190-55 will have the potential for rubbing on the underwing if your chain is fresh. 180-55 works great. Zero problems related to using this size tire. Run it at the track, on the street, whatever. It does look skinnier though, so if that's important to you, then you might want to stay away.

What tire do you use, if I may ask?
Both the Bridgestone 014 and the 002's for the 180 series . The 002's of the 190-55 series rub the bellywing a lil.
