    OK, I just got screwed for the first time. (not what you're thinking.)

    Took a 3" wood screw in the front tire.....never done a plug before.

    Do you guys use the GSA plugs that came in the tool kit? Or is there something else you can recommend?

    Any special techniques?

    My local BMW dealer held an evening tire repair clinic, which I found very helpful. They demonstrated with the BMW kit on a few bikes, drilling holes and having us repair them under supervision.
    A few tips:
    Really get at it and bore the crap out of the hole with the hand tool. You want to scruff the hell out of the hole...more the better. "If you don't break a sweat, it ain't enough"!
    Lube the hole with the glue, then lube the plug tip when it's mounted on the hand tool thing. Lube is good:thumbup
    Important: when inserting the plug push hard STRAIGHT in, then pull back STRAIGHT out in one movement. DO NOT twist the hand tool! Helge Pedersen demonstarted this in his DVD, Globe Trotters, and messed up the patch because he was twisting the damn thing.
    Lastly: do not trim the patch flush to the tire. Leave a small section protruding after you trim with the supplied razor.

    Sorry, but get a new tire as soon as possible. These patches are meant for emergencies only according to BMW (and the tire sales dept:deal).

    A string plug repair will last the life of the tire. Absolutely no need to replace the tire.

    I have had to plug every tire (save the recently installed rear) I have had on my GS (2001 model...5 sets of tires including OE T66s). I have had only one plug leak after several 1000 miles. So, I am a believer that plugs, properly installed work. I heat the tire in the sun before beginning the repair. I caution against being too agressive with the hole file...just enough to expose new, clean rubber. File the hole in the same orientation as the object removed.

    Careful not to sever any steel or fabric cords.

    Use plenty of glue and allow the plug to cure before riding...30 minutes in the hot sun is about right.

    I overinflate to 50 PSI during the plug cure if I am near compressed air.

    Plugging a rear tire is ok in my book, plugging a front is a no-no. Too much risk.

    +1 on that.

    Had 3 nails in my tire last year. Used a $8 string plug kit from Autozone, and never looked back. The tire wore out before the plug let go. If the plug lets go-- put another one in. Simple.

    Just make sure you don't go crazy with the bore/rough tool and make the hole too big.

    String plugs...the only way to go. A few years ago I installed a new rear tire and it collected a nail less than a mile after installation. Plugged it with a string and rode it for 9000 miles.

    ...and what are the risks? Please do tell.


    My experience with string plugs on a bike or a car, front or rear, is that they work.

    Well, I guess BMW is only trying to sell tires (besides their plugging kit)! Who knew?:huh

    If it holds air for the first few minutes it should hold it for the life of the tire. Plug it and ride it.

    Glad to hear the good news about string plugs. Had the pleasure of using my first one yesterday. I am hoping it will let me go the next few thousand miles on my Tourances.

    I tried to plug a rather big hole, ¼” metal pin I drove over. The plug worked flawlessly for about 100 miles and then failed, on the freeway:eek1. It appeared a cord broke inside the tire and no the sidewall was deformed and the plug was ejected.
    <o:p> </o:p>
    So what did I do; plug it again and drive home 30 miles real easy. Next day got a new tire.

    Just be careful they can fail!:deal

    Did you use a string plug or a rubber plug?
    1/4" is huge, most punctures are nails or screws
    although my wife got a flat on her car that was caused by a
    wrench that poked a 1" hole!!:huh
