So ive been trying to seat a new Nobby Nic onto my tubeless rim for the last 2 weeks without any luck at all. Ive tried the soap and water trick, ive retaped the rim with Stans tape, Ive used an airshot, numerous CO2 canisters, ive even had it tubed for a week to make the bead seat in the grooves for a while..and still the little blighter will not seat. I know that the wheel is fine as i managed to seat my mud tyre tubelessly all winter. Any ideas what else i can try?
Since I bought an Airwave pump I've never had a moments problems with setaing tyres including a new NN yesterday.
I don't like Stan's tape, the Bird stuff is much, much better; but if you have already sealed the rim (sure?) then you are just destined not to run this tyre tubeless.
A strap around the outside of the tyre pulling it in a little. This should splay the sidewalls out a little and help.
leave the tube in...
Friend had this problem recently. We gave up and went to Brixton cycles. They first tried with a pump that stores the air which didn't work. They then pumped up this Schwalbe air canister thing which worked first time. It was a 2.6 NN, so needed a lot of air. The sidewall seemed really stiff and not really sitting very well in the rim.
Have you tried a 3l pop bottle inflator?
When you removed the tube did you break the bead on one side only ??
Have you removed the core from your presta valve ??
A nobby nic should inflate easy with a single co2
I would give the rim another layer of tape- sounds like your bead may be a bit baggy!!
Is your problem not being able to inflate it, or being able to inflate it but not being able to get it to ride up onto the bead seat all the way round? My exp. of Schwalbes is that they can be a tighht fit when new.
DId it seat with the tube?
TBH it all sounds like a lot of hassle to fit the world's most consistently disappointing tyre...
Cant get it to seat, or even make a pretence of inflating. It seats fine with a tube, but it simply will not seal when tubeless. The bead does seem almost too big for the wheel - both 29er - is that possible?
I had a Small Block 8, proper UST, that just wouldn't seat. It's really not worth the anguish to keep trying - tube it or get another tyre. Occasionally you get one that just won't go. Even another Nobby Nic might work.
Currently running Schwalbe road tyres - The front was a piece of piss to fit, but the rear, fighting, dripping sweat on the garage floor, eventually got it to go, but for a Tubeless Easy... arf!
Yeah, if it's not a snug fit getting it to inflate could be a real pain. I'd definitely try another wrap of tape to help close the gap
Swear at it. Then Stab it. Then cut it off the rim. Then stamp on it. Then wee on it. Then burn it. Then smash the melted goo into the ground with a pair of bombers. Then go to the local bike shop, buy another and get them to fit it, and if they ask, deny ever trying to fit the previous one yourself to save your pride. << That's probably what I'd do.
Bounce the tyre on the floor where you can hear he air escaping as you pump it up
I pulled the bead onto a rim a few weeks ago.
You could see the pump almost catch then it deflated so starting at the valve i pulled it whilst pumping.
Sod doing that again.
As Dez B said sometimes you get a tyre that just won't seat,which sealant and rims are you using ?
Is the sealant pretty fresh?
Seat the tyre with a tube in.
Carefully remove just one bead.
Put tubeless valve in.
Place wheel horizontally on a bucket, with seated bead at the top - other bead will now tend to sag into position.
Inflate until the loose bead snaps into place.
Leave for a while, to settle down
Let air out of valve and remove core
Insert sealant through valve.
Reinflate
If that doesn't work - nuke it from orbit 😉
turn tyres inside out for 1 day . pushes the beads out .
Is the rubber bung on the valve preventing that part of the tyre bead from sitting in the rim properly (and hence creating an air hole)? I always undo the valve ring a bit, push it 'into' the rim, seat the tyre bead at that point and then retighten the valve ring.
As above. Sounds like you've done the usual stuff.
You could try sloshing sealant all around the tyre and leave it to dry, see if seals any holes?
Personally, I'd just take it to the lbs and use a compressor.
I had a schwalbe one pro road tyre I couldnt set up even with an airshot. Compressor worked straight away.
A while a go someone posted an excellent video on one of these 'tubeless help' threads where the guy seated the bead with a tyre lever. I haven't been able to find it since! 🙁
The best thing i've used recently are either
1. a 29er tube stretched around the outside of the tyre when fitted, this helps push it all onto the bead area etc.
2. Use some bungee straps to do essentially loop around the spokes and tyre to do similar to the above too.
One time i had to grab Mrs Weeksy to come into the garage and hold a little bit, but even that failed so i went with Option 1. That hasn't once failed me at all in recent months. It can be a faff getting the tube around the outside and you need 2 spare arms !
Compressor and a strap of some kind round the tire (bungees, rope, inner tube etc) have worked for normal tires andf at bike tires alike for me.
I had a 26" superstar carbon rim which was a nightmare to seat a conti x king onto, it would seal but not snap into place no matter what pressure was in it using soap etc. I used silicone lube that you use to assemble drainage pipes and at about 60 psi it popped on. Glad I never got a flat out on the trail cos getting it off was another story, it would have been ride over
Airshot. I have been so impressed with mine. I'm waiting for the combined airshot and track pump. It can't be long before someone releases such a device.
+1 for compressor. Also add a couple of wraps of tape until its sitting fairly snug on the tape. The main issue with Schwalbe tyres is always the fit. Either tooooooo tight and impossible to get on, or baggy, but baggy can be fixed with more tape...
Lever method probably only works for tyres where you don't need a special method in any case. Never got it to work, always end up not being able to pull th tyre lever round as the tyre is too tight.
Onza ibex's - couldn't get those ****ers to seat even with a 6bar compressor at work. Caught once and inflated but went straight back down again. Figured if I ever lost air on the trails I'd never get it back up again so went tubed.
As a complete opposite, just fitted a maxxis minion SS to a crossmax rim, two strokes on a track pump and it was up.
OP, does the tyre have a yellow and black tubeless logo in front of the n of nobby? I struggled for ages trying to get a NN to inflate and gave up - there was no logo on it, but when you've only seen the ordinary version, you don't know what the tubeless looks like. Now I see how tight the bead is on the actual tubeless version, I'll try again with that.
