
This meant that during the last top-up where I thought the tyre needed more nitrogen, it was already compromised.
|
 |
We took the tyre for a water test where it revealed a slow leak, as in one small 2mm little silver bubble hanging around outside the leak. The leak happened months ago, which I ignored it until today.
|
 |
The one inch nail was embedded deep inside and it was quite a challenge to pull it out but he did it.
|
 |
At the same time, I can see cracks on my tyres too. I am not too sue when I had them changed but yeah, it's time to change.
|
 |
Normally, to stop the leak, one would push in a piece of rubber strip, twist it around to make an airtight seal and then pull the applicator out. This time, he literally patched the tire but from the inside.
|
 |
Which is a great idea since the air pressure would push against the seal, thereby strengthening it.
|
 |
The whole saga (topping up the nitrogen gas, detecting the leak and sealing it) took less than 15 minutes, no counting small talk and all.
These guys are fast.
