I ride on a trainer on occasion, and I prefer to ride out doors. I use a different tire for the trainer because it ruins tires very quickly. I have noticed that I am getting frequent flats on my rear tire, and I believe it is related to transitioning between the trainer and the road. Am I doing something wrong when I am changing my tires? I had to replace the tape in my rim because a hole got punched through near one of the spokes, so that might be a contributing factor. Next time I change my tire I will look at my tubes to see if that is where it is going flat. Could it be bad technique when changing tires?
