After ~5000 miles of commuting to and from work, I had my first flat today.
I know I should consider myself lucky to have it that late, but it's tough to feel lucky while looking at a tire desperately empty.
Where I do consider myself lucky is that it happened 50 yards from my office so I just pushed the bike there, parked it, removed the wheel and did the repair in my office.
Still, this is my first ever, so would you mind reviewing my process of repair? here is what I did:
1) used a couple of plastic tyre-levers to remove the tyre on one side
2) removed the tube (and was extra careful while removing the valve)
3) checked the inner side of the tire for remaining debris that might have caused the flat on the first place
4) inflated the tube to identify the leak (at that point I realized the even though it was leaking, the tube was holding its air quite well, obviously not enough to ride on it but it deflating completely would be a matter of minutes... This just seems to indicate the hole was not that big)
5) marked the leak with a marker
6) emptied the tube so that the patch would not be pressured while being attached
7) roughened the surface a bit with the piece of rough thing provided with the patches (both the tube and the tire were dry during the whole process, so no need to wipe any water...)
8) applied the patch (was a glueless one - only ones I had on me) with the hole right in the middle of it
9) pressed it quite strongly and let it dry for 5 minutes (the instructions were saying 1 minute)
10) put the tube back in the tire
11) put the one-side-of-the-tire-that-was-out back on the rim
12) checked for pinches and that the valve was straight
13) inflated as much as I could: my usual pressure is 8 bar in my 28mm tires, I inflated until arms were aching (pump guarantees 11 bar, turned out I stopped at 5)
14) left the wheel in my office till noon to keep an eye on it that it keeps its pressure
15) installed it back on the bike
At the end of the day I rode my 10 miles home on it. And it held!
I checked the pressure and topped it up to the usual 8 bar.
- did I do it right?
- does the fact that I made it home (10 miles) without the tire being deflated means that the puncture is fixed and that the tube is safe enough to be used as I would use an unpatched one?
- is it safe to use the tube normally (at high pressures such as my 8 bar - of course this is a pressure supported by the tube on the first place)
- can I assume I will not have a problem with that tube on that specific hole (I know I can have another flat anywhere else but is it weakened enough for me to worry about it?)
I am sorry if this sounds so stupid but as I said, this is my first one, and I don't feel very safe with it: I am sorry but the fact that a thick homogeneous tube is supposed to bear a high pressure despite having a hole in it only covered by a thin plastic patch...
