How to Convert Your Tires to Tubeless – Tubeless Conversion

How to Convert Your Tires to Tubeless – Tubeless Conversion

In this video, we will walk through the process
of converting a wheel to a tubeless tire system. Hello, Calvin Jones here with Park Tool Company. If you’re new to tubeless systems, we highly
recommend checking out this repair help article on tubeless standards and component compatibility. Converting from an inner tube system to a
tubeless system can be done, but there are limitations. Ideally, the tire and rim should be designated
as “tubeless ready” or “Tubeless Conversion System” in order get an acceptable bead seal at the rim. This designation may appear on the product itself. This may also appear in the information provided
by the manufacturer. However, there are no true industry wide “tubeless
ready” fit standards, and results can vary in consistency. You will need scissors,
a seal pick or small cross-tip screwdriver, tubeless valves,
tubeless rim tape, and rags for cleaning. Additional supplies are required for tire installation.
These are covered in the appropriate video. Prepare the rim by removing any inner tube
style rim strip. Clean the inside of the rim channel using a solvent that
will not leave an oily film, such as alcohol or acetone. Choose a sealing tape of an appropriate width
for the rim. If the tape is too narrow, the seal will not
be airtight. If the tape is too wide, it may interfere
with the bead seat. Begin by engaging the tape at least one spoke
hole away from the valve. Pull on the tape as you press it firmly to
the rim surface. Be sure to evenly place the tape. If the tape is poorly placed, such as in this
example, there will not be a good seal. Pass over the valve hole again so the tape
is overlapped, and cut the tape. Locate the valve hole. Use a seal pick or a small Phillips screwdriver
to punch a round hole through the tape. In this example, a knife was used to cut the hole. The tubeless valve may have trouble covering
this cut. This can result in a compromised seal. There are different styles of tubeless valves,
and they vary in length and design. Insert the valve through the tape and through
the valve hole. Be sure the fitting is properly aligned inside the rim. Install the O-ring, if any, and install the valve nut. Make sure the nut is secure. Once the rim is sealed with tape and the valve
is installed, the installation process is the same as for
any standard tubeless system. However, there are a few troubleshooting tips
specific to converted tubeless systems. Getting a good seal on a tubeless conversion
can take time, so don’t expect to ride immediately. Check the tire in a few hours and see if it
has properly sealed. If it’s leaking, add more air and continue
to spin it to move the fluid around the interior. It can take some time, even days,
for the tire to fully set up. Tire sidewalls can vary in their ability to
hold air. In this example, a non-tubeless tire was used
in a conversion. It is seeping air through the sidewalls. The sealant inside may in time help stop this
leakage. For the process of tubeless tire installation,

  1. Great video…
    I saw there Giant´s P-XC2 rim (which I have). I would like to ask what tape and valves you used for this rim… ???
    According to my discussion with Stans No Tubes company I need to use their custom rim strip RS0048. Do you know this rim strip?
    Please advice.
    Thank you

  2. I had success using a bulb syringe instead of clear plastic tube to fill tires with valve stems removed. Just pour sealant into cup and draw it out, about an ounce at a time. make sure tip will fit in stem

  3. Hi Calvin. A very useful demonstration as usual. You always make clear and concise videos. Greetings from England

  4. Are those Park Tool scissors?! How many millions of dollars are those? lol jokes. Great video. Thanks for the refresher! 🙂

  5. I have TLR ready clinchers already but what would one gain by doing this. In fact you really only have things to lose in doing this, there are so many negatives that why would someone with any common sense and foresight ever consider this. So let's consider this, it's a real bugger to get your rim setup and sealed and as he states could take days to get it working. Tires are more expensive and more difficult to carry. You have to use a messy sealant every time you need to repair a puncher or blown tire. You need a special pump with a reserve tank to repair or fill a TLR and like a car tire you need to make sure the tire is pressed to the rim when initially filling it, another big plus when you get a flat away from home.

    There are no advantages to this new marketing scheme a inner tube is much easier to carry than a new tire. A inner tube is easier to fill then a TLR. A inner tube isn't messy like a TLR that has to have sealant to work. A inner tube doesn't weigh as much as a replacement tire and liquid sealant. A inner tube fills with a normal pump and isn't going to have sealing issues when you need to replace it in the field.

    I'm sure I'm missing more of the negatives of TLR's but I think you can start to get the drift from what I've detailed.

