    Filling Tubeless Tires - Do you use a Syringe?

    I recently converted to Stan's and everything is going great. The area around the value stem on the front took a while to seal, but since then they've been great.

    I also live in a hot area (Central Texas) and summer is coming up...I'm guessing my Stan's will dry out at some point and I'll need to add more.

    I plan on using a syringe (hypodermic needle) to inject through the tire so I don't have to open it up just to add more Stan's.
    Is anyone else doing this? If so, what size (gauge) syringe are you using? I'm able to find a 14 gauge needle but nothing larger. Will this be large enough for the micro-beads to fit through?

    Thanks,
    -Millbarge

    That sounds like a bad idea. You don't really want to introduce a puncture (even though it would seal) into your tire. Remove the valve core and add sealant through the valve stem using this: 2oz Tire Sealant Injector

    Or, just pop a few inches of one side of the tire bead on the opposite end of the wheel from the valve core, add sealant and air up again.

    I'm new to the whole Tubeless Setup and was worried that bead would come unseated when releasing all of the air. Will the bead stay when deflated?
    It's not a big hassle to get it seated and sealed again, but it would turn a 30-second refill into a 10-20 minute reseat/reseal/refill procedure that I would like to avoid.

    The bead will seal up rather quickly if you break one side of it to add sealant. Especially if you go for a ride right after you add some sealant or spin the wheel around for a minute or two in the work stand. Most of the shake and dance, lay the wheel flat routine on initial set up that takes 10-20 minutes+ is to seal the sidewalls of tires - especially when converting non-tubeless tires to tubeless. If you add sealant through the valve stem by removing the core and using either the injector NoTubes sells or your own ghetto version - it takes about as long as popping one side of the bead does by the time you remove the core, screw the injector on the valve stem, inject a couple of ounces, put the core back in, air up and clean up the injector. No matter which way you do it, I guarantee you it cannot be done in 30 seconds. Allow yourself a few minutes no matter which method you choose.

    One reason I like to pop the bead every now and then to add sealant is to check for boogers. This is what I found recently when adding sealant....

    <a href="http://www.flickr.com/photos/7166535@N05/6613124545/" title="A pair of Goobers! by BBcamerata, on Flickr"><img src="http://farm8.staticflickr.com/7141/6613124545_d1ac3e242c.jpg" width="500" height="384" alt="A pair of Goobers!"></a>

    Popping the bead allows you to pick your tire's nose and get the big boogers out of there.

    What stems do you have? That seems weird considering I've got it and have used it without issue with both Stan's and AC valve stems.

    I've personally never used a syringe but I know some people do. Personally I just pop the tire off one side and have a look from time to time (maybe scrape some boogers out - its kinda cool to see how many flats have been sealed by the stuff). I've found the stuff seems to be good for a couple of months (I've only ever used Stans). I'll add a scoop here or there. I know a lot stuff is said about complexity of tubeless etc but I have to admit that after you do it a couple times it very easy to do and very low maintenance.

    Also use the injector.ApparentlyI lack the skill it takes to pour it in the tire without creating a friggin mess everywhere.
    On longer rides I just fill the syringe, fold the hose over and secure with a rubber band. Throw it in my pack. Havent had any issues as of yet. Course I havent had to use it on the trail either. Well except for the time I didnt have it and then used my buddies bike to ride home and get it. Figures!

    Why do you need the injector on the trail?

    I was going lot ask the same thing about needing the injector on the trail? I've only flatted a couple a couple times on the trail since going tubeless. One was a 1/2inch hole which no sealant was ever going to seal. The other was a complete shredding of a sidewall. I just pop a tube in and carry on. I live in dry cactusy terrain and used to get flats almost every 2nd ride. Tubeless with sealant has virtually eliminated flats

    What do others do when they get flats?

    I tried the valve stem injection method once with a syringe and clear tubing from the hardware store. It wasn't as effective as simply breaking the bead and pouring in the Stan's. I hold the bead in and pour the Stan's on the rim strip and it flows down inside the tire. A lot less messy for me.
    Authorities speculate that speed may have been a factor. They are also holding gravity and inertia for questioning.

    I buy these from Amazon for around a buck apiece (60 ml is ~2oz):
    Amazon.com: SPECIAL Pack of 5 -IRRIGATION SYRINGE PISTON 4262 60CC DYNAREX CORP.: Health & Personal Care

    They are also great for filling with various types of grease for maintenance work. They have caps, so you can fill them and leave on a shelf.

    For tire sealant I take out the valve core and use a short piece of vinyl tubing that fits snugly over the valve stem. I don't even have to use the plunger since the stuff runs right in. I chase it all with a spray of water to keep the valve from getting gummed up.

    Caveats: I use schrader valves and Caffelatex with fibers added.

    I do carry a syringe on the trail. I got tired of dumping sealant out when I lacerated a sidewall. The syringes come with caps, so you can siphon out the sealant for use later, or for immediate reuse if you can repair the tire.

    Last time I had a flat on the trail I thought I would "just throw in a tube". When I opened it up the tire looked like an inside-out pincushion, with scads of cactus needles and a few very large thorns. No chance of a tube working.

