Tech Tuesday - Make a Ghetto Tubeless Tire Inflator

Feb 28, 2012
by Richard Cunningham  
This Tech Tuesday we learn how to channel air from a fully inflated tire into a neighboring tubeless tire to help seat the bead and get to air up without the assistance of an air compressor. The device can be assembled from parts you have laying around the garage - or for about 12 bucks from off-the-shelf items purchased at your local bike shop and an auto-parts store. 'Why bother? Well, I am assuming that a few PB riders are a little short on cash and may not posses a spotless mechanical man-cave, where every cycling related tool that can be purchased, hangs over its outline on a peg-wall above a clean Formica work surface, framed by a double headed pneumatic bike stand, alphabetically indexed stackable trays of spare parts - and an air compressor. For less fortunate PB riders, the ones who must make do with the few tools they own (most of which are probably stashed in a hydration pack), I present: 'Ghetto Tech Tuesday.'

Parts list

What You'll Need:
• Two floor pump heads (LBS - 3.50 each)
• Valve (optional) (Hardware store - 3.00)
• *1/8 or 1/4 inch Tee (Auto store - 2.00)
• *1/8 or 1/4 tubing (Auto or hardware store - 1.00)
• Zip ties (Auto or hardware store - 1.00)
• Cut-down Presta valve stem (free from old tube or crappy tubeless stem)
• Floor pump (You should already have one, but you can use a mini-pump in a pinch)
• Spare wheel that holds air and hopefully has a removable valve core.
• Something sharp to cut the rubber tubing with.
*Match your tubing and Tee barbs with the size required for your pump heads.

How to Make a Ghetto Tubeless Tire Inflation Device

Most of us have an old floor pump that gave up the ghost a long time ago. If the head and hose are serviceable, cut the hose off and you are half way done. Otherwise, assemble two pump heads, one on each side of a piece of tubing between 24 and 30 inches long. Most modern pump heads use 3/8 inch OD tubing with a smallish, 3/16-inch ID (5mm). This tubing can be purchased at auto parts stores (fuel emission tube). Silca pump heads fit standard 1/4-inch ID rubber tubing.

Cut Hose
Step 1 -Measure about a foot out from one pump head and cut the tubing there. Cut a three-inch piece and set it aside. Reconnect the two pump heads with the Tee fitting. Next, slip the three-inch rubber hose onto the upright barb of the Tee.
Tip: The smallest brass Tee you will find is probably 1/4 inch, which is a tight fit on the small ID tube that fits most pump heads. You can manhandle it on the 1/4 inch barbs with some force and the assistance of a little chain lube or bodily fluid. Smaller OD plastic tees are sold at auto parts stores on the fuel emissions rack that make the job easier, but the plastic ones can be fragile.

How to assemble the Blackburn pump head.
Just in case you need to know, this is how the Blackburn AllValve pump head assembles.

Cut and install Presta valve
Step 2 -Clamp a Presta valve stem carefully in a vice or equivalent and using a fine-tooth hack saw, cut the bulb off the foot of the valve stem. Deburr the valve stem and blow out the metal chips, and then slip it into the short tube sticking out of the Tee

Step 3 -If you found a valve to fit your hose, then now is the time to install it. Cut the hose about six inches inboard from the Presta-valve Tee and install the valve.
Tip: Don't have a valve? No worries. Clamping the rubber hose with Vice-Grip pliers set just tight enough to cut off the flow of air will work fine.

Zip Tie junctions
Step 4 -Use small zip ties at each hose junction to retain the assembly. Clip the free ends with a knife or side cutters as close as possible and you are ready for your tubeless experiment.

Finished transfer tube
The finished product should look similar to this.

Mounting and Inflating a Tubeless Tire With Your Ghetto Device

The point of this inflation device is two-fold: First, to transfer as much air to the unmounted tubeless tire as possible in a steady stream, which is far better than a series of weak huffs from a floor pump. Second, to allow you to use both hands to manipulate the tire around the rim to affect a seal while air is rushing into the tire. Once the bead is seated, you can add air with the floor pump through the in-line Presta stem to seat the bead. To make this happen you'll need to remove the valve cores from both the host tire and the one that you are trying to seat. This also ensures that your transfer tube will pass the greatest volume of air. It's showtime.

