Hi all,
this has been a nightmare for ages when fitting tyres....
Does the thin line around the edges sit in the rim or out?
see pic:
Out. Checking that it is the same distance from the rim all the way round is a good way of ensuring the tyre is properly mounted.
Out - that line showing is the indication the bead has seated correctly. If it's still 'in' the rim, that section needs to pop.
cool, cheers. What's the best way to get it out all the way?
I've tried pumping it to the point of almost exploding, but it won't pop
Had wobbly tyres for years, finally going to sort it, and attempt tubeless.....
Looks like the bit at the left of your pic is yet to pop into place. Might just be the angle.
The gap between the rim and the line should be the same all the way round.
Yep, that line is in/out all the way round.
Tyres never used to be this much faff back in the 90's. 😀
First put it in, then put it out, then you administer the hokey cokey, then you shake it all about.
I spray some duluted washing up liquid round the rim and then inflate.
I'm sure someone will be selling "tyre mounting fluid" or something. After all, they can get folk to buy fancy tyre levers.
If it's not seating, don't just keep putting air in, unless you fancy cleaning sealant off your walls/ceiling/face/everywhere...
Soapy water will help lube the bead onto the rim.
oh, BTW, I'm doing this with a tube at the min. New tyre so getting it to take shape before tubeless
I've noticed on tight fitting tube/rim combinations, which is what you have here - that it's even worse with a tube in vs doing the same tubeless. I've seen a few stupidly tight combinations whose beads will never pop on the rim with a tube in no matter what you do...
But first - take tyre off, try to stretch a bit with foot on one end of tyre and pull up, douse bead and rim liberally with foamy watered down washing up liquid, and try again.
I'm now trying to get the tyre off as I'd not taped the rim. I've got one half off. I think I need a tow truck to get it off!!
I wouldn't bother fitting with a tube, just go straight to a dry fit, and once the beads have popped on I inject sealant through the valve.
As above. If you have time - with the VERY tightest combos in addition to a rim pact/cushcore I’ve left the tyre in the airing cupboard in a plastic bag with a hot water bottle. Left overnight, a doddle in the morning!

Heating the tyre before attempting tubeless fitting (in the sun or bucket of hot water) is now my 1st task, makes the whole process a lot easier - especially in the depths of winter (not much use when your out on the trails though). I usually let a little pressure out, so the tyre is flexible and then manipulate the tyre to make it move on the bead, then pump it back up (soap water wouldn't hurt either) & the pop into place
This has worked for me when the bead refuses to pop into place using a pump.
Pump the tyre up to a decent psi and put the wheel on the ground with the unseated bit of bead at the bottom facing towards you. Holding the top of the wheel with both hands pinch the tyre firmly with the tip of your trainer so as to grip the sidewall and press the tyre firmly against the ground. Gently roll wheel away from you with your hands, pressing firmly with your toe. NB You need quite a firm grip with your toe to trap the tyre against the ground and pull the bead into place. Grip provided by trainers works well - does not work well with flip flops!
It's a sign from your tyre - it's screaming at you to replace that orange rim with a black one.
NO WAY! Orange rims rule!
I managed to get the tyre off with a screwdriver! Taped it up and then used my 25 year old Co2 canisters to inflate. Worked 1st time!! A miracle!
The tyre hadn't quite seated so I attached the track pump and gave it some more. It must have got up to about 200 PSI before that last part popped.
Thanks all!
Just got to wait to for the front tyre to arrive now....
I ordered this back one from ChainReaction at 20.30 last night, it was on my doorstep by 0930. this morning! amazing service!
As above soapy water around the tyre beads helps with popping. Before I discovered this one method was to drop the tyre pressure fairly low and go up and down the street a couple of times and then fully inflate. It worked albeit not every time.

If you genuinely managed to get anywhere near that in a MTB tyre I'd expect fairly spectacular results, and not in a good way.
I find bouncing the wheel with 40-50psi in it is generally enough to get it to pop on to the rim properly. If not, diluted washing up liquid.
As above, I'd go to 40-50 PSI (whilst hiding behind a door) trying to get a stubborn tyre to pop.
When I normally have trouble it's on the rare occasion a puncture won't seal and I've resorted to a tube. Trying to get a tyre reseated using a mini pump, and with an inner tube attaching itself to the tacky half dried sealant on the tyre can be a nightmare. Time before last I was on a multi-day ride and in desperation used a mini shower gel from my luggage, and the CO2 cartridge I save for the 'everything else has failed' last ditch option to get the tyre reseated. After about an hour I got it good enough that it didn't feel like I had to ride on an egg shaped tyre for another 50 miles.
The second time, a huge nail through the tread and out the sidewall. Same old trouble trying to seat the tyre, in the end I gave up with the tube and managed to plug and patch the tyre, and use the desperation CO2 canister to get it reseated. That was on about mile 10 of a 100 miler!
