Woo hoo!

Other teensy culprits which I've overlooked are those infernal threads from steel belted radials which worry their way up into the tire...NASTY things!

Hurray! I don't have data yet, but given all of the good advice here I manged to find the hole in the inner-tube and track it back to the tire. The piece of glass was really small and really hard to find, but I found it and plucked it out (with a toothpick). Now if I get an inner tube, it wont go flat, at least not right away!

+1 to something still in your tire. If you've run your hand on the inside, look for a dull grey spot on the outside, may be a shard of glass that has worked its way in.

Don't just replace it. You need to know why it failed. Under-inflated will often cause a pinch.

If you go over junk, that your glove and run it over the tire. Often this will take out any debris before it has a chance to work it's way to the tube. If you are experiences you can do it on the fly. If not just pull over, pick up the front then back tire, spin and let your glove catch anything. After riding I often check my tires for little pieces of glass and pick them out. The longer they are in the deeper they go.

A good Specialized Gatorskin or Bontrager Hardcase will set you back around $45 a tire, but most definitely a worthwhile investment, IMHO!

Thanks guys you are making me feel a lot better! When I changed the tubes I did a finger check of the inside of the tire and an eye check of the outside. I didn't see or feel anything, but my eyes aren't that great.

I am going to to take the tube out and see if I can tell if the hole is in the same spot. I wouldn't be surprised if I didn't pinch it while installing. Being my first install it wasn't as smooth as it could have been.

We also have lots of other glass and refuse on my ride, so I could just have had bad luck.
I might have to get some reinforced tires rather pay upfront than keep re-tubing myself.

Weight is very, very unlikely to cause blowouts. *At worst*, and this is a .0001% kind of chance, you could conceivably weigh enough to bend the rim badly and cause a puncture that way.

That said, though, when I was heavier, I did have a lot of problems with breaking spokes. That is the most likely weight-related problem you'll have. It can be "easily" fixed by buying a more expensive rim. It might be a good idea to look into one of those, anyhow, if your stock rim is single-walled.

My bike had single-walled rims and I was getting flats every 3-4 days between pinch flats from the rim and the ridiculous amount of glass in the street (there's a city ordinance that the local fraternities exploit -- an intact bottle is litter, a broken one is seen as the city's problem). I got some kevlar-reinforced tires and a double-walled rim with stronger spokes and it took over a year to finally get a flat. It wasn't cheap, and I'm poor, but it was the best investment I've made in a long, long time.

Oh, and if you happen to have plastic rim tape, replace it with cloth. It's a really cheap fix, but fabric rim tape is almost impossible to kill whereas plastic tends to break down rather quickly.

Loren !!! Hey you. (I just joined this team a week or two ago ... welcome aboard. But shhhh, do NOT let on about my talkative, rambly, I-make-no-sense-99%-of-the-time ways. Heh.)

But ... getting to your question ...

First, I whole heartedly agree with Don. Look elsewhere besides the weight. I will guarantee you that is not the issue with you.

Here's a few thing to check into ... likely it is one of the first 3 ... but there may be other things, perhaps someone else will think of something... and yes... LIST TIME! (By the way, this will be LONG.)

1) As Don said, check your tire before replacing your tube. If you have picked up a thorn or glass or something previously, if it is still in the tire, replacing your tube without taking the foreign object out will just repuncture it.

1a) There are several ways to check ... what I normally do is....I pull out the flat tube and make sure I take note of the tubes position in relation to the tire.

1b) I then slightly inflate the tube to locate the puncture. You can use your hand to lightly go around the tube to see if you can feel where the air is escaping, or if at home, fill your sink with water and dip the tube...bubbles will rise where the leak is.

1c) Then go back to the tire, and check that area. You'll want to check both the inside and outside of the tire. In fact, check the entire tire. One way to check the inside of a tire is to run a cloth...any foreign objects tend to snag the cloth.

2) Another common way to get flats after installing a tube in a tire is the installation process itself. And this tends to be more common on skinnier road bike tires (like yours). When placing the tube/tire on, you need to be careful not to pinch the tube between the tire and the rim. You can check if you did this, as this type of puncture tends to be sort of snake-like, with two holes close together.

3) Pinched tires when your tire is under-inflated. If you ride with under-inflated tires and go over a good bump or curb, it can pinch your tire.

4) Less likely - the rim strip (or rim tape) may be broken. Its the rubber (or other material) that goes on the rim that hides the spokes and spoke nipples in the rim. If it is broken, just replace. It cost 50 cents or so I would think.

5) Less likely - sometimes when you true your wheel (adjust spokes) they poke through the rim more...if that happens, they need to get cut...this would generally be done by the repair dudes though.

Ok ... enough of that rambling ... I hope you get your flat fixed.

There are many other things beside your weight which could be the culprit: are you closely inspecting your tire before changing your tube? There may be something still in there causing the flats. Over-inflating your tire may cause flats. If you ride your bike through areas where there is a lot of debris you may be picking up lots of flat-causing material.

Puncture-resistant tires can be a BIG help!

Hey all,

I have a kind of embarrassing question. I started riding my bike again about two weeks ago. I got in 1 ride and everything was great. Then I noticed my tire was really low before my next ride. I filled it up but it went flat during the ride. I replaced the tube. Then on my next ride I got another flat tire. So my question is, am I to heavy for my bikes tubes? If so, do they make tubes for heavy people or am I stuck with a really nice bike I can't ride anymore? I tried to find specs and weight limits for my tubes, but the nitty gritty facts seem hard to come by.

The tube I just blew (which I bought yesterday):
Bontrager, 27x1 3/8 (700x35c-44c), 36mm Schrader. Part number 64790.