Ready to rock - my Ghetto Tubeless Inflator.
This is how the transfer line looks when it is hooked up and ready to rock. The host tire is the 26er on the left, the 29er on the right is the one we will be mounting up.

remove valve cores then close in-line valve and connect hose to the host tire so you can pressurize it.
Step 1 -Remove the valve cores from both the host wheel and the one you are attempting to inflate and set them aside where they can be easily accessed. Install the pump head with the Tee closest to the host wheel (the one which will supply the compressed air) and either close the valve or pinch the hose slightly inboard of the wheel you will be working on. Make sure that the tire is mounted correctly and the wheel is horizontal, with nothing contacting the tire. (We stood our test wheel on end for photo purposes.)
Tip: It's best to have the host wheel in a bike stand or at least away from danger so you can safely deflate it without unseating the bead. Also, if there is sealant in the host tire, ensure that the wheel is upright and the valve stem is at either a 3 o'clock or a 9 o'clock position to keep the juice from passing through the transfer tube.

Hook up the floor pump to the Presta valve on the Tee and than inflate the host tire to its maximum rated pressure.
Step 2 -Slip your floor pump head on the in-line Presta valve and inflate the host tire to its maximum posted pressure (read this information on the tire's sidewall) leave the pump in position, you'll be using it to top off the tire after the bead seats.

Pumping up the host tire.
Pumping up the host tire. With the in-line valve closed as it is in this picture, the floor pump fills the host tire on the left. Opening the in-line valve inflates the tire on the right.

Open the valve and inflate the tubeless tire. Once air is flowing you are free to manipulate the bead where it has not sealed on the rim.
Step 3 -Open the valve quickly, or let loose the Vice-Grip pliers and get to the task of seating the bead immediately. Sometimes giving the wheel a little vertical shake is all it takes to seat the beads, other times you'll need to listen for where the leaking is and lift the tire slightly to get it to seat. Yes? Once the bead seats, start pumping the floor pump. It will be inflating both the host tire and the newly seated one, but that will not matter. The bead on the newly seated tire will pop into place at the same pressure (approximately 32psi). No? repeat the previous step and give 'er a go again.
Tip: If you purchase a dual-type pump head, you can use the larger volume of an automotive spare tire, which can give you a minute longer to wrestle with an unwilling tire and rim combination.

Close valve.remove pump head and install Presta valve core.
Step 4 -Clamp the tube or switch off the valve. Next, remove the pump head from the just-mounted tire and quickly screw in the valve core. Repeat this process with the host tire, inflate both tires to your riding pressure and you are good to go. Put your Ghetto Tubeless Device in your car or toolbox for a future tubeless emergency.

Topping off the tubeless tire.
Top off your tires to your riding pressure and you are done. It was fun making the Ghetto Tubeless Tire Inflator, and since then, it has kicked butt on every tire we've used it to mount. Cheers!

 Yeah I agree but CO2 is known to affect the sealing properties of stans. I only use co2 in races or if I'm in a hurry to get back to my truck

 You inflate the tire with co2 to pop the beads into place, release it then reinflate with a floor pump. Better still, just buy a damned air compressor.

 • One Co2 pump (LBS - 5.00 to 15.00 each)
• Two CO2's (LBS - 3 pack 6.00)
• Two floor pump heads (LBS - 3.50 each)
• Valve (optional) (Hardware store - 3.00)
• *1/8 or 1/4 inch Tee (Auto store - 2.00)

 i totaly see what you mean ASPOCKALIPS801.
but i see a huge benefit in having such a device.
living and for a small bike shop in Germany that at the moment has no compressor and just use a floor pump this is a huge benefit. we would not have the money to buy a CO2 cartridge for each customer nor for a compressor and because we are in Germany everyone generally has a full set (4) car wheels, due to the changing from summer to winter tires and back.
the price for one tire would be around 12.00 using a CO2 pump and around 10.00 using the self made pump with limitless uses (excluding: valve, zip ties, pump and host wheel)
and maybe its just me but i enjoy working on such small projects from time to time

 Best way I've found which is easy and free is go to a gas station, they have free air there usually (or it will cost a dollar) and use their air compressor! you can just take out the valve core or buy a presta-schraeder adapter. For stubborn tires it also helps to use a tube in the tire to get one side of the tire seated and press the rim tape down, then take out the tube and try the compressor again.
  • 1 0
 Lotta good points here, but telling people not to be cheap and to buy an air compressor is not one. I can't buy an air compressor. I don't have the money or the place to hook it up in my apartment since they are as loud as a 2 stroke moto. Co2 is a valid idea. So is using a car tire since it has plenty of volume, even it is is only about 30psi. Plus Macguiver is awesome because he didn't need Co2 Maybe someday I'll move out west where there are lots of goat skulls to make tubeless worth the trouble.

