Can not seat my new 29er tyre no matter what- help

[Hugo Stiglitz]

I've tried all the usual, fingers rubbed around each side to cause slack at the top last bit to fold it over. I find this works on Maxxis just fine.

I've tried washing up liquid on the rim and tyre bead. Even a bit of olive oil.


Everything.

The tyre is a Hans Dampf.

Any tips?

What are you using to inflate it?

[Hugo Stiglitz]

Ah correction, this is actually getting the new tyre onto the rim for the first time. Trying to get all the beading, the last 4-5inches over the outer rim.

You’ve told us half… what’s the rim?


(You’ve already chosen a tyre thats a bd to seat, I'm waiting for you to say a WTB rim!)

Stick a tube in & inflate it. Leave it a few hours to stretch the tyre, then remove the tube & do battle with one instead of two sides. I use a B&Q weed sprayer modded with a brake clamp to seat tyres. Works for me but I run Maxxis, Schwalbe are tough by comparison ime.

I've found a technique that works with GP5000 tubeless road tyres that works pretty quickly and they are known to be an utter git.

It does need a spare pair of hands (or using your foot) to hold the extra lever in place.

Basically work your way around as normal until it's too tight and keeps pinging off. Then use 1 lever to hold the tyre on the rim (i stand on this lever) then use 2 levers to gradually work the other side.

Oh bother.


You need a set of tyre pliers, some soap, and some swearies.


ETA: You’ll also have realised you won’t need to carry a backup inner tube from now on

A few hints here.

Easier to watch than explain.

It's all about getting every bit of the bead into the inner channel of the rim as possible. Sometimes you think you've done it but if that last bit of bead aint popping over the rim you've still got a bit of bead elsewhere not sat in the channel.

Just got to keep working both sides of the rest of the tyre into the rim until it gives enough slack to get that last bit over the top...

Last time I had this issue, a few cable ties keeping the bit already on the rim on really helped.

It never used to be like this.....

I tried that... they snapped


In the end brute palm and rolling over won... along with a Russian roulette lever nip on the rim...

Tomorrow. My hands will suffer.

Some combinations just don't work. my MTB which has disc specific rims with a very shallow well is a nightmare. Any tyre is tight. I threw away a pair of Nokian Tyres as there was absolutely no way I would ever have been able to change a tube at the roadside.

I love my touring rims. Ryde Sputnik. Heavy as a lead anchor at 690g each. But bombproof and with a nice deep well so most tyres go on just with fingers.

Yup.

OP has ended up with a particularly bad combo when it comes to seating the tyre.

This helps avoid taking chunks out of the rim during the process:

Wait until you try Schwalbe supergravity casing tyres with inserts...

A cushcore bead dropper was the answer, basically a super tough tyre lever. I snapped a few std plastic levels before using the cushcore tool.

Had this issue with some Schwalbe tyres on a 26 mtb wheel. Cant imagine how you change a tube out on a ride with your plastic tyre levers. Maybe all the pounding out on a ride stretches them a bit over time?
New bike has WTB's.....

[lickatysplit]

this is why you get 3 levers in a set 😉

This man is spot on, once I figured this out I have never had a problem fitting a tyre of any make on any rim.

I used to struggle like hell, unable to get that last bit seated, especially with modern tubeless tyres, pre tubeless you could do it with your fingers!

No lube needed, 3 plastic levers, although could be done with one.

Breaking the bead to remove it once it's on however can be an absolute nightmare!

You want actual soap, not washing up liquid.

Are all Scwalbe tyres hard to get on and off?

I battled to get a Magic Mary on and off the other night to fix a puncture on my lads bike. I thought it was just me (and that it was cold, dark and I was doing it outside with a head torch on).
