|   Homemade Rim Strip for non-tubes | DiRT
Apr 14, 2003 5:28 AM | | Stan uses a rim strip with valve. Others have tried a maxxis rim strip with their homebrew methods.
Why wouldn't wrapping the '3M brand super 33' twice around the rim, putting it up into each rim edge (where the bead sets in) work the same? I assume the two rounds of 3M tape would overlap in the center of the rim bed. Maybe someone has tried this and it failed.
I will try it the next time I seal a rim, unless someone tells me they failed to get it to work.
I'm using the homebrew method to create a notubes tubeless system. Details:
Synergy velocity rims
Hutchinson Mosquito Gold.
1 round of strapping tape + 1 round of 3M brand super 33
NO rim strip
Homebrew molding rubber solution (ETI brand, bought at Michael's Crafts for $7 w/ coupon) |

Apr 14, 2003 6:12 AM | | What you describe is a little similar to Stan's original method. The occasional problem there was that some conventional tires didn't work too well trying to adhere to the rim under extreme conditons--bead separation. One thing the rubber strip does really well is make a better seal between the rim and tire. I'm still running a couple of Sun Rhynolites with the taping method and a large Michelin hard plastic strip on top of the tape. However, I'm running UST tires on those rims which have been bulletproof. The rubber strips and Stan's new sealant are worth the money. |
| One problem--3M tape is rubber... | DiRT
Apr 14, 2003 7:44 AM | | Thanks. This is the reason I ask. The 3M super 33+ tape is a rubber like tape. By taping right to the rim edge, where the tire bead is set, I would think you could get a better seal.
The reason for doing it this way is to save weight and $$ on the more expensive rim tape.
Another thought:
How about brushing a thin strand of the latex compound onto the rim edge and letting it dry before mounting the tire (non-tubeless tire)?
Just a thought. (I'm sure all of this has been tried, probably by Stan.) |

Apr 14, 2003 8:37 AM | | No!! it has not been tried by Stan. I think you are doing a great job in trying to figure out something lighter and cheaper KEEP UP THE GOOD WORK. BTW I don't think that the Stan's is worth it. Little too much plata. |
| But that rubber tape won't lift with bead. | TNC
Apr 14, 2003 11:35 AM | | By that I mean the tape you'll use is just that--tape. It will/should stay very stuck to the rim. Although is might be better than just packing tape, it will not have the ability to lift a small amount with the bead under a severe side load, which is one of the major benefits of Stan's strips. This quality is shown on his site using a C-clamp. I just recently experienced it with a UST CrossMax XL rim running a conventional WTB Weirwolf tire. I used a Stan's rim strip for UST rims, which I kinda thought might be overkill. When I recently pulled this tire/rim apart to put on another tire for an experiment, it was evident that this strip and tire had indeed been lifting as a unit together. I could see fine debris at the bead/strip interface on the rim. Even though, I never lost air, sealant, or control. I know you can run UST tires on conventional rims even with a tape system. I did it on 6 different wheel combos. I think you're pushing it with a good many of the conventional tire and wheel combos. Get a rubber strip system--it's worth it. |