 Just to review:

Cost of materials for Richard Cunningham's "poor man's portable air tank:" about $20
Cost of actual portable air tank that will work every time: about $30
Not being "that" guy at races when you roll up with this contraption that never works quite right: priceless

 @ mnorris - Easy as bro
Firstly, you need a plastic bag. You can usually pick these up for free from your own kitchen. Unfortunately I do not have a photo to attach.

Next you need a straw, or several depending on how far away from you your 'ghetto camelback' you will be.
I have found McDonalds straws hold the best structure and provide more fluids than bendy straws, however bendy straws can sometimes be directed more towards your mouth.

Bluetack or bubblegum optional for on and off valve.

And Lastly, a sturdy rubber band to hold the bag closed and conceal your precious H2O.
For anyone who has a little bit of money, it is well worth while getting a ziplock bag for this. They can be sturdier, however you are usually limited to the amount of water you can have in it. I measured the capacity and it's the same amount as a ham and cheese sandwich, but for your new 'ghetto camelback' you will be using water instead of sandwiches

 Team robot...You still need to get air into the tank as it doesn't compress it itself....Making it completely useless.
  • 4 8
flag TEAM-ROBOT (Feb 28, 2012 at 13:29) (Below Threshold)
 That's a tough one...let me think about it. Oh, that's right, you could ask one of your friends who has an air compressor, at anytime, and then you have compressed air available in your tank forever until you use it. And you can fill up about 100 tubes with that air. But I assumed you had friends... assuming you don't, you could always fill it up at a gas station, as in your earlier suggestion.
  • 1 0
 TEAM-ROBOT the total of this method is 14.00 excluding the pump and the spare wheel. guessing however that you will have a spare old valve somewhere from an old tube and zip ties that brings the cost down to around 10.00 this means you saved at least 18.00. this is probably enough to get a pair of new grips.
  • 1 0
 Plus team, if you are going to borrow your friend's compressor, don't waste $30 on a tank. Just use his compressor for your tyres.
  • 2 0
 I'm happy with TEAM ROBOT'S suggestion. Currently I use CO2 but it encourages me to be mean about the whole process. The tank offers another cheap alternative if I were to increase the frequency of reseating tyres, particularly as a once a year trip to the gas station to fill up an air tank is far more viable than rolling up with Stans sealant, a tyre and wheel, and doing the whole spinny shakey thing in their forecort. I'd get funny looks and I don't like that, I'm British after all. RC's suggestion is handy too, particularly if you're a small German bike shop doing lots of this for customers. For me, it's in the realm of too much darn work for something a CO2 cartridge bought for 70p off ebay does.

 It was interesting at least. Basically a ghetto air compressor that does what he aimed for, getting a steady stream of high cfm air flow to seat the bead, for use when a floor pump's irregular air flow fails.

 Hey that's my idea - I made this with out the pump attachment - so just two pump chucks and a valve inbetween Can be used for pumping up flat tyres from a car tyre - use it all the time Because of the volume difference the car tyre only drops 1psi - and you get a nice 30PSI in your bike If you want more PSI go look for truck tyres, called it the Air Thief....

 Awesome work from the mind of RC. Lots of the issues with tubeless surround getting things to seat, largely as a result of crap pumps and weak airflow being insufficient to pop the tyre properly onto the rim. This makes sense, is simple and once done, hardly a pain in the ass to use. It beats using gas canisters or traipsing down to your nearest garage to use their compressor.

 Hahaha, interesting kludge. I totally respect the ingenuity and resourcefulness here. Having said that, seriously, if you only need an air compressor for inflating bike tires, you can find some pretty small compressors for pretty low costs. Keep you eyes open for sales, I bet you can find some that will do the job for the same price as some of the higher-quality floor pumps.

