Saw an article in MCN years ago that works very well. By using a sureform file{kinda like a cheese grater} you can round off the ridge & smooth cupped tread. Put bike on center stand idiling in 2nd or 3rd gear & drag file over tread holding filewith 1 hand. Try both& it will knock it out of your hands. Be patient & rubber will be removed slowly. Stay away from the center &concentrate on rough stuff. You might think you're piling miles on the floor but most of side rubber isleft on the tire when it's changed anyhow. Not only is it quiter but by restoring roundish profile handling is much better. Works great!
