Mystery of the tubes that "blowed" - Part 1

This post can also be appropriately titled, "The devil is in the details". I am usually a cautious, but there are times when "even I" make blunders.

Two weeks ago, I noticed that the bike on the trainer, had little air in the rear tire. So, I, "the one who knows all about bicycles", decided to inflate the tire. The inflation was a breeze. I put in 55 odd PSI into the tire. All was well for about 10 minutes. Then I heard this "explosion", like one made by a fire cracker. I looked at the rear tire and it was flat.

I knew the rear tube had "blowed". So, I took the wheel off and examined the tire. Boy, did I find a big hole in the tube. So, I did what a decent human being would do: ordered a pair of tubes for the bike. My wife told me that these tubes haven't been changed in close to 15 years or longer. It seemed to make sense to replace the tubes. So, I did.

A couple of days later, when I got the tubes, I popped a new tube in the rear tire, aired it up. And, 5-10 minutes later, I heard that familiar sound: dang - another tube explosion. Now, this really "blowed"!
I thought I was doing everything right. I checked the inside of the tire for debris, checked the rim tape for possible tears, which could expose a pointy spoke, all that good stuff.

But, yes, you guess it right: I DID NOT CHECK THE TIRE FOR WEAR, ESPECIALLY THE SIDEWALLS OF THE TIRE!
While my blunder cost me a tube, which I would have vulcanized, back in the day, I was happy that it didn't blow while we were on the road. Plus, I found the front tire to be of questionable condition as well.

This was indeed a valuable lesson. The bike couldn't be put back on the trainer.

What did I do next? This will be talked about in a future post, I guarantee ya.



Peace :)
