+1 Excessive tire wear on a trainer is due to either too much or too little pressure on the roller. The former causes excess flex and the later too much slippage.
I set mine so the tire just slips very slightly when I grab the wheel and give it a hard yank circumferentially. I'm on my third year and well over 1000 miles on the same rear tire that was worn when I put it on the trainer.
