Disclaimer: The following worked for me. I cannot guarantee that it will yield similar results for other rim/tire combos.
Some folks were curious how I converted my Rolling Darryls and Nates to a tubeless setup. This is a brief rundown of the process. No videos and even the pictures are not of the best quality! Sorry!!
I have been running tubeless since April with great success. During this time I was using Gorilla Tape to seal the rims. It worked fine, although it has a tendency to absorb some of the sealant. It is also a very tenacious tape and is a PITA to try a and remove. I had a small issue in November when my rear tire ran dry of the sealant and started to leak air. I broke down the setup but had no Gorilla Tape on hand so I tried a new tape - just for poops and giggles - to see if it would work!! Surprisingly, it worked incredibly well. The new tape is the 3M Safety Stripe. It is a PVC tape that is stretchy (unlike the Gorilla) so it can be worked into all the nooks and crannies of the rims. Plus it seals upon itself quite good. I used it for a few weeks before I broke it all down again. There was no apparent damage from the sealant, no absorption - all was the same as the day I put it in! Short term test was a success!!
Fast forward to this weekend when I decided that it was time to stud the Nates!! I figured that if I am going to break down the tires, I might as well redo the tape and all. So here we go . . .
What I used:
3M tekk Safety Stripe Tale - purchased from Princess Auto.
Stan's NoTubes Sealant - purchased at Fun 'n ' Fast
Stan's NoTubes valves - purchased at Fun 'n ' Fast
Air compressor - the bigger the better
Hopbot IPA (optional) - purchased at the NLC store
|The stuff that you need!!|
|The optional stuff!!|
1) Remove the wheel from the bike (d'uh!)
2) Remove the tire and tube if applicable (double d'uh!)
3) I had to deal with the hassle of removing the existing Gorilla Tape strip and associated gobs of adhesive left behind (ugh!)
4) If necessary, trim your rim tape if it necessary. There needs to be enough of the rim's shoulder exposed so that the tape has something to stick to. (See second image below!)

5) Run a single strip of 3M tape all the way around. Make sure that the tape spans both the rim tape and the rim. This is crucial in order to get a good seal!! Ensure that there is a bit of overlap between the ends of the tape as well!
|Running the first strip. Notice that sealing tape spans both the rim tape and the bare rim. (See step 4 above)|
6) Apply good pressure to the tape to make sure that it stretches and gets worked onto the rim and the rim tape!!
|Rubbing the tape hard enough to create heat seems to aid with it sticking and conforming to the required shape!|
7) Apply a second layer of tape as per the first!! Make sure that you have a tight seal where the two layers overlap down the centre line of the rim! This is one of the areas where leaking can happen.
|Applying the second layer.|
8) Poke a hole through the tape for the valve.
9) Reinstall the tire AND the tube*. Yes, the tube!! Inflate to a high pressure - 20 psi or so. Let sit for a while.
*This is a pretty critical function of the whole procedure. By reinstalling the tire and tube and reinflating to a high pressure, you are getting the tire beads to set nicely.

|Inflate that sucker till it feels like a road tire - almost!!|
10) After letting the tire sit for a while (15 minutes or so should be fine) deflate the tire completely and break ONLY ONE SIDE OF THE TIRE BEAD to remove the tube!! By doing this, you are leaving the tire with one bead nicely set and that is half the battle!! If the other bead breaks while removing the tube, reinflate and let sit for a bit longer.
11) Install the Stans NoTubes presta valve in the rim. Hand tight should be fine for now.
12) Lay the wheel, loose bead down, on a 5 gal bucket or other such device that will support the centre of wheel. This allows gravity to help!! The loose bead will droop towards the rim and aid in the initial sealing - hopefully!!
|That is only muddy ice water in the bucket!!! Note the use of schraeder adapter for the valve.|
13) Inflate the tire with the compressor. Hopefully the bead will be snug enough to hold air immediately. If so, continue to inflate to a good pressure - again, 20 psi is nice!!
The higher the capacity of the compressor, the better your chances of getting a seal right away as it forces more air into the tire quickly.
14) Both beads should now be set! Remove the valve core (not the whole stem) and let the tire deflate.
15) Rig up a way to get the Stan's sealant into the tire through the valve stem. There are any numbers of way to do this. (View image below to see how I did it)

17) Reinstall the valve core and reinflate the tire to a nice high pressure - 20 psi or so.
18) Perform the Stan's Dance!! Spin and bounce the tire off the floor. This helps slosh the sealant around and aids in its finding any leaks to seal!
|Safety Dance!! Best to wear gloves when doing the Stan's Dance with a DIY studded tire!!|
19) It is a good idea to get out for a ride right away to help with the sealing process. I urge you to take a pump with you - just in case!!
20) Monitor the tire to see how well it retains air.
So, there you have it!! Hopefully I have not omitted anything of importance!! If so, there is a plethora of videos and such on the Interwebs showing exactly how to do this! Some even have videos!! LOL!
Thanks for dropping by!!
