Ran these tires @39 psi on a 2013 BMW R1200GSA. After a 2000 mile trip experienced a loud buzzing noise from the front tire. The tire has 8/32" of tread on the outside and 2/32 cupping off center.
Took the bike to my BMW dealer and they say, "this is what they have seen with this tire"!
This will be the third Lasertec tire I have bought, total miles on three is 42,000 in twenty years. Never a slip or deviation, always ready to go and no flats. Thank you German engineering at Metzeler and M.S.S for the Sweet Deal too!
I have these tires on a Bonneville T100. I've gotten 9,000 miles from the rear and will replace it within the next 500 miles. This is a 500 pound bike and I only one up ride but I do take trips with camping and other gear. I'm very pleased with the tire and got 9000 miles out of the original Metzler too. The front still has plenty of tread and will probably go 11-12,000 miles.
I've had the Z6's on my FJR for almost two months - have put 4,500 miles on them. (3,300 mile road trip). They are rock solid! They hold true in fast sweepers and in 10 MPH hairpins. Very stable on wet roads and in heavy rain - great braking traction. They are quiet on the road. No cupping on front tire. They seem to be wearing very well. I would expect 10,000 to 12,000 miles out of them.