  6. my tubeless wheels were not tubeless ready or probably not meant to be tubeless at all but i got it to seal with 3 wraps of inch wide gorilla tape, sealant, and the tube strip i put back on after the tape

  7. oh cool, yeah let me go buy a bunch of crap, then spend 2 hrs changing my tires , and then another FEW DAYS just to make sure its ready to ride. how in the hell did tubeless catch on??

  8. Thanks Seth. This was new to me. And I dont understand why someone would dislike your videos. Especially this one.

  9. About appropriate tubeless rim tape for a rim: inner width 27 mm, should the tape be 27 or 28 or … ? We don't want to buy just all of the tapes, so any suggestions?..

  10. Great video. Very helpful. I failed once with joe's no flat tubeless kit. The yellow rim tape didn't stick at all to rim the. After watching this video I went to the shop and bought some gorilla tape and then job done. The rim was properly sealed. Thanks

  11. Just how reliable are these tubeless tires ??? I've managed some fairly bomb proof clinchers and suffered a butt ton of sewups over the years so I'm a little sketchy on new tech. =^(

  12. Can this be done with Mountain bikes? Also does the width of the tape match the width on the tire like 2.25"?

  13. I don't see the advantage. Why wait days for a tire to fully cure for ready use when I could just replace a brand new tube if needed in less than 5 min.

  14. its a fuckin expensive masive huge pain in the a$$ proce$$ :))))u still have to fix it if it gets flat :))))) just get #stopaflat inner tube and done :)))

  15. The tube poppped on my Raleigh Tokul 1. Can I change the stock rim and tires to tubeless, it doesn’t say tar on it

  16. So just to be sure, a tubeless system would work with a non-TR rim and tire? Or would you need one of them TR?

  17. hello
    i want to assemble a bicycle wheel i bought hub 32 holes i bought rims 26 / 32holes but I do not know how long it should be spokes :((

  18. Hi, I got an Soft tyre hutchinson cobra (ready for tubeless as well the rim), and I have the problem that compressed air is not enough to fill the tyre so the air escape because the soft of the tyre, any tricks to solve this?

  19. Awesome guy, I still read Big Blue Book of Bicycle Repair, even though I haven't rode one for a long time, just started riding again this year, biking can get addicting and fun, if you want to learn what a bicycle is, learn and maintain it yourself, you start picking up essential tools, it's amazing Mr. Jones even explains the part in particular and numbers, he's pretty thorough very impressive..

  20. Can a clincher tire be run safely on a tubeless ready (TLR) or TCS rim? Can a clincher tire be run on a UST tubeless rim?

  21. That blue inner tube strip, isn't that already a tape in place for ready rims? I have that, should I remove it?

  22. Can i convert my not tubeless wheelset into a tubeless one? I mean i have a tubeless ready tires but the rims are not but it is double wall rims and a wide one? Is it possible?

  23. Is there a specific reason to do the tape overlap around the stem? It seams that you could get a better balance by overlapping the tape on the opposite side of the stem.

  24. The lowest part of the inner side of my rim is deep. The rim tape doesn't stretch enough to actually mate with the lowest part. Is that a big deal?? It is holding sealent and pressure, but will the tape stretch and rupture?

  25. Calvin – Question
    just got a set of WTB : Ranger tires Steel Bead .
    can i Convert to tubeless ???

    i also have another Set WTB tubeless TCS tires the Bead is SOFT !! and Can run Tubeless
    maybe internally the TCS seas Better !!!
    Mind YOU another wheelset i have EASTON EA70 XCT had MAXXIS tires and i did a RESEAL with STANS and the 2nd day the sealant was leaking out of the SIDEWALL !!! LIKE SWEATING TIRES !!!!!
    it eventually stopped SWEATING

  26. Do i need to buy the ready tubeless rims or not because my roadbike is non tubeless rim and tyre. I already buy the tubeless valve,rim tape and tyre but ididnt work ( using non tubeless rim)?

  27. Could I just tape the holes for the spokes instead o taping the hole rim? Maybe with silicon or small pieces of tape. (Tu sum up, make little patches instead of the tape)

  28. this might seem like a dumb question: but if it i get a puncture on the road, do i have to camp out there for several days as the sealant cures???

  29. That tape you're using (that you're actually applying) looks vaguely like duct tape, where you've just ripped it to the correct width while the tape is still on the roll….. Or is this just appearances ?

  30. hi guys. question from brazil here… Did you used a regular black tape on the rim, or is a special tubeless adesive tape?

  31. The fu k is this stupid poop so complicated for

    Just put flex seal inside your tire without the tube. Dont ask how its done but i said goodbye to holes in my tires forever
