Wobbly tyre, straight rim.

rockmonkeysc

I had a bit of a mid race lie down today when I badly cased jump resulted in me getting bucked and then bouncing over the bars.
When I got back on I noticed a big kink in the front tyre and thought I had buckled a wheel. On inspection the wheel is true but the tyre isn't. I took off the tyre and refitted it. There is still a big deformation in the same place on the tyre (not the same place on the wheel).
Any idea what I have done to it?

Tyre, wheel or bike?

Tyre, if the wheel is straight.

Everybody needs a new bike.
I guess if the wheel is true and the tyre is seated evenly you must have damaged the threads in the carcass and it could go bang any time.

If you take the tyre off, refit it, pump it up fully, let it down again, pump it up to a fairly soft state and then pinch the tyre and wobble it this way and that way all the way around (you're making absolutely certain that it's seated right) let it down and pump it up again . . . . and it's still like it, then it's busted. Get a new one. If the previous actions sorted it out, it just wasn't seated right.

Seen it happen more than once. Only way to fix it is to buy a new one. Continental's are the worst for it IME but others do it too.

Sounds like a busted tyre to me, i had a similar issue but there was visual damage to the tyre, like frayed fabric, but i suppose there isn't nessesarily any visible damage, and i had no deflation, if the structure /weave is busted, depending on the type of tyre it may have a robust outer skin which could hide structural damage.

I watched a documentary video about car tyre manufacturers a while back , and the building that goes into them is quite eye opening, they are not just rubber rings with some wire embedded for strength..

I'm not saying bike tyres are as heavily or strictly built as car tyres due to less forces involved, but it wouldn't surprise me if many of the same construction principles are applied to some extent on a smaller lighter scale for high quality branded bike tyres.

busted tire, save some cash and buy a new one and make sure you dispose it, don't put it on the pile with the lightly used ones...
