I looked into going with Metzlers because of prior experience with them. (I put 15K on a rear on a Road King with a Metzler tire.) However, I measured the width on a Metzler and compared to an Avon and the 300 Metzler is wider than the Avon and with me having only 3/16" from the sidewall to belt now, I suspect the Metzler will definitely rub. There is mention of this in another post in ref to tires on this site.
