Bent/kinked rear tire?
About 10 miles into my ride on my road bike the other day I heard something rubbing on my rear tire. When I stopped to investigate I noticed that the rubber tire itself was kinked. There are no broken spokes and no visible damage to the rim (although I haven't yet taken the tire off the rim to investigate). Any idea what the problem could be? Am I going to need a new rim?
Thanks!
Thanks!

is the tire properly mounted? you could either have a spot where the tire is not seated all the way into the rim or seated too far. depending on how old the tire is it could be a few broken cords

+1 I bet the bead on the tire is not properly seated. I know it has happened to me, usually when I use my air compressor to inflate a new tire/tube combo, rather than using my floor pump.

I had a tire snake on me at 2800 miles

Tire snakes: are they poisonous? How did you get it off you?
OP: not certain from your description, but yeah, either it's not (or wasn't) seated properly, or maybe there's a bulge or something in the tire. Picture?

To check for proper seating of the tire: look at the sidewall of the tire just above the rim. There should be a little ridge molded into the rubber. This ridge should sit just above the outside edge of the rim, the same distance all the way around.
If it is and the tire is still wiggly, the tire fabric is coming apart. Replacement is the only cure.
If the ridge dips below the edge of the rim, this is a low spot. Deflate the tire most of the way and you might be able to pull the low spot up. If there's a high spot, deflate the tire all the way and stick a tire lever in there- the tube is probably trapped between the tire and the rim. Then re-inflate in increments of about 10 or 20 pounds, rechecking the tire after each increment.

When you inflate your tyres, you should do it in two stages; first put like 10psi in and spin the wheel, checking for straightness of the tyre. If it doesn't look good, you need to work your way around the tyre from each side hauling the bead into place before continuing to inflate.

Haha, thanks for all the replies to my ambiguous post. I've been away for a bit, but here are some pictures to help understand what I'm talking about. My apologies if the quality seems poor.
The tire appears to be fully seated in the rim, and (out of necessity) I rode on it like this for ~30 miles. Because of the bend the tire rubs slightly on the brake as it passes through. It holds pressure just fine, it's just---kinked. Anyone seen this before? Thanks again!

Is it an older tire? An old tire did that to me a while back, even produced a slight hop as if the rim was damaged. Gonna need to remove the tire & check the rim to b sure.

I had a tire do that to me last year. The sidewall was giving out. It looks like you've got a good number of years or miles on it. I'd say just replace it, and save yourself from worrying about it.

Yep, looks the sidewall cords are starting to go, time to replace it.

I've had this happen to me before. Time for a new tire. Trash that one.
