    I’m not anal about much, one of the things I am anal about is air pressure in my tires.
    Moto, car, trailer, whatever….if it is between me or a loved one & the pavement I’m anal.
    So on a pre ride tire pressure check I noticed I was down about 10 PSI.

    WTF?

    I take a look & sure enough foreign object. :eek1

    So, open the tool kit get the plug repair tools & material & go to work
    [​IMG]

    Out with the foreign object, in this case a 1.5 “ screw

    Clean the hole

    Insert plug

    Trim plug

    Done - 15 minutes including picture taking time

    So, how long can these 880’s last with a plug?
    I figure I got 6-8K of tread left on them.
    Can I ride em out of tread with a plug in them?
    I don’t ride that hard & rarely see triple digit speed.
    Mostly highway speeds of 70-80. Occasional gravel.

    I've heard some people say "don't worry 'bout it, it'll do fine with the plug."

    I've heard other people say "the tire is a no go now, must replace. Very dangerous."


    Me, I'm more towards the former. If I thought I had 6-8K miles left on the tire, I would likely trim the plug on the inside of the tire and put a patch over it on the inside. OTOH if I thought I had 1Kmi left I would simply take the attitude "don't worry 'bout it, it'll do fine with the plug." In fact, this is what I've done on both cars and motos.

    But that's just me....

    Thats a lot of miles to run on a plug. I would at least have a shop pull the tire and install an umbrella plug/patch and remount the tire. Shouldnt be more than $50 if you bring the wheel in off the bike.

    You won't find a regular bike shop that will do that in the US.

    Ride it, watch it, check the pressure a lot. The worst that should happen is ya get a slow leak. I ran mine a few thousand miles before I replaced my tire.

    What Rad said.........

    You can always have the tire dismounted and patch it from the inside yourself. Done properly, it should last until the tread is gone.

    Hey, Mike! :wave

    You change your own tires, right? Like others have said, take this one off and put an "umbrella" patch on the inside and keep and eye on the pressure. It should be fine for the life of the tire. I ran a rear Tourance for ~7k miles like this with no problems.

    You can get a car tire patched at any tire place or most gas stations. You will be hard pressed to find a bike shop that will patch a motorcycle tire in the states. A small independent shop may do it.

    I plug 'em and ride. Did one today. I'd surely be happier riding a plugged tubeless tire than a patched tube.

    :dunno

    After reviewing your pics I think you should have used a word other than anal to describe yourself:lol3

    Get a Best Rest Cycle Pump or something equivalent if you don't have one already. I had a plugged hole once that would start leaking again after several hundred miles. If you have a pump with you, replugging the tire in a parking lot is hardly even an inconvenience.

    This is why if I thought I had more than a month's worth of miles left on the tire, I'm happy simply putting a flat patch over the trimmed plug on the inside. Very easy to do (don't even need to completely remove the tire) and patches are available anywhere.

    Funny, but even the way message boards have a way of "amplifying" improbable events, I never hear of any tires that are simply plugged suddenly losing air or other "catastrophic" failure on any boards I've been on.

    Hard for me to understand the paranoia about plugs.

    I had a plugged tire on my pickup explode. Probably because of loss of pressure while I was driving. It happened about 20 miles after I left the shop. For autos; no good tire shop will plug a tire. Automobile tire manufacturers definitely recommend against it.

    After plugging a tire, the GS manual recommends a reduced maximum speed (pretty slow) and tire replacement.

    Just remember that all of the control forces are transmitted through the tire/road interface.

    I agree that if you are careful, the failure is a low probability event and many people have used plugs successfully. The possibility of tire failure is, however, significantly increased. If I can eliminate a risk for a few hundred bucks, I'll do it.

    The difficult part of safety is that you don't get any extra, you just get to keep what you have.

    I ran a plugged Bridgestone Exedra on my ST1100 for 4000 miles, no problems.
    Would do it again.

    Funny you didn't notice noise or weird handling before failure.

    I would cynically attribute such overcaution to the usual liability concerns. Mainly stemming from the fact that stupid people will not notice slow loss of pressue from a failed/failing plug and will drive on it until somehing bad happens.

    Never had a problem with a patched/plugged car tire. Used a sticky string plug when I picked up a 3" drywall screw in 1000-mile-new rear Tourance. It will occasionally bleed down slowly over several days so I have got in the habit of checking pressures more often (probably as I should always be doing anyway). Changed the plug out for a newer one (original was a bit old/dry when installed) which helped. No safety worries and no probems encountered during the subsequent 6,000 miles, including some rough gravel. Expect another ~5000 miles from the tire and plan to ride on it until it is worn out.

    I had a screw in an almost new (less than 500 miles) tire. I took it to four motorcycle shops in the area. No shop would touch it. Maybe the just wanted to sell a new tire.

    It was a worn-out and overloaded with camping gear International Scout. It was noisy and handled wierd before the bad tire. I would expect that a low pressure tire would be easier to detect on a bike. I've never tried it. How low can you let the pressure get before a motorcycle handles noticable different?

    Certainly your cynicism is not misplaced.

    Some people claim they can tell the difference with just a couple of psi. I am not sufficiently attuned to achieve such a nirvanic state of one-ness with my bike that I would notice. However, I can tell immediately if one of our training bikes has a low tire (lost 10 psi or more). Several times I have had a "Hmmm... something's not quite right" feeling and subsequently found that a tire was 5-7 psi low. Front tire at that small loss is only noticeable during cornering, rear tire will feel 'funny' on the straights too, slightly vague perhaps. I am getting better at determining what is wrong.

    Twice, I have had a rear tire blowout on a tube-tire. Both times it was quite a challenge getting safely to a stop with the bike upright. With a tubed tire this should be far less of an issue unless you are so insensitive you don't notice until the last minute.

    Good replies on this thread.

    The 880 has steel in it which means the ends that are cut in the belt are like a cable that has been cut. Nasty and VERY abrasive. Do not trust the plug.

    Taking the tire off is a bitch, but if you are willin, a regular old vulcanizing patch properly applied will last you the life of the tread - especially since the breach is so small. Trust, but verify with frequent checks. (At least two a day while riding)


    Do not trust the plug.
