How did he get the flat?

My GF and I were out riding today and a guy stopped as he passed us when he noticed one of our mini pumps. He said another guy was looking for a pump around the corner, and sure enough there was a guy with an older Haro mountain bike with a flat tire on the front. He said he'd been riding for a while, and noticed the tire was flat after a while. He hadn't been riding in ages, but said the tire did have air in it when he left home. He was sure it would hold air after we pumped it up, and sure enough it did. He went the same way we were going for a while too, so I knew it held air for a while. How could the tire loose air while he was riding and then hold air after we pumped it up?

I've seen thorn punctures where the hole is small or is more like a flap of rubber - making it a very slow leak. It takes a while before you notice it.

I've also had some slow leaks from an improperly seated valve. I presume a bit of dust got under the valve seal creating the leak. Pumping it up can dislodge the dirt and eliminate the leak.

I've had slow leaks on loose Presta valves which screw into the valve stem. I've also unscrewed the valve from the stem as I unscrewed the plastic cap. So now when I pump up the tire or check the pressure, I make a point to twist the valve to make sure it's screwed in all the way. I also make a point not to torque the plastic cap on too tightly.

I've had leaks that took overnight to go flat. Slow enough that even the "tube in a bucket of water" method took a while to make a bubble. It happens.

Lose is spelt with one o. For example, you lose at spelling.

And loose has two "o's". For example, loose Presta valves. And the word spelled has no "t".

Perhaps you should not be so quick to criticize.

It does in those goofy countries that haven't adopted our progressive version of the English language. Wait, how did this thread turn into spelling pedantry?

[QUOTE= Wait, how did this thread turn into spelling pedantry?[/QUOTE]

Because some some people can type quicker than they can think, and/or have nothing of value to contribute to the thread, but feel compelled to show their own ignorance because they have nothing better to do. I'm sure we'll see more of this as the economy continues to sag and dead weight lose their jobs first and have nothing better to do with their time (er, uh, should that be "loose" - I so confused now).

I'm surprised I wasn't "corrected" for my use of the the word "too"...

Funny how this thread went from a slow leak to a rush of HOT AIR.
