I poke the cable tie buckle back inside the foam by rotating the cable tie after tightening and cutting. That way it won't damage the tire OR the rim tape.

Just changed my tyre setup today. Vittoria Martello rear, Mota front with a Nukeproof ARD insert on Spank rims. Easiest tubeless install I've ever seen, inflated instantly with a track pump and popped the bead on at 30 psi.

Just what I was after. Cheers Doddy!

[@tomalleeson4573]

Thanks Dotty. I'm going to give it a try...got tubes right now. Excellent video as always.

[@jjonkie]

you make it look so easy ! Great job

[@hallstewart]

Thanks. I tend to put the tyre on the wheel with a tube, indoors overnight. Deflate and release one side and remove the tube, then fit the valve and insert. This pre step helps the tyre take the rim shape and makes subsequent inflation and re-beading easier. I also find that watery soap is better than soapy water to help the re-beading. Hth

[@hallstewart]

One other remark: presta valves are not really designed for this being rather narrow and cores are easily blocked by tiny bits of dried sealant which leads to slow leaks. Any chance tubeless and wheels will go back to using Schraeder with removable cores as these are wider?

[@marekj.]

Very clean instalation. Nice Job.

[@eatchiles]

Thanks for the tips mate

[@raziz16]

Great video! That’s what I’d do before putting in the sealant. Make sure that the tyre walls seat on the rim properly by pumping to its maximum recommended pressure. Then only I’d fill in the sealant using a syringe. I learn a new thing - how to install the foam insert correctly. Thank you so much! 😊

[@m4tt12]

I usually seat the tyre first, then break the bead on one side, then you have more room to get the Airliner in

You can also spin the wheel on the bike to help the sealant spread 👍

How did it work out man?

[@Popotla]

Maravilloso

[@duroxkilo]

if possible push the wall of the tire IN the rim, same side, 180degrees from the segment you're working on. the rim has a smaller diameter in it's center, just enough to help a lot when fitting the tires. besides the soapy water, the greatest help is heat (sun, hair dryer, etc). a warm tire is easier to work with. *special valves mainly for weight reduction :}. a nice hole on the side of a regular valve would do the same job.

[@slavojalois1639]

I was wondering why a standard car tubeless valve with a groove filed in the end would not suffice if a little extra weight is not an issue!

[@jonathanhoare9006]

@Doddy you could have used the tyre levers much later and for far less effort if you had pushed the bead in to the deepest section of the rim. I know spank have a raised middle section but they still have a lower “well” which will give you more bead to play with when getting the last bit on.

[@hugor.b.6351]

maybe the insert makes no possible to do that... but yes with out an insert that is the right way to do it ;) and some times the only one jaja

Can't push the bead in the middle because the insert is dense not much play

Installed the air liner on my rims. Front tire perfect makes no noise and seems to me doing great. Rear rim was the same, but now I hear the liner moving back and forth on the rim. if I take the tire off the bike and wiggle it back and forth, like when you add sealant, I can hear it hitting the tire. It is cut just like the front and installed properly.... Just now pulled the liner out and checked to see if the zip tie broke... nope. Installed again, added sealant and the same thing... soo weird... Thoughts, needs some expert advice... of the good kind.. Cheers G

[@thelocalangler]

once the inserts are installed and you are ready to re-inflate the tire do you still use the same factory air pressure or is it different now?

I never understood why people do not seat the tire first and then inject the sealant through the valve. You can do this with the little Stans bottles too. I have been using Cush cores front and rear for years and love them. I want to try this Vitoria one now.

[@hugor.b.6351]

in my case i used that method but i think the sealant with a few days gets dry in the valve and gets difficult to inflate the tyre also the top of the valve when you close it don't fit perfect and lose air... next time i think i will put the sealant direct on the tyre.

At the expense of oversimplifying things, inserts are basically solid inner tubes, am I right?

[@BGraves]

No, you're not.

