Trainer specific tires are a high durometer rubber compound, which means they aren't at all for grip on the road but resist friction (disperse the heat, etc). You can use old road tires.

Clean the roller of the trainer with rubbing alcohol or glass cleaner to reduce friction. That black line on the roller is rubber from your tire, which in turn peels the rubber of your tire.....
i think this is the best explanation. it does make sense actually.
