    For the first 8 months of having my road bike, I was riding on 700x23 tires.. never a problem.. then, about 3 months ago, I started getting flats on my rear tire.. like, constantly. About 9 or 10 in 3 months. The LBS said the tire was still good, so he recommended using tuffy liners. Which I did. 3 more flats. The last two were caused by my installing the liners wrong. Last friday, I had another flat and had a nervous breakdown down and bought a new rear tire - a panaracer pasela 700x28. I rode the bike home (3 miles) rode it to work on Monday (3 miles) and got ANOTHER flat on the way home. I'm about to lose my mind. I'm still using the tuffy on this tire.. and I have a feeling the liner is to blame again. My question is, are these liners all their cracked up to be? I cut them flush with each other, but I think when the tube was inflated, they separated and had about a half inch gap between the ends. How do you install tuffys? Are speed skins better? (I heard someone talking about them at the LBS just now.. when I was buying ANOTHER freakin' tube.)

    Next.. I have to vent a bit, and hopefully somone else will tell me they've done this so I'll feel like less of a ******. Since I've been riding my beater a lot lately (see previous paragraph) I've put some work into it.. first thing was to replace the crappy pedals... well, I must have crossthreaded the drive side pedal and it was at a slight angle. After mashing up the over pass on the way to work, it had completely stripped the crank arm and the pedal fell out. BAM.. right in the middle of a mashfull down stroke.. I wobbled, almost fell, people pointed and laughed, pride was hurt.

    I pedal all the way to work with one foot (using the other foot to push the pedalless arm around on the drive side) and take the bus home to get my extra set of beater cranks. The next afternoon I stand in the 105 degree heat and 100% humidity and swap the cranks out ... getting violent at times because I was so hot and soaked and dripping with sweat and annoyed... well, anyway.. I must have crossthreaded the new driveside crank AGAIN and now the pedal is all wobbly after 10 minutes of riding. Do they make cranks out of frickin' butter? I know it happened cause I was rushing and frustrated both times.. but honestly.. it's not like I've never screwed in pedals before! Uhg! Please tell me this has happened to someone else?

    Regarding the problem with flats, have you checked your rim tape? If there is any imperfection with the tape, you will continue to flat. When you take out the flatted tube, have you inspected it to find the hole? If the hole is always on the rim side of the tube, then look at the rim tape and the rim itself to check for anything remotely resembling a sharp edge. On the pedal subject, did you use the same driveside pedal on the second crank? If so, perhaps the pedal threads were damaged during the first crank problem, and thus messed up the second crank. Probably a long shot, but maybe. These things haven't happened to me, but I did ruin a crank arm once because I thought it was tight on the bottom bracket when it wasn't, so I hogged out the splines. Yesterday, I snapped the head bolt while I was putting a new stem on my bike. So I know the "So annoyed at myself" feeling. Hope this helps, good luck.

    Sounds like a plausible cause to me.

    I had a pair of flats on my MTB in two days, ended up ditching the tire, it was time for something less aggressive anyway, and no more problems.

    Try coating the new tubes with baby powder when you install them if you aren't already, it allows the tube to move around inside the tire and rim to find it's "happy place". If it can't move at least a little bit, it will wrinkle and cause a flat, in my experience.
    It's either old age or I need more suspension...

    I checked the tape... it's all good. The holes are always on the outside tire side. I figure I was right that the tire was getting too bald and I shuold have listened to my gut rather than listen to the LBS guy when he said the tire was fine.. he probably was looking to get me to buy the tuffys, THEN come back and buy a tire from him. ha! Didn't happen. (Well, I bought the tire from a different store.)

    Nope, it was a different set of pedals as well. (new cheapies fom the LBS - $4)

    I;'m gonna go linerless for a while with the new tires - since that lasted me months with no problems... gonna stop by the co-op tomorrow and pick up a new crank... and go super slow in the A/C when putting it on!

    I've heard that before, and I've never done it. I will definately do that tonight. Sounds like a great idea.

    Having that many flats in such a short period sure seems suspicious. Are the routes you ride just filled with broken glass and tacks or what?

    Is there any possibility that you are damaging the tube in the process of changing your flat? It's surprisingly easy to do (and you don't need baby powder to avoid it, just a slightly more careful hand and some patience). Have a look on http://www.sheldonbrown.com/flats.html, specifically under the heading "Re-installing the Tire".

    Also, probably obvious but when you get a puncture flat, you have to clean out the inside of the tire, make sure whatever was puncturing it was actually removed. A buddy of mine was getting flats like every ride, sometimes 2 or 3 in the same ride. He would just change the tube but neglected to run his hand along the inside of the tire . . . turned out there was a (very tiny) thorn poking through, causing a slow leak. Once that was removed, the problems went away . . .

    Different tires may also be useful. Touring tires are often more flat resistant; I've run different touring tires for many many miles with few flats. I'm currently running Continental Ultra 2000 + K "GatorSkins" which have a Kevlar belt that is supposed to help prevent flats. So far so good (looking for some wood to touch; talking about flats makes me nervous!).

    If you are a big guy, pay special attention to tire pressure, and run larger tires to help ward off pinch flats.

    try some bontrager hardcase tires or specialized armadillo. I ve used both for over 1500 miles on chicago city streets and have yet to get a flat. p.s. keep that tire pressure on the high end or slightly higher than the reccomended range, no more pinch flats.

    we don't cut tuffys ends to butt against each other, we "feather" the ends on a bench grinder so there are no sharp edges to chafe into the tube. works very well. keeping tire pressure up also prevents them from shifting/chafing, along with the other benefits.
