bought a new ultra and just read the info on dunlop tires going flat. replaced the dunlops w/ metzlers on the old r/k. does anyone make a replacement that is the same size as the new dunlops that won't affect the abs on the new bikes? where can i find a spec sheet for other manuf. tires that will get me close to the oem tires. there doesn't seem to be anything close out there w/o replacing wheel sizes to get to the proper height. thanks.
