I seem to have more bad luck with inexpensive tubes.

I usually shoot for some middle of the road tube. I just bought some off VO for $4 each. (Please don't tell me they are the same as these.. )

But seriously... I go with a top of the line tire, so I'm not afraid to spend more on tubes.

Have you ever been out on a cold, rainy day and had a flat? Better quality tires and tubes reduce the frequency of this event.
