Is it normal to wear out the rear tire with in a few months when using a trainer? Early this year I attached my bicycle to a trainer, around the December time frame of 2011. The rear tire and inner tuber where shot by March of 2012. Riding about 24 Miles per week. Is this normal with the use of a trainer? 

I have had the bicycle since 2004, and the tires were in good condition prior to attaching to the trainer. I have never had a flat, and the tread wear was good, probably had about 3000 Miles on the rear tire. After 3-4 months on the trainer the rear tire was bald, and the nylon belting was stringing on the inside of the tire, and the inner tube could not hold pressure long even with patching. 

I ended up just order a new tire and inner tube for the front wheel and rotated the old tire and tube set to the rear wheel. Should I plan to do this every time I hook up the trainer for the season?
This is common and is a result of the constant friction and increased heat of the small roller on the trainer. Larger diameter rollers will see lower degradation of the tire, but it will still be a problem.

Most riders I know use less expensive tires, or older tires that they no longer trust for use on the road when they switch to the trainer.
