1427.0. "Specialized K4 failures" by BLKWDO::HUFFAKER () Sun Feb 18 1990 19:36

    I have been experiencing problems with my Specialized touring II k4
    tires.  The mode of failure is a big chunk out of the tread (1/4 to
    3/8" diameter) right down to the kevlar belt.  I have had this now on
    3 relatively medium mileage tires (500-1000 miles, very little tire
    wear visible).  I sent cut out sections to Specialized
     with a letter and received replacement tires back (with no attached 
    note, just new tires).  Now I have the same failure in one of the
    replacement tires.  I noted that when I sectioned out the failures
    the tread was not attached to the kevlar belt even an inch from the
    chunk.  I believe I am having delamination failures.  I know that a few
    years back this was a problem but that it was "fixed".  Anyone else
    experiencing any problems??
