Morning folks,
I bought some Hunt 700c rims a while back which came with some 40mm Schwalbe G Ones already installed. I swapped them out for some mud tyres over the winter and tried to swap them back the other night...
I was surprised just how easily the old G Ones mounted the rim and unsurpisingly I now can't get them to inflate.
I'd say I'm a bit of a tubeless veteran, I've never failed before! I've tried all the tricks in the book but no amount of compressed air will do it. Not even close. The air escapes from all around the rim, not just the odd spot.
Has the tyre grown whilst it's not been in use?! What's going on?
My next plan of attack includes launching them down the garden.
ratchet strap around the outside to force the beads out to the rim edge?
Ive a set of Spec Fast Tracks on Mavic rims that are hit and miss inflating. Ive found pulling the tyre out toward the rim around the valve, but pushing the rest of the tyre into the "groove" inflates best. Plus a bit of soapy water.
I once spent 4 hours trying to fit one tyre with a track pump. Compressor purchase was the best move
I had this with the G-one on my rear tyre on my CX bike.
Eventually I solved it using the tyre lever trick - put a tyre lever under the bead as though you were going to remove the tyre, but instead of going all the way and popping the bead off the rim, lever it up until the lever is at 90 degrees to the rim.
Then if you slide the lever around the rim it will pull the bead onto the shoulder of the rim profile. Once it's nice and tight, repeat on the other side, after which it should inflate just fine.
There's a youtube video somewhere.
FWIW, about 6 months of riding later on the tyre gave up and became too flexible - it would burb all of its air out within a few miles but it was fine up until then. I've now got a Bontrager CX1 in its place, which seems a lot tighter (and so far seems really good).
I was so confident in my abilities that I added the sealant first.... That turned out to be a mistake!
I'll try the ratchet strap idea and then try some additional swearing and cursing.
That tyre lever trick sounds good!
Yes I do find they go slack. Also worth cooling down before you try to install (fridge, freezer etc..) and maybe wrap another layer pr two or tubeless tape.
I had to resort to a ratchet strap on my surly marge lite and Edna combo the other day as I was struggling
I've just binned by coke bottle inflator and bought a proper one after having similar issues (Specialized 2bliss gravel tyres and WTB TCS rims). Are road tyres just more of a ball ache to seat than MTB ones?
Similar exeperience here after my humble brag about converting the wheel barrow tubeless I am back to a a tube in my 40 nano.
popped a small section of bead to top up the Stans and the whole lot fell off both sides can’t get it to seat even using tube to seat one bead!
Unlike mtb which popped straight back into place with ghetto weed sprayer inflator. Rapid deflation after the valve unscrewed when adding a bit more air mid trail (lezynne nozzle - see other threads).
I wondered if old sealant affected ability to seat properly?
Is ratchet strap same as old tube? I am off to search for tyre level trick.
My current tyres are pretty slack. The only way I've managed to get them to seat is to seat with a tube, release a bead and remove the tube, use the tyre lever approach on the lose bead and then inflate with a tubeless canister.
I think that tyres do stretch; I had a set of ridiculously tight WTB tyres that became easier to fit and seat once they'd been used for a while.
Had another go. The tyre lever trick couldnt quite do it but it's definitely a trick worth trying.
I also noticed just how slack the tyre now is. I can mount both beads on and off at the same time with minimal effort. I don't think these will be going up tubeless which is a shame. They've both still got loads of life left.
I had this exact issue on a grail rim - G one going on easy with just my fingers then being brutal to seat. No special tricks I am afraid - I got it done with some perseverance, manipulating the bead as best I could to semi-inflate it to see where the problem spots were. Then I could inflate whilst sort of running my hand down that area to press the tyre out and hook it up.
I'm a dab hand at the tubeless (which isn't saying a great deal as they all generally go straight up IME), but that one was aggravating.
Even with a tubeless inflator @140ps I had to resort to the zip tie trick to get mine to inflate (even with one bead in place the other was very loose on the rim)! Damn things are still leaking from the valve and spoke holes though so all needs to come off again to find the tape leak!
My topeak tubeless inflator couldn't get a tyre/rim combo that worked 6 months previously to work. Took me ages to faff about with it. Tyre had definitely stretched
I have had the same with Scwhalbe One tyres, really tight and seat easily when new, but then seem to stretch which makes reseating difficult. I have found a couple of layers of insulation tape around the rim bed is enough to make it all a bit tighter and get the tyre to seat - generally still needs use of an Airshot. Compared to mtb tyres I have found them more problematic to fit, but managed to get them all inflated in the end. I have just added some Milkit valves to the wheels, which made fitting a bit easier and means I don’t need to let all the air out to add sealant.
