- Stans ZTR Crest 29er rim problems
I have a set of these, bought as a set of Hope Hoops. They are insanely tight to get tyres onto. I have tried to fit Conti Mountain Kings, Kenda Karmas, Bontrager somethings and (by way of experimentation) Schwalbe Kojaks and Conti Gatorskins.
I cannot get any of these tyres onto the rim without such heavy use of levers that the tube doesn’t stand a chance. Even without a tube any of these tyres is a serious fight. Getting them off is also a total pain. Bruised knuckles, damaged tyre levers, sweat and much cussing.
Are these rims notoriously tight? Is there a particular sort of tyre that works wonderfully? Any particular tricks?
Or have I just got an evil pair? 🙂
(I’m not a huge expert, but I can usually fit and remove tyres without injuring myself…)
Thanks all.Posted 7 years agobigdugsbawsMember
I have Arch EX which are just a beefed up version of the Crest and find all Schwalbe tyres no problem to get on without levers. However, tried a Geax Saguaro TNT recently and not a flippin chance 👿
You could try electrical tape or Stans yellow tape instead of your normal rim strip, it will free up some room in the central channel.Posted 7 years agobowglieSubscriber
I have exactly the same type of wheels and have fitted Maxxis Aspens and Beavers, and also a Spesh Purgatory with no trouble at all – although I run tubeless with Stan’s yellow tape & sealant. I just make sure the bead is in the deepest part of the central groove in the rim before pushing/levering the last bit of bead over the edge of the rim.
TBH, if you want to get the best out of the wheelset, ditch the tubes and go tubeless – in general, if the tyres are a tight squeeze over the rim, they’ll be easier to inflate tubeless.
If you really need to keep the tubes, you could always try a bit of washing up liquid to try and help get the final bit of bead over the rim.
Good luck!Posted 7 years agojota180Member
There’s loads of info on the notubes site about the 29er Crests being very tight with a lot of tyres, even to the point of throwing the (rather slack to start with) spoke tension off on some rears.
The latest Schwalbes being particularly tough, the older ones are OK, Bonty TLRs were very tight too for mePosted 7 years ago
Conti Race Kings are OK on minebolMember
I have found Spesh tyres generally, and Conti Mountain Kings a sinch to get on – no need for levers with the tyre right in the central groove – and I’m notoriously rubish at getting tyres on. I wonder whether it’s the luck of the batch. I had two sets of Roval Traversees, one of which was very tight, the other was not.Posted 7 years agoBigDummySubscriber
Thanks all, I’ll have an experiment.
Sounds like we may need to go tubless. I was hoping to delay it for the moment, but frankly if a tubeless set-up cannot be bodged out of trouble with a tube in the back of beyond then I’m not going to trust it anyway. Hey ho.

I think it may just be your technique it has been touched on here but the trick to getting tight tires on is to press the bead in the middle of the rim giving you the greatest space to slip the tire on. Or your running too thick a rim strip remember they are designed for the super thin yellow tape and a tight tubeless fit. Don’t give up on running tubeless it really is easy with the Stan’s rims onces set up.Posted 7 years agocoatesyMember
Start fitting opposite the valve, pushing the tyre into the well, and working it in in both directions, once it gets tight, go back to the beginning and start again. If you start at the valve then it’ll limit how deep it can go into the well, and therefore, how much slack you’ll have.To remove, push the tyre into the well opposite the valve, and work around as before to create slack at the valve where you can start removal.Posted 7 years ago
