Yeah, I'll lurk on this subject too. Just returned from Texas hill country. I hauled FJR there to preserve my new Storm as we were riding a couple of days in the hill country, and then into Mexico. Easily 80% of the sipe was gone after 1100 miles in Texas Hill Country - 42 psi rear. I am past sick of this with all the "new and improved" tires.
I loaded up and returned home while all my friends rode their "low tech" mounts over the border. Yes, I could have bought another tire, but since the one dealer in the area did not want to mount a Metz 880, I decided to let it all go, and just waved bye to my buds going over the border.
Think I will take my 1978 air cooled, chain drive, points ignition, GS 1000 Suzuki next time. CC
