This ever happened to anyone?

Out for a little jaunt on my World Sport Sunday eve. Went around a corner and skidded to a stop with the back wheel locked tight against the rear fender, by what I couldn’t tell.

Figured maybe a stone or something was lodged between the fender and tire, but after a couple of attempts to free it, made the call of shame for a ride home.

Put it on the bike stand and let out some air (which I should have done out on the road!), removed the wheel, and the pics show what I encountered. The pic was taken with about 40 psi!

Don’t like thinking about what would have happened had it been the front!

Tire was installed last year but I only ride the bike occasionally, so only 200 miles on the tire. Didn’t see any signs of tire rubbing against the fender (one photo shows the tire off the wheel where the bubble occurred.) and I always check before riding for proper inflation, brake drag, and on bikes that have fenders that both front and rear wheels spin freely.

Got em’ from Niagara about 3-4 years ago, and purchased an extra last year (not the one shown), but now I’m hesitant to ride them.

Anyone else have a similar experience, especially with this tire?

Serves you right for using a red tire. :D

That look like it was defective from the beginning. I wonder how long it sat in Niagara's warehouse.

I don't think long as....

....tire was very flexible and showed no signs of again like cracks, etc.

looks like tire separation. I used to see this a lot on OEM Uniroyal car tires when I worked in a tire shop back in the 70's.

I have a couple of sewups with casing failure but not that severe...

This one had a mini bump but I'm sure it would have blown out.

I carry some of the super tough plastic material that USPS envelopes are made of just in case I ever have to put a boot in a tire to make it home.

On a ride one time, my buddy had a casing blow on one of his high pressure "zoomy" tires. All we had between us were $20 dollar bills to use as a boot. Usually a $1 bill will work just as well... ;)

I ran those same Cheng Shin tires (mine were white) on a couple bikes for about 1500 miles til one failed (nail puncture), so they are not all inherently faulty. They are pretty cheap tires, though.

Tyvek. They use that material for so many different purposes, it's amazing stuff.

If it moves, it's definitely a baby graboid.

It's Tirerhoid. Put some Prearation "T" on it.

Thanks Lascauxcaveman for an informative answer. I do harbor some fear that it might be a bad batch. i've run these cheapos before (black) and had no probems, so hopefully it was just an anomoly.

As to carbunkle (don't know what that is), cyst, hernia (been there done that), or having a tire that's happy to see me, I looked in the Park Tool Repair Manual
and saw none of those terms so I assume The Waco Kid from Blazing Saddles | Anyclip

I also have put many miles on those tires. Too bad they only come in colors though.

John E 08-11-15 06:56 AM

This is why tire clearance is a good thing.

In the 1960s we used to watch for bubbles in tires as signs they should be replaced immediately, but I have not encountered the problem on my own bikes during the past 20 or 30 years.

The one time I skidded to a stop like yours I caught a small board in my rear spokes. I kept the bike upright, but the experience was scary enough, without contemplating what would have happened if it had locked up my front wheel, instead.

I've seen cheap tubulars do that many times, but on a smaller scale, as also cited by verktyg.

What has happened is that the tube has slipped past the pressure-containing casing of the tire, do to some discontinuity/irregularity in the tire casing. Very fast production rates using coarser grades of casing fabric tend to cause this, though I myself have had only good luck with these seemingly-exact (C-740?) model of Cheng Shin tires. It is almost unbelieveable that the tread rubber is containing the pressure by itself, so I am assuming a low pressure was used(?).
