ARRRGGGHH BLOODY Stans BLOODY rims and CHUFFING Maxxis tyres
Stans current rim designs appear to be aimed at non-tubeless ready tyres with slacker beads than many of the TLR etc tyres that most of us seem to favour these days. I returned a Crest wheel because I couldn’t get a tube and Schwalbe tyre mounted for love nor money.Posted 3 years agospeedstarSubscriber
Ripping tyres is something that will render a tyre non-functional if it’s large enough. I always carry a tube when tubeless in case of this but I don’t think there is any higher a rate of tyre ripping with tubeless as opposed to tubed. Quite possibly the tyres involved were more vulnerable?
I have been running tubeless for 3 years. In that time I ripped one tyre to absolute shreds but that was because I hit a rock very hard whilst almost at 90 degrees to planet earth so I don’t think even if I had been riding with tubes that anything other than what happened would have occurred. Nothing in mountain biking is a panacea but it’s all too easy to label something as a problem when in reality it’s just comparable to other ways of doing things. On the plus side I have not suffered a pinch puncture yet whilst my mate has had 2 on his new bike in 3 weeks of owning it!
Everything has a down side naturally and its not sensible to state otherwise.Posted 3 years agotenfootSubscriber
I had big problems getting tyres (with tubes) on my Arch Ex wheels.
The good people here recommended purgatorys by specialized.
I got these on but they wouldn’t seat properly, so this afternoon I left both tyres out in the sun, so that they were nice and warm, and then got the washing up liquid out.
With a bit of careful manipulation I now have 2 properly seated tyres. I thought the rear wasn’t going on properly in a couple of spots so I pumped it up to 40 psi to push the beads out. I nipped indoors for something and the tyre seated itself while I was indoors.
Might be worth a punt with purgatorys, maybe, even if you just buy one for now. £30 gotta be better than new rims.Posted 3 years agodazzydwMember
Got 26 FLOW on Hope hoops, running with tubes, and have had huge problems getting any of my Conti, Schwalbe, Maxxis tyres on. Similar tales of woe with biker colleagues. Lube, fairy liquid, teeth gnashing, thumb breaking, lever breaking experience. Not in a position to throw them away and get non Stans, but won’t ever go for a Stans rim again.Posted 3 years ago
but it would seem odd that a rim would be designed not to work with tubes?
Stans work by having a shallower rim bed to hook dist/depth than std rims and that helps UST tyres seal. It also makes seating a normal tyre and a tube a PITA in many cases ime. The tube doesn’t apply even force to the tyre there in the same way as air does in a tubeless system. Maybe a very thin, well talced tube would work, but a normal one on a tyre with a load of dried sealant inside, unlikely. They’re not really designed to work with tubes unless it’s a better option than a cut tyre that won’t seal.Posted 3 years ago
I’ve got Flows and Maxxis or Conti USTs to seat with a tube in using a bit of dry lube but it’s one of those things rarely needed, just for those occasional cuts that will flat any type of tyre.
I can remove and fit tyres with my thumbs, I don’t even need a lever – that’s not the issue, it’s getting the beads to seat when inflating that I have issue with. I accept of course that’s it’s entirely my fault for doing it wrong and using tubes on a tubeless only rim (althoug you can of course run a tube purely as a get-me-home fix).
I’ve been offered a couple of different 29er tyres to try both for fitting and for whether I like the tyres, so I’ll see how they go before getting spendy on new wheels I thinkPosted 3 years agoNorthwind wrote:
Where did you get that from? There’s no such thing as a tubeless only clincher.
being a bit melodramatic, perhaps 😈
but reading through this thread, all I can see is people who haven;t rea the OP and are telling me how to seat tubeless tyres, or people saying I’m wrong for using tubes on a rim designed for tubeless

does suggest that Stans rims are primarily designed to work tubeless – not to work with tubes as a default then improved to work tubelessPosted 3 years agowarns74Member
Arch EX 29 with Ardent 2.25 (summer) and Beaver 2.25 (winter), both tyre types fitted with tubes and no issues whatsoever?
Only ever needed levers to get the tyres off, will go on fine just with fingers once the bead is in the center of the rim channel. The Ardents “pop” on nicely I think the Beavers didnt but I deflated them to check the bead was properly located all the way round and been using them for over 8 months without issue.Posted 3 years ago
both tyre types fitted with tubes ….. The Ardents “pop” on nicely
To back my point about Stans rims design and tubes, that ‘pop’ doesn’t happen when using tubes on std Mavic rims – it’s the rim hook dims that makes that happen and it’s the same thing that means other tyres with a fraction smaller bead diameter sit with a wobble. Or, tubes just don’t have the even pressure to pop it into place.
Stretch them out a bit with another rim and higher pressures, use some moto-x bead cream, it’ll help as it’s very small tolerances that make a difference.Posted 3 years ago

It can- I’ve had it with at least some of my mtb rims, couldn’t tell you which ones but probably the 717s or 721s. And my Open Sports definitely do itPosted 3 years ago
