Are any of you hoodlums having trouble with K60's not sealing against the rim. I have had a slight leak on my front K60 since install 12000km ago. It wasn't bothering me because I was always close to compressed air. It is losing a few pounds of pressure over a week or so. I submerged it in a tub of water and it has fine bubble lines coming from half a dozen places around the rim/bead interface on both sides of the wheel. I de-pressured it and popped the bead at one of the spots and could not see any irregularities. both the rim and tire bead are clean and smooth. ::010::
