Campagnolo Khamsin + Vittoria Rubino tyre = NO SKIN ON HAND!

sibelius7

Campagnolo Khamsin Wheels + Vittoria Rubino tyres.

There is no way these tyres are going on - they are so tight! 2 pairs of hands and 2 tyre levers couldn't push the last bit of rubber over the rim.
Could it be the rim tape - it's quite thick campagnolo tape (it's not plastic or cloth - something quite hard but fiberous - maybe nearly 1mm thick) or is it just the combination of rim and tyre?
I'm trying to work out whether i should just send the tyres back and get a different make. Am i going to have the same problem with every tyre on this rim?

Any advice would be great - although i'm not looking for advice like "try soap on the rim" or "remember to role the tyre over" - there are two very angry people here with no skin on their hands :evil:

I've no experience of Khamsin rims specifically but have got a couple of sets of Vittoria Rubino tyres and can recall them being a bit of a bugger to get on. I don't think rim tape should make any difference when putting a tyre on, but may do when you want to take it off.

Assuming you have inflated the inner tube slightly you could try deflating it completely once you get to the part where the tyre won't go over the rim. Then go round the wheel squeezing the tyre and removing every last bit of air. You might find that creates enough slack for the final push.

Got to be the wheel, I've got Rubino's on mine and they go on by hand, no levers required.
I've only got cheap wheels though

My wife manages to get rubinos on and off her Khamsims.

I did get her one of these:

to make it a bit easier to get on though.

rubinos are actually the easiest to get on my khamsins. MTFU!

Putting on Vittoria Rubino tyre on my new Ventos was a right nightmare, about 1 hour per wheel and thumbs throbbing at the end, really really really hard to put them on.

I've had trouble getting Conti's onto Campag rims before but found a guide on YouTube where the guy shows you to go round the rim making sure the tyre is as far as as possible.
I've used a VAR lever for the first time recently and they're really good.

I've got the same Khamsin/Rubino combo and I can confirm it's a pig of a job getting them on and off!

Ah, the joy of owning wheels with Campag rims. Fixing roadside p***tures are so much fun.

Get rid of the thick rim tape, it's not doing you any favours - a thinner tape gives you more 'wiggle' room.
Talc the inside of the tyre - it slides easier over the rim (reduces punctures too).
Technique + right tools. Positioning the tyre to give you the maximum amount of room for the bead is key + a decent tyre lever helps, sometimes needed for the last section.
I've fitted some of the most b*$tard-tight 20mm tyres to 'over-size' rims using hand pressure alone - check out the clips on YouTube

once the tyre is on, to the last bit you are stuck with....


Go round the whole tyre on the opposite side and push the rim into the middle of the wheel.

Then try and push a little more over on the other side you are struggling with.

Repeat a few times and it will work. There is a great video on here that loads found useful - can't find it though!!!

It is definitely a practise thing. I use Rubino pros and Corsa Evos on 2 lots of Campag wheels (Neutron & Khamsin), Fulcrum R5s and Mavic Carbones.

They can all be a pig getting them on. Even more difficult getting new tyres onto new wheels, but seems a bit easier getting new tyres onto used wheels.

Very strong, or long tyre levers help no end.

Not a problem with my Zonda's and Ultremo tyre combo. Dont need rim tape with Zonda's - maybe thats the reason.

+ 1 for trying a different rim tape. The first time I got a p***ture on a road bike we (had to get someone else to try too) took forever to get the tyre off, and then on again (all the time being eaten alive by midges). LBS changed the rim tape to see if that would make any difference and it did, HUGE difference for such an apparently small change.

Lean the tyre against a radiator for 30 minutes or so until it's warmed up, it makes the rubber just that little bit more elastic and that much easier to get on.

Take them to a bike shop

Be careful doing that though, if the radiator is quite warm, or you forget about it, you can melt the carcass.

Different rims and tires require different methods to get on, you just need to learn which works best with your combo. I've had some tires go on extremely easy, and others take alot of work.

If you come back to a rubber pizza it's been on too long.

I'll give this a go - i watched a video of an old man putting some schwalby marathons on using some ties and this technique. I'll give this one more try before i rip the rim tape off and stamp on it in anger.

And yes, i may well need to mtfu

was this the video? this is the method i use,seems to work

Managed to get my Ultremo's on my Khamsin's with just my hands.

It's not the wheel, it's not the tyre, it's you!!!

Ribble must have got the Rubbino's mine came with on somehow, try them!!!

VAR levers or one of these: http://www.dotbike.com/p/3845

About to purchase both after a nightmare getting my Stelvio+ on my old 105 wheels - VAR for the road, tyre mate for back at home.

Exactly that, I'll let you know if it works tomorrow.

Or one could try these

MattC59

I've had no problem getting Rubinos onto my rims. Sounds like it's the thick rim tape you mention. Get some Velox rim tape and you should be laughing.

I can now confirm that this man is a legend! Spread the word!

I had no idea that technique played such a big role. After watching that video, i grabbed some old speaker cable Velcro ties and proceeded to mount the tires first time with no additional aids. It still took 5-10mins of wiggling, but what a difference! Yesterday i would have placed money on no-one being able to fit those tyres on my rims.

Scrumple

Yes

All the posts after my tip seem to add idiotic ways to help - like warming a tyre (seriously, there is no need).

Watch the video, learn the bit about pushing the opposite side in to the middle, and you will do any tyre.

http://www.youtube.com/watch?v=-XUFVrl0UT4

The witchcraft most posts on here advocate will not make the difference.

This technique helped my old man do a tyre in 15 seconds, that he had struggled with 4 times and given up.
