I give up, for serious yo's.

SouthernBelle and I have now gone through three tubes and two tires. My front tire utterly refuses to stay inflated.

We had both of us trying it out- changing the tubes, then the tire, and yesterday we thought we had it fixed until it went flat on me. On hill day. On a main part of town with lots of traffic at night.

What to do? I have ordered a new tire (the brand new one on it the first time really is defective) and the other one should be fine.

We've checked sizing, puncture possibilities, and wondered if the wheel is bent. It was just trued two weeks ago!!
