    rear tire blowout

    I'm riding on 700 x 35c tires. I put about 750 miles on them. I keep them at max pressure as stated on the tire wall. I weight 250lbs, I noticed after the big kaboom that the tire separate where it meets the rim, well , right above the rim, where that little flat portion of the tire start to go round.my explanation is clear as mud hey ??? I could see that the cord let go and the tire separate on about 1 inch long.

    Am I too heavy for this type of tire ? The wheels dont seems to suffer . Or 750 miles is what I should expect from the Innova IA2209 ? I'm I stressing the tire too much by keeping them inflated to their maximum ??

    Thanks for your good advice guys

    Personally I never go quite to max pressure. I like a little wiggle room

    Sounds like a bad tire. It should handle your weight and Max pressure with NO problem.

    I think I'd try a different brand though.

    It sounds like a bad tire or your brake pad was rubbing on the tire. Check the pad alignment (assuming rim brakes) to make sure that isn't the issue.

    I'd recommend backing the pressure off 10psi. I had two blowouts the same as yours on brand new tires; backed the pressure off a tad and haven't
    had a problem since.

    I had a similar blowout a couple of months ago. Riding down the street and BLAM, about a 3 inch section of the sidewall had split.
    Michelin City tire with about 800 miles on it. I usually run about 5 psi lower than the max pressure.

    No rubbing on tire , no sharp edge on the rim, I'll try with the pressure 10 psi below the max. Finnaly I'll try too loose 50 psi................oups.........pounds that should help also ;-))

    Anyway thanks for your input guys !!

    8 blowouts in past two weeks on 700 x 23 at 120psi, I weigh 230. Had gone a year without a blowout. Bad string of luck?

    There has been a lot of stories around about counterfeit goods being sold via the net.
    I wonder if there are counterfeit tires among those goods?

    If you watch more TV, and ride your bike less, you should have fewer blowouts. Tyra Banks and Dr. Phil are good shows for a wanna be cyclist. I'm particularly interested in Dancing with the Stars.

    I'll give skilsaw the benefit of the doubt on that, because if I don't he'll sound kind of like a dick/non-clyde-friendly. My bike-to-work commute is 30 miles round trip and biking is getting to be unreliable transportation. The blowouts were happening in the same spot--construction area--so maybe there was something on the ground I wasn't seeing. I popped Wednesday on my other bike during club ride and that was after running over a 1in-rock that I didn't see. I might just have to face facts that I'm never going to be college-age again and go to wider tires. I think the old Bianchi would fit 28mm tires. Not sure if that's a big enough difference though. Laserman, I bought the tubes at LBS and they say "Specialized" on the box--hope they're not counterfeit. If they are, I'm paying WAY too much for them.
