OEM for 8k (back tire slippery as hell in the rain - front followed the groves in road - hated both). Michelin Pilot Road for 8k. Liked um, but also like trying new stuff. Read good reviews for Metzeler Roadtec 01. Metzeler had a 'buy two get $40 gift card" deal going, so took the plunge. The rear tire is awesome. My favorite rear tire so far. Bought their "HWM" version, made for heavy bikes. The front tire is not holding up well at all. They don't sell front in "HWM" version in 19" rim. Front is moaning/groaning in turns now, and starting to re-form. Blue beast is way too heavy for it.
Probably replace with another Pilot Road, unless I read about something better.
I picked my 14 up this year with 7800 on the clock and a new/er tire on the front (Avon). The rear has OEM and now with 9800 miles and still a little life, but coming due for replacement. 8k for the Road Pilot isn't impressive at all. Was it the Road Pilot 4 GT or what? I am considering the Road Pilot 4 GT as a possible replacement as well.
