    Tire cancer...

    My tire (Kenda Kinetics) has grown a little bubble on it. It is by the rim, and I dont know how it happened. I do have patches on my tube, put when I took the tire off the bubble is nowhere near any of the patches. The bubble is about 3/4" wide and tall; It sticks out about 1/2". I run my tires at 55 PSI, and the tire max. is 65 PSI.
    Should I stop riding it incase it rips right off or something?
    Get a new tire? (I don't have money)
    Or just stop worrying about it and ride.

    Sorry for no pics, but I think you can picture it in your head.

    sounds like the end of that tire. Bubbles/lumps are usually a bad thing.

    I bring it in everytime, so not left in sun.
    It goes away when I deflate it to about 10 psi and under (after I push the bubble in)

    it might have been stretched out when you hit something. maybe it's a weak spot, i would just try to keep the bubble in or just ride till it dies.

    Probly was stretched out on a weak spot.. there is no way to keep the bubble in, so I am just going to have to ride it till its done. I hope it doesnt cause injury.

    The tire was new in march.....

    That's weird



    I had the exact same thing happen to me a coupla weeks ago with a Kenda Kinetics tyre. I was at a reasonable pressure and going fairly hard and steep. I chucked the tyre and got a new one. I didn't like the look of it at all.

    If you can't afford new tires and they are still in good condition (other than the bulge of course), you might be able to salvage it with some duct tape on the inside.

    I put the part of my tube that has a patch on it directly under the bubble.... It helped some but that retarded bubble is still there...

    I agree. 7 layers of duct tape on the inside of the tire will do the job. The bulge will still be visible but at least the inner tube won't pop out and burst.

    I rode a tire with a 1 inch long cut in it for several months. I put many layers of duct tape on the inside and it held up fine and never bursted. Just make sure to cover it with duct tape at least two inche on all sides to prevent the duct tape from coming out too.

    As mentioned, the duct tape will work - longer than I ever thought. Keep an eye on the sidewalls, as you may get more.

    This happened to me with the older version Mich Hot S. I called Mich and they recognized the problem, had already made changes to manufacturing (claiming some new feature), and sent me 3 replacement tires (after sending them sidewall cutout of brand).

    The cause for me was lots of side rub on rocks. It just wore out the [thin] sidewalls, and happened to the tire on rear much more so. I wouldn't expect the Kenda tires to be nearly as bad as my experience - may be worth giving them a call.

    Roll some duct tape around your pump. You'll have some on the trail if it happens again. Make sure you clean the inside of tire before applying tape, as all will push through with pressure that high. It did for me in the 32lb range. If on trail, apply tape (to clean tire), rip it off and apply a few new layers.

    You should be able to get some more life out of it . . . Good luck.

    Tire exploded today......... 5 layers of duct tape, WITH the patch in the same spot....
    blew a hole through the tape and patch....
    I went off a 7 foot drop to rough tranny and about 30 seconds after I landed it exploded.... Nice and loud too.

    No more kenda's for me

    never had a kenda and the specialized tire(05 enduro model) wore out within 2 months and i didn't skid. i think that kenda might have been defective, you should email them and tell them what happend and see if you can get a new one free

    whatI said:

    I have a kenda kinetics 26x2.35 front tire. I have had it since early
    march 2005. I bought it new from my friend. I have had a problem with a
    "bubble" on my front tire the past few days. I run it at 55psi, and the
    max is 65psi. Just today, my kenda tire and kenda tube exploded. The
    hole is about 3 inches wide on the sidewall where the bubble was. I did
    expect this, becuase of that bubble on the tire, but I dont think that
    bubble should have happened in the first place; especially not on the
    front tire. I really did like the tire alot. I think this was definatley
    a defective tire. I do not expect a new free tire; but it sure would be
    nice, becuase I have no money for a new one.

    What they replied: ( only 2 days wait pretty good )

    Jake,
    Thanks for your email; regarding your Kinetics tire problem; are you
    using sealant in your tires? If so please contact me, my info is below.
    If you could also send me some digital pictures that would help expedite
    the warranty process. Feel free to email me if you have any questions or
    problems. Take care.........Mike


    I am taking pictures today.... rest of story later....

    I will be stoked if they give me a new tire for free
