Let's play diagnose that problem!
 

I was riding today and I felt a large clunking in my rear wheel. At first, I thought my wheel was thrown out of true. I came to discover a HUGE deformity in the tire. Pictures are below. Sorry for the bad quality and the feet in that last shot. :)

Is this a problem with the tire or the innertube? When deflated it looks normal. I tried to massage the area, but it didn't do much. However, I haven't removed the tire yet because it's incredibly difficult to get tires on and off of this wheel, and I'm a little reluctant because I always seem to pinch an innertube or 2 getting it on. :(
Any suggestions? Thanks!

Broken/weakened tire bead.

Well that sucks. These are relatively new! Thanks. :)

I think:

Take the tire off. If the rim looks good, replace the tire. If the rim is foobarrrd...well time to go shopping.

It isn't the tube. I'm guessing that you find the tire is done.

Thanks. How do you think the bead weakened in that of all places?

I have had a tube do that, but it was because it got folded somehow in the tire.

I'm pretty sure that if it was a problem with the tube, it would have popped by now.

Take the tire off to check- just be careful when you put it back in to seat it correctly and you shouldn't have any flat problems.

Overinflation or manufacturing defect is all I can think of.

Thanks. I just removed the tire and the bead is bent in some places, but only because it's a foldable. At least it seems like that would be the reason it's bent. Because it isn't only bent in the place with the tire problem was.

Good news is you should probably be able to use the same tube. Does that help the bum tire blues?

You must live alone. If my girl saw me with my filthy bike wheel on our sheets, I would be living on the street right now. :D

Maybe it's just the bead slipping on the rim then. Clean the rim with some soap, dry it, and then remount it.

Cheap tire? I know that car tires do that due to a weak spot in the rubber causing the rubber to expand sort of like a bubble. Very common when there is sidewall impact.

Yep, that helps!

Yeah, I do. XD

Thanks, I'll give that a shot! I hope it works!

My mechanic despises tire levers....he claims they can really mess up the bead when not used properly. You said these wheels are hard to get a tire on and I bet you had to use a tire lever....you probably bent the bead with the the levers.

I guess that can make sense. How do you get tires on tough wheels without a lever?

Had it happen before, it's a problem with the inner tube. Well, not really a problem, all that happens is the inner tube pops out underneath the 'lip' of the tire. Deflate it a bit and push it back in...I think.

with your hands...there is definitely a trick to it and I'm still mastering it.. basically you use the palm and heel of your hand to put pressure on the tire across the rim...it is pretty hard. You use the reverse movement to take the tire off the wheel.

I had the interior wall of a Specialized All Condition Pro fail (twice) which resulted in a very odd bump on the surface of the tire. You'll have to pull the tire to check it, however.

To remove a tire with your hands... You need to empty the air obviously. Squeeze the tire beads into the center channel of the tire starting on the opposite side of the rim vs. the valve. While squeezing the beads into the center of the tire pull against the tire to keep it taught in the center channel. Work your ways around the tire. When you get to the valve side you should have some slack. Use your palms and rotation of your wrist to pop the tire off the rim.

Thanks! I'll try that, though it looked a lot easier with Ksyriums than with mine. :)