[@hallstewart]

No. The tyre still relies on the right air pressure to give a correct ride. The insert is partially rim protection, partly burp protection, and also gives a better compression ramp-up on hits especially. If you like to use lowish air pressure for high trye conformance

I don't recommend cush core, too heavy, feels flat tire and poor speed rolling. I had terrible accident using it while jumping on a downhill track. My opinion use a good tire with tubeless. Or use Mr Tuffy band with regular tubes.

[@TheButlerNZ]

OK a month on so probably won't get read... BUT... Is there any reason they don't make a tyre insert INSIDE an innertube. This would help save snake biters.... The insert wouldn't have to be full tube diameter, just big enough to squash out into the sidewall on impact, keeping the tube from being pinched between object and rim... so could actually have an air gap between the top of the insert and the outer tyre mid tread making for a softer more pliable contact area for grip when not hitting a curb/rock etc. You can fit a 2.5" tyre over an inflated innertube (Done this lots to prevent twists during inflation and in some cases is easier than a completely deflated tube installation). I'm almost tempted to get a 26" insert [yup.. I rock 26"ers... so get snake bites.. specially as the tyre co's hate us and stopped making 26" plus (ok except for Surly Knard 26 x 3.0 but I'm not disgustingly rich enough to afford them)]. get a 27.5 inner tube. cut the insert and tube. Thread the insert into the tube and roll one end back a bit. Glue the insert ends back together Roll the tube back over itself and glue that with repair patch rubber cement. (Maybe even put a couple of the really thin repair patches over the seam as a gusset.. and I'll probably go stick a nail it in instead... mmm ok so what about putting in some #Muc-Off Innertube Sealant q8)

The picture is a bit deceiving - there is WAY less space in the center of the frame than it shows. The suspension connection takes up the entire thing. So I needed to attach my battery on the bottom of the frame and my controller on the top. Instructions for assembly were lacking but honestly it wasn't too hard to figure out even though I have very little bike knowledge. Watched some youtube videos on adjusting the disk brakes but that was it. Still, I am loving it and very happy with the purchase.

[@nicolapellegrino1072]

Tried many of them... the struggle to fit on the rim doesn't repay on the trail... the main problem of inserts is the type of tire you've been using them with, to install and remove them easily you have to use trail casings such exo for example, if you use them with dh casing tires will be a nightmare to install them, second problem the sealant, with rotation and friction between tire and insert the sealant will consolidate in lumps that will make unstable the tire and you have to remove the insert to resolve the problem, third problem is the snakebite the tire if you use a pressure too low and you're going to damage the bead and there's no way to fix the problem if you don't have an inner tube because the damage won't seal the tire on the rim.. I've had all af these issues with foam inserts, so I don't recommend that solution, Cuschcore is a good solution imho, but only if you are racing because install and remove it in case of emergency is really a pain in the ass... the best solution is a gravity casing tire, inserts are rubbish.

This last couple of months i use more pressure to get up hill easily and found that going down with that pressure (35) results in a more solid ride in curves and i feel i have more grip than before (24) maybe cause the less deformation of the tyre.

This was a pretty poor demonstration of how to fit a tyre. Forcing it over the rim like that without advising people that the bead needs to be in the well on the opposite side is likely to damage the bead. Tyres beads are not meant to stretch. The rim is designed with a well to allow the tyre to be manipulated over the wider section. I understand the insert is preventing some of this but you need to force the tyre under it. As for not riding the bike after adding sealant but giving it a shake. Really? Go ride the damn thing and spread the sealant properly. I usually love your videos too 😔 I did learn why the valves are different though so I’ll take that. Thanks.

Finishing my fourth season on Airliners on multiple bikes. Never used some “special” stem. Never. Just the stock ones that came with the wheels. Same for several friends who followed my lead. What on earth are you talking about? Honestly man, explain.

[@hallstewart]

“Standard” tubeless valves have a block of rubber on the end with just one hole in it. When you fit the insert, it covers the hole. That stops air escaping through the valve when you want to deflate the setup. These valves have a crown on the end that is not blocked by the insert and allows air and sealant to move freely through the valve.

[@Chuckolicious]

@@hallstewart Woah, 2 years later. Well, still using Airliners and still using stock valves with the block of rubber, and still no problems at all. And still the same for my buddies.