    If you inject through the stem press the tire to force out some air, then hook up the syringe, then let go of the tire. Just forcing the liquid in will build pressure and you will get blowback when you remove the syringe. Also rotate the tire so that the stem is off bottom dead center by 45 degrees or so.

    Go to your local pet/feed store (think rancher) and they'll have syringes for about a $1. No need to spend $10 for a Notubes brand.

    Put the wheel in a bike stand, then break the bead at the bottom with a tire lever, fill with the stans scoop and reseal - done. Super easy.

    Yes pick out any boogers.
    I have been tubeless for a couple of years and don't ever carry sealant with me. Just bring a tube - for an emergency. Done

    I use an old medicine syringe. Works great. I donít carry Stans on the trail, but I do have it back in my truck. Iíve had slow leaks on the trail that I was able to add sealant to at the truck, then continue to ride. Usually happens when I havenít refreshed the sealant for awhile.

    Yep, I get mine at Tractor Supply Center in the horse/pet section. They have all kinds of sizes and are cheap. They also come in handy for fork fluid changes.

    It's not too bad - just 4 ounces of liquid.

    If it keeps me from pushing my bike - I'm all for it.

    I use a 2oz syringe with the needle removed. I unscrew the valve core, put the tip of the syringe in, and inject slowly. The more of the tip that fits in the valve, the cleaner the injection. Then just re-install the valve core, inflate, shake, and go. Works perfectly for me.

    I've used the stans injector, works great.
    Or you can buy a 3 pack of plastic squirt bottles from harbor freight and a piece of clear tubing from hardware store for about $0.25 & that works just as well.
    Or break the bead, pull out the stans booger, & refill.

    Trying to use a syringe & going "through" the tire probably won't work cuz you'll plug up the syringe.

    I have found that pulling back the bead and checking sealant levels once a month is the best way to eliminate problems. You can top it off without overfilling because you know how big the puddle of sealant should be. Even identical tires can dry out at wildly different rates. Still carry a tube of course.

    True ust tires are a different matter... I don't run them but I would expect that sealant would last the life of the tire. Still carry a tube, of course.

    Bill, are you having to clean all the dried sealant off the tire bead and rim bead seat before you put the bead back over (which sounds like a PITA) or will things seal back up pretty easily w/o cleaning the interface? I like the idea of checking regularly versus my usual method of waiting until I get a puncture that won't seal, and then realizing I'm dry. Thx,
    - Joe

    I don't try to clean anything off anything, just slip it back on. I think any sealant present on the bead or rim edge is a bonus for a quick reseal. Wipe off any excess after it's aired up again. Call me Easy.

    A foot of clear tubing from Home Depot or Ace Hardware. Cut it into 2" pieces. Carry one in your pack w 2 oz of sealant and rubber band one to your quart of sealant at home.

    Can't remember the size off the top of my head but take your extra Stan's tubeless stem with you to match up the size.

    I use the little nose-snot-sucker bulbs they have at the drug store. Anyone who has kids under the age of about 20 will know what I'm talking about -- they give them to you when you check out of the hospital with your little parasite for the first time. They juuuust fit into a Presta valve with the core removed, and hold about 2 oz. of sealant.

    I've been running tubeless for a few years and really folks, carrying sealant on the trail in case you need some is like strapping your pump to your pack and waiting til your tire goes flat to put more air in it, or waiting til your chain starts squeaking to add lube. It's a regular maintenance thing to check fluid levels. If you do that you won't run out on the trail. If something cuts your tire enough to run the sealant out what good will more sealant do? Carry a tube, not sealant. Installing the tube is not as messy as shortening a chain. Repeat that as a mantra while you are installing the tube. Good luck.

    You have might small tires if 4-oz of sealant fills them.

    I only use sealant if absolutely necessary, and only as much as needed (50-60cc), even in tubeless ready tires. I do not need the mess, rarely flat for any reason and change tires often.

    Sorry, took me a while to get back to this thread.

    I have a set of Mavic C29SSMax. The injector does not work on them. I also have a set of Sun Ringle Chargers on my SS. Haven't tried it on those yet. I'm guessing it might work since the stems are from Stans.

    I have a single shot 2oz bottle of Stan's that I just re-use. I use their valve core remover, fill up the bottle, insert the tip (just the tip) and done. No mess, no pulling the bead off. I don't even add Stan's when I'm seating the bead so I don't make a mess. I've got my workflow down pretty solid because I change tires all the damn time. I don't waste a drop.

    Amen to that! In my years of tubeless I've had two flats (instead of twenty). Remove stem insert tube carry on.

    My method:

    - Cut piece of camelbak hose (from an old bladder)
    - Remove valve core
    - put hose over ste, then shake and squeeze right into the tire. make sure the bead is set first though.

    I never thought tubeless was worth the effort until I started getting lots of flats one season. Buying and/or patching tubes sucks.

    I don't have removable valve cores. I am running ghetto tubeless with valves cut out of old tubes. Been running this way for almost 2 years now. Works great, but it also means I can't inject thru the valve.

    I just break about 4" of bead and use a small funnel to pour in more sealant. Very quick and easy.
    Mind your own religion.
