    Ever since installing my new tires and Tubliss system, I've had a slow leak on the low pressure side of the rear tire. It held air fine for the duration of a ride, but would lose about half it's pressure every night until zeroing out. I gave it some time, hoping it would heal itself, but it didn't.

    Not wanting to repeat the entire installation process (as suggested by the Tubliss trouble shooting guide), I removed the valve core from the low pressure side, squirted about ten pumps of soapy water from a spray bottle into it, reinstalled the valve core, aired up the tire, and voilla! no more leak! Even two days later, it hasn't lost any pressure.

    My understanding is that if you want to use a sealant, it has to be used from the start instead of soapy water. Once the soapy water is used as part of the installation, you're married to it.

    I’ve been Running Tuubless since God was in diapers. With wonderful success.

    The valve core needs to be re-tightened after the first couple of rides. Then checked occasionally for tightness.

    Just be careful, I damaged the valve core and could not remove it as the tangs broke. Call to tubliss and they do not sell the stem, only a new liner with stem. Was able to save it with a left hand drill bit removing the core without damage to the stem.

    My tubliss system on the rear leaked around the rim to tire interface on both sides of the rim with a motoz arena hybrid.
    Apparently the motoz bead width isn't as thick as most tires, so this is a known problem.
    I fixed it by removing the valve core on the low pressure side and squeezing in some slime tire sealant, without removing the tire.
    Fixed it up good as gold.

    Interesting, mine is a Motoz tire too.

    Try it, you get some puncture protection as well.
    I see you have it sorted anyway.

    I like to add a burst of air to the tire after getting it up to pressure to clean the valve. Got in that habit working on semis with equal in the tires.
