Is this tire toast?
 

Hey folks,

After changing a tube out, I am having a problem getting the bead seated properly to the rim. I've used soap and water and inflated it to about 120psi (max rated 85psi), but it still won't pop all the way in to the groove.

Upon further inspection it seems like the "line" on the sidewall is almost peeling off. Is this something that should just be replaced?

Thanks for the help

It wouldn't hurt to replace it. If it does come apart you have to worry about the tire binding in the frame/brakes. Also I would think if the tire fully fails the tube will expand and pop.

Not toast yet unless there's a through slit or hole in the casing. But as mentioned why chance it. Andy.

It's just starting to get golden brown. There may be some life left.

But I suspect that your brake shoes may be the toaster. Remove the wheel and feel for a raised edge on the tops of the braking surfaces. If so, it's because the shoes are overhanging the rim and rubbing on the tire.

BTW- if you have cantis, it's possible that the properly adjusted shoes don't tough the tire when applied, but because cantis open upward they might be rubbing slightly when open.

It's just an educated guess based on the tire, so I may be wrong, but it's worth checking.

If it isn't the brake, you still want to see what's rubbing the tire.

The long continuous abraded line just above the rim's edge is classic for brake shoe wear. However, if the brake shoes check out, you can get similar damage if the tire is ridden under-inflated for long time.

Whatever the cause, the wear pattern isn't normal, so you need to find what's happening and deal with it, or you'll be toasting tires all the time.

i think youre wrong fran
the seam is a red herring
the wire bead is kinked

You might be right. I'm just commenting about the long abraded line I see in both photos. The bead looks fine, but a photo isn't the same as having the tire in your hand.

In any case, I like herring, so red herrings don't bother me much, they're more of a pleasant side dish.
