    Be Aware- Pilot Road 3

    I mounted a set of Pilot Road 3s on a friend's '08 K1200GT the other day. As part of the mounting, I always spray some Windex around the bead, after the tire is seated, to look for any slow leaks. The rims had been carefully cleaned and checked for nicks. To my suprise, there were numerous leaks!

    Upon further inspection, after breaking the bead, it was noted that the Pilot Road 3s have the normal 1/4" "hairs" on the tread, but they also have two rows of "hairs" right next to the bead. When the tire is mounted several of these "hairs" get folded over and caught between the tire bead and the rim resulting in numerous slow leaks.

    After cutting off the "hairs" with a pair of wire cutters (leaving less than 1/16") and reseating the bead, the result was no leaks.

    I would suggest that BEFORE you have anyone mount PR3s, you ask them to cut the "hairs" around the bead or do it yourself. Having to add air to your tires every few days would really suck!

    Good advice, Lee! It is not a bad idea to inspect all tires in this area before mounting them. I had a Pirelli Diablo with the same issue.

    I've just done some sloppy math and calculated I've lost 600PSI from my rear tire to date.
    Compressor juice alone is not insignificant.

    I just today broke the beads and cut off the short hairs to which you referred using needle nose pliers and small scissors.

    Thank-you very much for this information!
    I would have appreciated it even more 18 months ago but ...

    Funny the front never had this issue.

    Great timing. I have a pair in my garage to mount up. Thanks.
    I used to post here, but now I don't.

    Hi Lee,

    I'm on my 3rd PR3 rear tire now, (and a lot of PR2's before these) and have never seen this. Sounds like some mold-flash that wasn't properly cleaned up during the tire manufacturing. If I had this and had bought the tire locally I would ask for a replacement. If ordered via mail-order, then I guess your solution is the more expeditious one.

    I'll have to watch for this when mounting PR3's in the future..

    Interesting - I do not doubt that the issue occurred, but I've mounted up 3-4 sets and haven't seen the issue. As another stated, somehow those missed a step in manufacturing.

    But a great pre-mount check step.
