I just purchased my first set of rollers, A set of Travel Tracs. After closely inspecting the rollers themselves, I noticed there is a textured feel due to grooves in the aluminum. I presume this is to help with traction so you don't slide from side to side, but I am concerned the grooves will eat up my tires over time. I saw a post where someone wrapped electrical tape around the rollers to smooth out the contact surface, is this really necessary, or will the grooves be okay for my road tires.

Another option (which I would not prefer) would be to have separate tires for the rollers vs road use. I'd much prefer to be able to take my bike from outside to inside without changing tires.
