Just so you don't feel like you're alone, I experienced exactly what you are. I put on an Austone. It was just before going on a 5k trip and there was no way I was going to ride the bike under those conditions. 2 up with trailer. I pulled the tire and went back to an E3. I really wanted to go darkside but there was just no way. 6 to 10k miles to break the tire in? Not. This is not a dig at car tires. I probably will try it another time. Just wanted you to know there are others out here. I know of at least 6 others with the same problems. Most don't get reported.
