My bike came with some cheap vittoria zaffiro tires. I use a somewhat better set when I'm mostly on the road in spring, summer, and fall, and in the winter when I'm mostly on the rollers I put on the zaffiro's. I use a significantly higher pressure on the rollers than on the road. I have seen little or no wear to the zaffiro's. If I go from the road to the rollers, I wipe the tires down so there isn't any grit getting on the rollers.
