The Quickest and Easiest Way to Add Tire Sealant

This is a quick, basic video showing the quickest and easiest way to add tire sealant to tubeless tires. This applies to all types of tubeless bicycle tires.

Thanks for the video. Worth mentioning is that it's worth to keep the little bottle. It's more eco-friendly and cheaper to buy a large bottle of sealant and use the little one to refill.

My workflow when using the small bottles like that is that I rotate the wheel so the valve core is somewhat upside down. I then press the bottle firmly against the valve stem then rotate the wheel to the bottom so the sealant will now pour into the tire. Once the bottle is empty I will of course reinstall the valve core. When I inflate, I turn the wheel enough so that when I use my floor pump it doesn't splatter the sealant up into the valve core. Not sure if that last part is useful but it seems it prevents the sealant from splashing up onto the core and becoming trapped once I close the presta valve. Of course this only works if you can get the wheel off the ground, or if the bike has been flipped upside down. If the bike is firmly on the floor I would suggest rotating the wheel just a few degrees so the sealant isn't splashing onto the bottom of the now flat tire sitting on the floor.

Great suggestions below, but missed by all is after removal of the valve core use a hex key that fits down into the valve and clear any old sealant away. I've often had it almost completely plugged and the new sealant wont flow into the tire.

Love finding a 3yr old video telling me exactly what I needed to confirm quickly! Thank you!

I’ve been using this technique for over 12 years now. I started this technique out of necessity back when I got a flat on a tubular road tire after just one ride. No way was I willing to throw it away and spend another $70 on a replacement. I pulled out the core, added two ounces of sealant, put the core back in, and went for a ride. That lasted the entire life of the tubular. Great tips!

I like this video nice, simple & straight to the point 👍

Ok. I did my first sealant re-fill on a tubeless tyre today (tyre has a small puncture that wasn't sealing). I'm not the mechanical type. Despite it looking easy in videos I thought I was looking in the face of disaster with seemingly most of the new sealant on the floor and not being able to re-inflate the tyre. The problem, which I discovered after re-inserting the valve-head a number of times, was that little threaded washer at the base of the valve stem. It wasn't tight enough and air was escaping via the base of the valve stem. Just checked the tyre and after a few hours it's holding up so...hopefully the puncture is fixed. I now feel more confident about topping up my bike sealant and am rather proud of myself!

This was a big help. I’ve been riding my road bike for years, but because of moving to a mountain community, I now have a road bike with tubeless tires. I’m motivated to learn how to care for the bike myself as much as possible. Your video was a big first step for me. Thank you!

[douglejeune]

super helpful, just went tubeless about a month ago, and was overthinking this a little (lot) thanks for shutting that down 🤘🏼

[davidstepro]

after years of trial and error I've been using your method for quite a while now. By far the easiest way to add sealant without breaking tire bead.

Good tip. If you're trying this for the first time, though, be aware that not all valves have removable cores. The valves that came with my Ultegra wheels were not removable.

[DEFACTO]

If I may suggest spinning the wheel an repositioning the wheel to distribute the sealant...

[jonjensen]

Great video. Thank you for the basic video. As you recognized at the start of the video, some of us are new to doing our own bike maintenance.

[Ghostdog]

Cut the tip of the bottle at an angle and it will fit further down the valve stem and you'll spill less sealant. Great video @Clint Gibbs straight forward! Well done

[jacko]

Thanks for the video, really helpful, I just followed the video to add sealant to the tubeless tyres on my new bike and it went perfectly 👍

[Max-jsmx]

Thank you so much, helped a ton after looking everywhere for a video to show me just this, simple and fast.

[berniecalcote]

Brand new to this. Thanks so much for helping me easily fix my tubeless tire!! Ready to ride again!

[stevenmedvecki]

Thanks for the video. Just thinking for newbies like me, might be a good idea to mention that you probably ought to spin the tire for a while or go for a ride to distribute the sealant

After the Stans Injector Kit blew up all over the place, it was promptly thrown away. (The tube that is inserted into the injector is just pressed fit not threaded. Yikes!) I tried your method. WOW success at last! A simple and effective idea. Thank You

[MichaelJ_]

Excellent, thank you! I‘m just trying this as I am setting up tubeless for the first time.
