you could look into a spare wheel setup for just the rear that you could use. you could just get a cheap one for training. you might also consider another bike. you can get a an old rigid for dirt cheap. thats what i run on my 1up. I have an old mongoose with a specialized nimbus tire on it. The fsr is for the dirt. The 1up trainer is pretty quiet with a slick though. I really enjoy mine. good luck.
