Howdy folks, I have a Sirrus with Forte Gotham tires on it. They are slightly knobby hybrid tires (I have a sand-patch phobia). My bike was recently tuned and the tires are brand new, but the season is winding down. I have a fluid trainer that I've used in the past, only with standard road tires. Question is, could I use the trainer with the tires I have? My assumption is I will wear down the tread, but is like to get through some moderate-light off-season biking. Could anyone speak to this? Thanks! Naltimar
