I have Metz M880's front and rear. About 11,000 on the rear and about 5,000 on the front. The rear has good tread left and the cupping is visibly and audibly noticeable. The front cupping is still superficial. I do a lot of highway miles and it seems to be that 10,000 to 15,000 is the best we can hope for from the three major brands spoken of here. I should note that I have been averaging 10,000 miles a riding season, so in terms of " how long " they last........well I wish it were longer.I have a 2001 1800A I just aquired, and I was thinking about the Metzlers m880 , I ran those on my kawasaki vulcan nomad 1500, was gonna check them out for the wing, so whatdo yaou think about this I have had no problem with them on my old bike ,
Do a search at gl1800 riders and I think you will change your mind about the Shinko tires.Dunlops to me have always been "loud". They tend to cup and then when you go through the curves they roar at you. I am currently running the E3s because they came on the bike. I have a friend that is very happy with the "stones". I think, due to the good luck I have had with them on my Concours, I will try the Shinko 757s.
Larry, I never thought you'd ask, but since you did..............What kind of oil does everyone use?
