    Sticky stuff being forced out from the bead the tire wall?

    New tire install and about 300 miles in I notice this sticky substance in different areas of the front rim. I am assuming some lube from the install, but I have not encountered this before. Should I be worried?
    Looks like centrifugal forces flinging it out across the tire wall.

    I would be concerned because the sticky stuff is designed to help get the tyre on the rim and to seal it.   If it remains a liquid,  it COULD cause the tyre to rotate on the rim.  In the olden days we would use rim locks to prevent this,  but with modern tubeless tyres they are supposed to be tighter fit. The runs in your photo show it has been very much a liquid state.

    Thank you for your reply. I am going back to the installer, I think way too much lube used. It is still coming out on the same rim side several rides later.
