    Now that my rims are spotless, I'm ready to put the first layer of sealer on. In order to run tires tubeless, you must ensure that your rims have a safety bead on them. See photo below. View attachment 34328

    Pencil is pointing at safety bead. Also note that you must tape the hole in the end of the valve stem to keep it free of sealant. (Blue painters Tape)

    I am using GE Aluminum/Metal Silicone II. The only place I found this is at Ace Hardware; Home Depot and Lowes does not carry it.

    Note how the spokes are recessed into the nipple on my rim. The recess is at least an eighth inch deep, which helps because it will be easier to force to silicone into this to create an airtight seal. I used latex gloves and forced the silicone into each nipple. See photo below.

    When completed it should look like this. I took a while, I have to do this to 4 wheels. Now I'll let it sit for at least 24 hours and then put a layer that covers the nipple completely. Next post to follow.

    I have thought of this but does it actually work?

    Others have tried it and they claimed it worked for thousands of miles. I believe there's a company in CA that also does this for about $75 per wheel. I'm pretty confidant that it will be successful, I just have to take my time, don't rush it and do a thorough job.

    Seems like sanding the rim where the sealant would go would be important.

    no reason it shouldn't work for a supermoto. wire wheels on cars (think silly little mexican "Daytons") are sealed in a similar manner.

    Don't see it working at low PSI trail duty though. even with the safety beads, the tire would likely still burp air or peel the bead off.
