Getting ready to re shoe my bike and am leaning towards Heidenau K60's, but have heard some leak air pressure. Pluric just had one installed and needed to put some gunk between the rim and bead to stop the leak. The K60 looks like a great tire, however, they may have some quality issues to work out. Has anyone else experienced a problems? Yeah, yeah, I know, ride more worry less.........Okay, who wants to join me leaving Indiana to ride to Bike Week?
