Help!
Getting ready for my boxing day ride, i put a new anlas capra x on the back of my ktm 1190, but the fker just doesnt want to pop up on the bead. I have tubes as the rim is leaky. Does anyone have any tips for getting tubeless tyres to seat with a tube?
Went up to 75 psi bit dont want to go any higher.
The previous tubless mitas tyres seated easily

Nothing specific, but the coarse interior of a tubeless tyre isn't designed to play nicely with tubes and may wear then faster?

Plenty of lube on tyre bead and wheel rim.
Is the tube pinched between the bead and the rim stopping it from seating
70psi pah
Put more psi in.
go on its Christmas
On another note you may get vibration at speed with a tube in a tubeless tyre as the tube may move about inside the casing.
It may also rub through the tube eventually.

I will fix the leak at some point, i just need the bike on the 26th.
Its been like this the whole time i have had the bike
Using fairy liquid for lube. Would durex tingle work better?

Not sure it'll help here, but a trick I've used for stubborn tubeless tyres seating is to put a ratchet strap around the middle circumference of the tyre and crank it down a bit, so any added air is forced to go into pushing the walls out to seat the bead.

Funnily enough, someone else suggested that, but the only ratchet strap i had handy was a crap one and the ratchet just broke. Need to get innovative. Might be able to get one from the motorway services boxing day morning if i cant fathom something tomorrow

Have the same experience sometimes with mountain bike tyres and we use shaving foam around the edge of the tyre and it helps pop it pop onto the rim fully.

It’ll sure make it tingle when it pops on.
Lots and lots of soapy water.
In car and commercial we’d use something like wd40 at a push but on a bike tyre no bloody way.
Is the rim clean and shiny
More lube and pressure the better

I've used the old Top Gear tip - Deodorant (they generally use propane as a propellant) and a lighter

Works a treat - the key things are you don't need much and to pull the tyre close to the rim so it blows on to it

Windowlene..... excellent rim lubricant and evaporates away without residue.
If you don't have a ratchet strap, try a length of rope and tie a tourniquet with a bar and wind it on until the tyre compresses around the outer circumference.
And then keep going with the pressure until it realises you mean business.

Never heard that one.

In any case the Capra X is tube and tubeless. Got them in my Tenere. Great tyres.

While I'm more familiar with car tyres, I remember it coming up in a discussion over running tubes in a nominally tubeless tyre (due to a rim that wasn't tubeless compatible), and it does seem that tubeless tyres have a less smooth surface internally.

My old Motoguzzi has tubed wheels so I use tubes (the tyres are claimed to be suitable with or without tubes BTW) but, due to the rough texture of the wheels, tyres are an absolute bh to fit - need loads of lube and plenty of heat to get them on and they are a real pig to set the bead (if that's what it's called on a tubed wheel?).

I've had to go to 100psi plus to get them to seat before, though I have found since using Bridgestone rather than Pirelli they have been a little easier as the sidewalls seem softer.

Back yonder I was one of the few who rode a bike through the winters in Denmark. Looking back, utter madness. smile

Anyhow, whenever I changed my tyres I had to remove the crud that had developed at the top of the rims, right where the tyre sat at its top - often it was so bad and tough I could only cut the tyres off. They were cemented on through the road dust, grime and dirt getting trapped there.

If I did not clean the rims with a wire brush on a drill, they would never, ever seat the new tyre.

Give it a try, might be some decent detergents/cleaners that can remove it more easily these days.

If you are using an inner tube inside a tubeless tyre it is the same issue - the rims need to be clear of crud so you can get a clean on clean seal.You won't notice it as much at first, then you start bobbing up and down as you ride away.

Ratchet straps and it popped on all the way round at 65 psi
All good thanks for the advice. The capybaras are great, good up the wet bing, and better road manners than mitas.
Although the bd thing just developed a new fault today, one i havent had, or even heard of before. I love ktms.

Understand the same, tubeless only tyres historically are rougher inside than tubeless - you're OK if it says 'Tubeless - on tube type rim fit inner-tube' or something along that line.

The valve hole in the wheel rim will be bigger for tubeless tyres, you used to be able to buy a reducer thing to bring it down to fit the tube size valve.

What compressor are you using? I suspect that's your problem.

You don't need anything massive, but a cheap 25 litre compressor connected directly to the tank with the valve core removed would do it no problem.

That is a st hot compressor for a 12v model, works great on van tyres and is properly rapid. Havent had to fire up my abac for tyres since i got it.
It wasnt the compressor, it was using a tube with ktm tubeless rims, and its a firmer tyre than the previous mitas. The ratchet strap trick worked easily.