 Gas station ones don't always work for me. I went to three gas stations and they all sucked because they don't work on a pressurized cylinder, they just pump air as it goes so you don't get the initial fast blast. Co2 cartridges work best. Exo Minions are finicky and need the instant blast.

 Never had a problem pumping up tubeless tires with a standard floor pump. Just need a decent pump, and some fast twitch muscle fibers for the first 5 seconds. But, great go-at-it for coming up with a rather creative solution.
  • 1 1
 I've had some bad luck with "standard" floor pumps, wishing for an air compressor and ending up stopping by the LBS to get some assistance. I wonder what your technique looks like. Fast short pumps, aiming for a rate of 120 pumps a min for that 5 seconds?

On the other hand, I've discovered that a Topeak Joe Blow Mtn floor pump has luck seating beads, but it's one of those mtn bike specific ones with a larger volume barrel. It's not rated for high pressures that road tires need, but w/e.
  • 2 1
 I have Stan's ZTR Flow rims and use Kenda tires. They pump up and seat in the rim using just the floor pump. There's just no reason to go through all that. Tubeless are not that difficult to get the bead seated in the rim. I honestly don't think tubeless is any more difficult than using tubes. This article would scare me off I think if I hadn't used tubeless. Don't let this scare you off of tubeless. Just get Stan's rims and it's simple... conversions take a little more TLC, but they're still not that tough. I've been running tubeless for 3 years now and wouldn't go back for anything!

 Well yeah it's that easy when you have Stan's rims.

 going tubeless is incredibly simple if you have an air compressor, and if you dont then go to a gas station and pay 1 dollar to get it filled. its also a lot better, i have never flatted with stans tubeless. but it is a cool idea, definitely worth posting. it would be nice to see more innovations like this.

  • 2 0
 I would have agree, a compressor also has other uses. even better, get an oil less compressor and use in to paint your bike.

Adding soapy water to the sidewall/bead area helps, it acts as a "lubricant". I'm almost certain that normal soap is non reactive with sealant, so no worries there.
  • 1 0
 In my experience, soapy water does help get the tyre up, but any residual amount also acts as a lubricant to get it off - tyres rolling off rims in corner. Got to be careful how much lubricant to use ;+)

 with a decent wheelset like stan or Sun Ringle Black Flag Pro 29er you'll mount anything tubeless with a floor pump. it's all about the rim shape and tubeless = no more pinchflat

 Ok guy we have been using a much simpler and less complicated way that achieves the same result. We use an old fire extinguisher (get one from your local fire safety retailers and make sure that it is empty!). we then filled it up with compressed air, go to a service station if you don't own one. we then cut a length of hose and fitted a hose clamp from the end of the hose to the fire extinguisher. We then got a piece of pipe to adapt the hose so it would fit tightly around a presta valve. To inflate we would take the valve core out, fit the hose over the remaining part of the valve and inflated. The high pressure and instantaniousness of it will quickly inflate the tire enought that it will seat itself on the rim, job done!

Hope that this may be a simplier and less complicated way than PinkBike have suggested.

 Proper tubeless systems have their drawbacks also, like weight and availability of UST versions of popular tyres. For instance there is no UST Minion in 1ply and many versions of lightweight XC tyres (like Nobby Nic) weigh much more in UST - for NN it is 2.4" 560g vs 820g -> no thanks. Once sealed with reasonable amount of sealant ghetto is as good as a proper UST.

Then rims: proper UST rims available on aftermarket are bad mmkay? You can only get narrow Mavics making your lightweight tyres wobbly and easy to tear off the rim. They also cost a lot. All this UST drilling keeping clean inner wall for the sake of not using something as simple as a rim stripe with adhesive? I was believing otherwise but after 2 years on proper full-on UST setup rims+tyres I came to a conclusion that it is not worth the money.

 Cool thing I found with UST is that I can run light tyres (like mentioned 1ply minions) and so far my skills go - I can pound the bike hard into anything I want, rocks, roots etc. without having this thought in the back of my head - have I punctured after that hit? I mean if you get too light (like NNs) you are going to screw the thin walls if you try to ride them like DH tyres. I rode my Nomad on 1ply HRollers WCup track in Hafjell > no probs (with the tyres, skills sucked). I am just too slow to screw them (but having said that - not the slowest man on the mountain Smile )
