I don't plan on riding the trainer a whole lot since the weather here is usually pretty good year round. So changing the tire back and forth would be a pain. ...QUOTE]

I use a spare rear wheel for riding the trainer. Its not unsafe to use the same tire, but it increaes the probablity you will flat. Swapping a wheel is easier than changing the tire back and forth.
