Flats....this just ticks me off...(8 posts)

Flats....this just ticks me off...asphalt assault
Jun 13, 2003 5:29 PM
So I'm out for a spin today and had the rear go flat about 8 miles from the house. I had a spare tube, changed it, pumped it...still leaking. I called the wife to come and get me and when I got home I checked the inside of the tire...nothing. Turns out I'm pinching the tube while installing! grrr.

Looks like I'l have to stop by the LBS for a crash course in road tube changing, never had this problem changing a MTB tube. GRRRR...that was my last tube!

Crap, guess I'l just have a beer.

I hear ya. Look for smaller tubes at your LBS. If your using 23 tires, look for tubes that are 19-23. Some tubes are made for 23-28 and they are easier to pinch underneath the bead.
It's a lesson we've all learned the hard way...biknben

Do your best to avoid having to use the tire iron when putting the tire back on. With some tire/rim combos it is just impossible though. If you have to use the tire iron be sure the tube is out of the way.
Is the tube inflated semi-firm while you pry?cory

Putting a little air in the tube (just blow it up about as hard as you can by mouth) will help to keep it out of the way while you lever it on. Otherwise it's just a matter of pushing it back as you go.
Dust on some baby powder?Kerry

If you have new tires, it may be that the rubber is sticking to the rim and making the install harder, increasing the chances of pinching the tube (w/ or w/o tire irons). Try dusting the bead with talc to make things easier. Don't feel bad, my first set of modern clinchers (Michelin on a Campy rim) went on so hard, I did the same thing. Embarassing, but you get over it.
Thanks guys, time for a technique change...asphalt assault

I went to the shop and the guy put a tube in using no irons and a little baby powder...looks like the way to go!

All you have to do is blow some air in the tube to allow it take shape before you install it. The nas you install the tire, work the tire latrally on the rim. This will loosen portions of the tube trapped under the bead of the tire.

after the tyre & tube are mounted (but not pump inflated), I push the valve up into the tire to make sure that the tube is not pinched at the valve area and double-checks that the tyre is seated well in this area. (just a habit of mine) I also sprinkle the baby powder on the tube then wrap it tightly in Saran wrap and secure it with scotch tape...and I thought I was the only one who inflated the tube by mouth before installing :) IMHO, the biggest cause of pinch flats is rushing to fix the flat and not checking the installation....
