Thanks for the advice all. I rode my tires last night, and it seemed to work fine. When I got done it smelled like burnt rubber in the basement and the tires had dots on them which you can see in the photo that were not there before. Long story short, my trainer tires are the obvious better choice compared to these soft tires...but doesn't look like too much damage to the rollers or my tires if im only ridding the rollers a 3-4x a month with these tires.
