Wasn't sure where to post this, but I've come across a 'new' problem I hadn't experienced before [I've been riding performance road bikes for at least a dozen years, so I've seen my fair share of tire problems].
In the last two weeks, I've experienced the clincher function of several tires [or rims] 'fail' after inflating the tire, of course, causing a 'blow out' of the tube. The tire just pops out of the rim.
This has happened 3 times now, with 3 different tires and different rims. The tires were all 23 mm. Two of the tires were gatorskins, the other rubino pro. The clincher rims have operated fine for several years with no problems.
One time, and I assumed I did not seat the tire properly in the rim [it happens I suppose]. Twice, I assume just bad luck. But 3 times on 3 different tires...and now I'm concerned I'm doing something wrong? But why now, after all these years, and countless tire changes?
The one thing common to the tires were that they were relatively new; the gatorskins totally new, while the rubino pro maybe a few hundred miles on it. They are all rated for 120 psi, which is what I inflate to. At least twice the failures were delayed; that is, several minutes AFTER I inflated...say after 10 minutes or more had gone by.
I think that's what's scary to me; that everything 'looks' fine but can fail 'later on'.
It must be I was not seating the tires properly, but now I'm sort of concerned and gunshy, that I could have a 'blow out' if the clincher function fails at +30mph careening on a downhill or something. Needless to say, I'm double and triple checking the seating now [which I did anyway]. Common flats are just a nusiance...but 'blow outs' I think could be dangerous.
Any ideas or advice on this? Could I treat inside of rims somehow to ensure 'sticking' power of tire clinch? It's really a puzzle why this is happening all of a sudden. The 'kapow' of these things blowing out is like a *** going off, .
