    When I mounted this Heidenau K60 Scout all was prefect,
    ..............seated with a little extra psi
    ..............used conventional tire lube from Napa
    ..............held air weeks at a time, not needing topping off

    Now, after 1,700 miles it will not hold air overnight :huh

    The only leaks I find are at the bead.
    The plan is to unseat the tire, slap on some lube bwt the tire & rim & reinflate.

    After all this time,
    ..........was there something done at installation to cause a delayed bead leak?
    ..........has anyone had this happen?

    What gives?

    Yes...happened to me not long after I got my first Heidi front tire. It happened in cold weather first while out in the bush in Big Bend, TX.

    Was running tubeless then...happened a few times when I got back, put a tube in and no issues.

    It just started happening on the Heidi rear this month. No bubbles on the rear like the front when I soap it up to check.

    Front is a known issue, there is a thread here from a year or so ago about this. Apparently Heidi knows about it but has yet to change the mold to better fit the GS rims. That what I remember from the thread...to take that for what it's worth.

    As to my rear tire leaking...it's odd since the temp is not getting too low.
    My anecdotal evidence says it's temprature changes of 20 degrees or more that change may cause the rim/bead situation to change with temp fluctuation. Since it's happening on the rear in 90 degree weather it's not exactly temp related...it seems to be the drastic or rapid change in temps that effect the bead.

    I'll add a tube to the rear and make sure my pump is working good. Kind of a bummer because I really like the tires. Good news is you could still make it home tubeless if the tube went flat...so there is that?

    Good luck

    Good find on the link, thanks. I knew it was in here somewhere.

    For what it's worth, I'll be sticking with the Heidi rear, love the wear and grip, perfect for my needs. Will run a tube an have the tubeless capability as a back up when the tube fails (and it will).

    Going to go TKC on the front when the Heidi runs out. Had the TKC/Heidi combo for a short time and really liked it.

    Also of note on the linked thread, clean those rims, huh? A little scotch brite to make sure everthing is smooth and clean. Duly noted.

    And use for-real tire lube, like Ru-Glyde (used dish soap for may years, but the Ru-Glyde makes a world of difference)

    The buildup of rubber on the rim over time will cause this. When changing tyres the rims where the bead seats needs to be cleaned and sometimes sanded to give a good seal. I need to do this again myself, my front tyre goes down daily.

    Wish I had known this about the Heidenau K60 Scout before now........
    .............I un-mounted the tire
    .............cleaned the rim to the point of "super" clean
    .............remounted the tire with NAPA tire mounting lube
    Still it leaks at the bead :cry
    Yes, looks likes it's tube time.

    Maybe I'll try the TKC up front next, thanks for the tip!

    "Tech" makes a bead sealant, but I have seen the old tar-based Permatex sealants used to stop a bead leak. I hate to use a tube if I can avoid it.

    The last GS I saw with a bead leak had a badly damaged rim. Someone had hacked it with tire irons.

    Thanks bmwrench...:thumb

    I too hate using a tube in a tubeless tire...........
    Got myself a quart of NAPA bead sealer and applied........
    Inflated the tire to 50 psi & it seated without problem.........
    Pulled the valve stem core & let the tire sit for 3hrs without pressure, enough time for the bead sealer to cure (I hoped).....
    Inflated & found two very small leaks at the bead..........
    Maybe I can live with this............I do have a tube on hand.............

    In the future I'll be looking for a different tire so as to avoid this problem..........
    Thanks all for your input

    No shit. Can't believe how much work it is taking to get these tires to work on the R100GSPD. Thought I had it covered but found one more spot where the air is leaking so the rear is coming off yet again. What a pain in the ass. Think I'll just stick with the TKC-80s from now on.

    I had the heidinau on the front of my 92 gs, ran it for about 2 months, and then it started leaking down. It totally deflated, and broke the bead on an exit ramp. I took it back to the dealer, and the dealer replaced it with a new front tire of my choice. I 'm running a Karoo 3 up front.
    My back tire was a Heidinau also. It never leaked, and I wore it down pretty good, but it started losing chunks of rubber right at the edge where it still had pretty good tread. When I removed it, it had cracks all the way around the edges.
    I won't run them anymore. I've run TKC 80s bald, and never had any issues. I just have to remove a little tread on the paralever side for clearance.

    My bad, dynabeads got up in between the tire and wheel. Cleaned them out and the rear is holding air. Front still has a tube...

    My GS rims never held air no matter what tires I fitted, and I just got used to using tubes.

    I can't feel any difference riding the bike, the tires if anything feel cooler, and I haven't has a flat since.

    Just put a set of Scouts on my '91...

    deflating tires are not new for me... first the front would slowly leak then the rear...

    Rear (sahara) finally kept air after multiple deflates and refills over 2month period.

    Will post an update in a week on how my K60 Scouts do on my GS.

    If you want to stay tubeless, get a stick of Door eze. It's a stick of waxy lube for door latches. Even works on rusty steel wheels. Lasts as long as the tire.

    damn I had heard the Scouts were a good tire. I was going there next after my TKC's on my PD. I think I will renew with TKC's.
