What is wrong with my tire?
I just got back from a ride. Midway through the ride I was noticing a slight thump. So i got off and inspected my front wheel/tire. I thought my eyes were screwy but in fact the tire is crooked on the rim. THere is also a tiny cut in it in this area.
I am pretty sure the rims are ok because i just bought the wheels last week and this was the second ride on them. I assume new tires are in order but what happened here? These are continental ultra 2000 tires. I am through with Conti tires at this point. http://f5.putfile.com/5/12610024088.jpg |
Many years ago I had a tire do that when the cords in the sidewall started breaking. I'm not sure if this is the case here, but might want to look.

first thing to check is whether the bead is seated correctly in the rim.

I had that happen to a tire a while back. I caught a thorn and it made a small cut in the tire (the tube remained intact). As best I could tell the air pressure from the tube was causing the tire to bulge when it was inflated since that part of the tire was weaker and can't hold the tube properly.
I ditched my tire, but I think it could be fixed with some sort of patch on the inside of the tire wall. FWIW, I rode ~60 miles with the bulge and experienced no problems other than the thumping. |
We used to call those "bubbles." Assuming this one was installed correctly, I fear it is time for a new tire.

If the tires came with the new wheels it may also be time to have a chat with where you got them.

I got a tire like that...in the trash bin.

Last summer I bought a pair of Panaracer Stradius Pros from Perf, and one of them was like that right out of the box. I posted about it on here, but the attached pics have long since gone the wayside. Anyway I returned them from Perf and spent the extra $$ on some Conti GP3000s.

I had this happen when I hit a rock or pothole way too fast, destroying the sidewalls. Portis, do you recall hitting something or feeling a jolt stronger than the run-of-the-mill road bumps you usually experience?

If while remounting the tire, it felt easier than a new tire, the bead may have stretched.
Also, I'd check your brake shoe alignment to make sure that the pads aren't making contact with the sidewall. I agree with the others, the tire pictured above is trash. |

In quite a few years of riding I've had that happen twice. Both times, like SCRUB said, the sidewall threads had been damaged & were separating, allowing the pressure of the tube to bulge the sidewall out where the threads were separating. You can probably see what the threads are doing if you use a magnifying glass on the inside of the tire. Both of mine started with a small cut in the sidewall.
Continentals are great tires.... it can happen with any brand, but tires with more threads-per-inch probably have more resistance to that kind of failure. In my experience, all sidewall repairs are temporary. |
I had an exciting experience a few years ago with a tire just like that. It had a slight bubble in the sidewall where some of the cords were damaged. As I was riding down the road, I heard a loud bang, which I assumed was a firecracker. Then I felt myself riding on the rear rim. It had blown out several inches of sidewall. Fortunately I was only a mile or so from home, so I walked it the rest of the way.

Didn't anyone tell you about the tires and the bees? You are going to be a tire daddy, Tire mommy is showing.
Or, it may be just a very satisfied tire after swallowing its prey whole. A python in the everglades did that to an alligator and it eventually exploded. I wouldn't want to be riding your ride if and when that happens. |
