Replying to skating?

I mean rollerblades, not skateboards when i say skating. I have always iceskated and skated so i can do it so i thought that maybe it would help my rail skills in the winter if i started doing it in this summer. I have so old shitty rollerblades i use since i have no money for new ones. One thing i notice about them is they have rubber wheels. would this affect grinding the rails i use in the winter at home? it looks like they wouldnt slide too good...
