    So you guys that have done this are putting in the valve stem after taping rather than putting the valve stem sealing washer against the rim and then cutting an opening in the tape after taping?

    I think the seal between the tape and the valve would be better if the valve is put through the tape and then sandwiching it with the rim.
    Put the valve in before the tape and you are just relying on the adhesive and the quality of the hole cutting to keep the air in.
    If you watch the OUTEX installation video around the 1'50" mark, the valve is put through the film so it uses compression to get the good seal.

    I know from doing the tubeless method using epoxy you obviously just seal the valve against the rim using the included rubber gasket. That works fine. But, it seems the majority of tape users cut a hole in the tape last and the sandwich the tape with the valve.

    Not at the moment. I'm wearing down a K60 TT rear before I can convert my other rear rim and am waiting for Mitas to release the E07 Dakar 21" TL before I do my other front rim. I've got all the supplies ready and waiting.

    My now tubeless rims are hanging in my basement with my more off-road tires set. I've been too busy to do much riding other than commuting as of late. But the wheels are still holding pressure after a number of months.

    I'd like to do this to my Ural rims when I need a new rear tire or have a flat.

    Do it in the safety, warmth and cleanliness of your garage/basement and not by the side of the road. Plus, a powerful compressor aids in seating the bead on a tubeless tire.

    I recently did the rear rim on my DRZ400SM using 3M 4412N. It took me half an hour from start to finish (tire was already off the rim to replace a leaking tube). That's 1/2 hour to clean and degrease the rim (mineral spirits and isopropyl alcohol), install the tape (one layer with overlap at valve hole), insert the valve, install the tire, and inflate tire/seat bead. The rear SM rim has a safety bead, so should be as safe as any other 17" tubeless wheel. It went so quickly that I did not pause to take any pictures.

    A 15' roll of 2" wide 3M 4412n tape cost $27 on Amazon. Angled metal valve stem was $5. So the entire conversion only cost a little more than replacing the tube would have. No more fighting to get the tube in straight and untwisted, nor having to worry about pinching it while installing the tire. I have enough 3M tape left over to do 2 more 17" wheels, so I could do 3 wheel conversions for less than the cost of 3 good inner tubes.

    I've always wondered about using silicone or some sort of pliable sticky 'tape' to do this to my bikes. Glad to know there's a viable option for it.

    May try this once I finish wearing out my Bonneville's rear tire and on my XR250R when it needs the tires changed.

    When I mounted my tape, I cut a hole in the tape at the end for the valve stem to seal. I cut this hole large enough that the rubber gaskets for the valvestem did not touch the tape.

    My viewpoint is the rubber valve stem gaskets are designed to seal against a hard surface and did not want an additional compressible member in the joint/sealing interface.

    I also Left the wheels overnight in my heated house and then re-rolled the tape with a wooden dowel to ensure it was adhered everywhere before mounting.

    Had any one used the tape successfully on a dr650 front wheel?

    I do not think it had a safety bead, is it an issue?

    Keep your lawsuit, tire exploding theories at bay I’m aware of the risks
    I simply want to know if it will hold air while riding the bike or not

    The 3M tape will hold air. If the DR front rim has a hole for a rim lock, you will want to plug it with something prior to taping.

    Lack of a safety bead is an issue for safety, not for sealing. You are the only one who can decide if the risk of running a non-safety bead tire without a tube is worth it.
