Hi all!
I have a Triban 622x17c rim, and I want to mount a 700x28c tire on it. Technically, I tried the following:
- Starting from the side opposite the valve.
- After mounting the first bead of the tire, keeping it in the center of the rim (in the groove).
- Working from the opposite side, moving toward the valve to finish there.
I tried heated the wheel, but nothing helps. The last 45° is just an incredibly tight rope that I can’t even hook with tire levers. It feels completely impossible — please help me, what am I doing wrong? On my MTB I always managed only with hands, but a road rim is just pain and tears.

(In the photos, I’m already trying to move slightly in the other direction from the valve)
Work both tire beads to the middle of the rim so that they sit inside the groove. Redo that as often as needed. Use soapy water to make the final part slip on the wheel. You can also use cable ties to prevent the tire from slipping off the rim on parts where you already managed to work it in.
It takes some practice, but you will do it.
Have you tried levers?
My friend has the same rims and they have always given us a whole world of pain when he has punctures on the road during our tours.
The thing that really revolutionised installing tyres for me was ensuring the bead on the whole of the tyre that is already semi-mounted around the circumference of the rim is pushed into the centre of the rim. This enabled me to stop using levers, which inevitably pinch punctured my tubes.

You are probably not doing anything wrong, those Decathlon Triban wheels are notoriously hard to fit tires onto.
I’m not sure why, if it’s the tubeless tape that’s too thick, or their manufacturing that has too small of a margin.
But I had horrible compability with Continental as well.
I ended up swapping to DT swiss after some time.
Nothing, it’s a Vittoria tyres, they are all the same to mount.
There’s a tool that helps leverage it over. It might scratch the rim a little or leave plastic behind. I find it great though

Otherwise tyre leavers and lots of shouting till it pops over
Didn’t read that you already got tire levers, mb
Remove that yellow “tubeless tape” in the wheelset, it’s junk. Then your tyres should go on reasonably easily. Use tubes obviously.
Non, que de mauvais conseil !
Liquide vaisselle ou savon ou lessive, tu l’appliques au doigt le long du pneu tu vas voir ça glisse tout seul
I’ve had a few rims that the gutter of the rim isn’t deep enough. I’d measure it with a piece of string, then compare it to another rim you have hanging around. With one particular rim I tried several different tyres till I found one that was fit-able. I had to find a thinner rim tape or use the velo rim plugs. Because I was the shop owner I could waste time to get a solution. I only went through this a couple of times then started telling the customer to get a new rim. Remember; if you get a puncture out on the road you need to be able to change it. So do yourself a favour!
I have the same wheels and the same trouble trying to fit a Vittoria Terreno Dry. It’s also really hard with Continental tires.
You can’t do anything it’s the wheel…
You need to practice and hope you don’t get a puncture ahah
Also with time the tire soften a little bit and it became easier.
You are doing nothing wrong, I also have those tyres and they are a nightmare to work with, same as the Michelin Power Endurance I have on my main bike. You need a combination of experience and good tools in order to fit them.
I’ve been there fitting GP 5000 onto DT Swiss rims. Had to give up using levers as I kept pinching tubes. In the end it just took a lot of effort perseverance…. and two very sore thumbs. Just keep working around from the opposite side pinching into the centre of the rim and using as much force as you can to get the tire on almost millimetre by millimetre. Then back to the opposite side pinch it back to the centre of the rim and keep going you will get there eventually.
