Just a mention for Goldwing tires. I just had second set of Shinko 777 tires installed on my 2012 GL1800 Wing. Set I am removing almost 18000 miles. A little cupping on both sides of the rear tire and a little cupping on front. These are the longest lasting tires I have ever experienced, quiet and great handling dry and wet. $220 or so shipped for a pair. Not bad.
