Double Tubing: The Third & Final Update
I've had three punctures in the past 5 years all 3 of them from staple
like wire that created an instant flat, once even with slime. The wire remained in the tire until I extracted it in all 3 cases. All 3 of the flats were in the past 8 months and -- this is the clincher -- all 3 were on the same 200 yd section of highway. Apparently a sloppy contractor in the area drives off with staples raining off his truck. The first flat was what precipitated double tubing and double tiring in the first place. Today I got the 3rd but I'm a little lackadaisical about keeping both tubes inflated. The good tube had squeezed the air out of the tube with a slow leak. When the good tube punctured the tire went flat. I pulled out the staple as usual and went to the NAPA store across the street where they had a small compressor. I picked a valve stem at random hoping it was the tube with the slow leak, watching the gage for a few seconds to see if the pressure would drop. I got it on the first try Anyway, this above is the way double tubing should be used. Just pump up just one tube and carry a pump. When you top off once every 2 weeks or, in my case, every 2 months, alternate between tubes. Deflate the tube that you were riding on and inflate the other tube. This eliminates the hassle of getting the same volume in both tubes and provides a check so you can always be sure when you take off in the morning that you have two good tubes. Bret Cahill |

I told the local bike shop owner yesterday that I couldn't afford to get a flat for the next 6 months. It's too hot to stop. Bret Cahill |

Double Tubing: The Third & Final Update
I just took the tubes out. The holes were oriented longitudinally,
both in one tube. If the staple had been turned right 90 degrees it may have punctured the flat tube and, had both tubes been inflated, would in all likelihood have flattened both. For most people the best way to use this is to keep one tube deflated and carry a pump. In certain situations where carrying a pump and stopping for even a minute isn't acceptable then spend some time carefully inflating both tubes.

Double Tubing: The Third & Final Update
The staple went through the other [rim] side of the tube as well.
This tends to validate the original idea of positioning the tubes side by side -- instead of concentrically -- to prevent both tubes from being punctured.

I marked the tube/side that has the slow leak. I'll just pump that up
every two weeks and see how long it takes for the other side to go down. Bret Cahill The staple went through the other [rim] side of the tube as well.
