if it clears you are golden.... with the measurements youve given it sound like youll still have some clearance room... you may not be able to fit cyclocross tires or anything too burly, but you'll be all good with an average road tire. there isnt any give when you are bolted in... so dontcha worry about that. just make sure you clear your down tube.... and that you are comfortable with the foot play. sounds to me like you are ready for new wheels.
