What Supcom said.
Plus, on my trainer I use an old tire that has been squared off/worn from normal outdoor riding. That way I am not prematurely wearing a good tire. Seems to me that a trainer will wear a tire faster, but I also MAY have the wheel tension to tight.
As for boredom, something I think, we all suffer from on these trainers. Play energic music to keep you movin. Watching TV or a movie I find does not help, I will eventually slow down.
