I have some new unused Vittoria Rubino intrepid Profolding tyres knocking about for a couple of years so I thought I'd chuck them onto some Khamsins I've aquired Nooooooooooooo waaaaay :twisted:

They are impossibly tight. I am a 17 stone giant and I cannot get them onto the rims even with steel tyre levers and great force !
I managed to get one tyre on without a tube and left it to stretch for a week

I just tried to fit a tube and knicked it in three places.

Tried to fit the tyre onto an old MA2 rim( blimey they should take anything) but not the Vittoria's apparently.
These tyres wer'nt cheap. They are still costing £15 each so what is going on here.?

The tyres are so tight that they are wedged into the centre of the rims and even there there is no give.

Can't be doing with these . What are the Michelin Pro race like to fit ?
I used to love the Mich Hi-Lite Comp tyres they were excellent

    Get yourself a Crank Bros speed lever and laugh in the face of tight tyre and rim combinations!

    just looked and the levers are plastic ?! :shock:
    There is no way on earth they would fit the tyres I have on these rims . I'll bet the cost of a new set of tyres.
    I am using steel levers and I still can't lever them on . I can lift 200lbs with one arm but I can't fit a bloomin tyre :twisted:

    You'd be suprised how good speed levers are, even better than my steel levers.

    I use 3 levers for Vento's.

    Can you see where you have the bit not coming on? Well go to halfway, and unhook the otherside from the rim, and set it over the rim and hold it in place by attaching the lever to a spoke, so you're essentially pulling the whole thing up. It'll then be easier to pull that current overhang into place, then pull your lever off the spoke and the first side should drop back into place easy. :D

    SOME tyre/rim combos are beyond speed levers IME - having snapped at least two! I guess that some tyres are quite simply undersized - maybe even some of the same brand/model are not actually identical.

    I'd rather have tyres more prone to a deflationary-situation but that are easy to get on/off in the cold and wet (guaranteed!) than highly resistant ones that when they do go pop are an impossible struggle!

    Fitted them to new Dura Ace rims yesterday. Easy job, thumbs were more than enough.

    I just fitted some Pro Race 3s to my Campag Neutrons yesterday. I've got Var levers, and they went on ok with those. They would have been a battle with normal levers.

    Worse impossibly tight tyres I've had for fitting were a pair of Spec Nimbus Mtb Slicks which I got at the time of F&M outbreak to use on the mtb before I got a road bike.

    They were killers to fit, a puncture on the road would have been a nightmare. I replaced them, and ended up using 'em on the cycle trainer.

    Thats what I wanted to hear brilliant I'll order some up thanks.

    Meagan : I think you are dead right there. These were reduced at the time. I should have known there was a catch.

    AZZERB Good idea but unfortunately there simply isn't even the room or give to put a tyre lever in anywhere no matter how much force.If you look at pics you will see how low the tyre is on the opposite side. It is practically half height in the rim
    I have tried to remove the tyre that I did get fitted to put a tube in and I cannot even get a single tyre lever in under the tyre anywhere around the rim.




    The whole tyre is sunk below the rim edge and is in the middle of the rim.I'm going to have to use a sharp knife to cut them off the rims[img][/img]vittoria11280x960.jpg

    These tyres have not been manufactured correctly to the right tolerances and have clearly not been batch checked.
    I wonder how many other purchasers have also been ripped off £40.00 like me . They should have been re-called.
    They are not just tight or even very tight they are quite simply the incorrect size for a 700 rim. I used three metal tyre levers to force one tyre on a MA3 rim now its not possible to insert a single tyre lever anywhere remove it .I will have to cut it off with a knife

    I cannot return them I cannot sell them to another unsuspecting cyclist so I have to throw away £40.00 of hard earned cash because some unscrupulous retailer knowingly sold them cheap because they couldn't be fitted.

    There is a review of the tyres somewhere stating that one LBS refused to fit them for customers !

    Vittoria should be named and shamed imo

    You've had one bad experience with Vittoria tyres, but in my experience Vittoria tyres are the only brand of tyres that go onto Campag/Fulcrum rims easily.

    It's a bit of a fight to get my Michelins on my Neutrons, but the Vittorias went on my Ventos like a piece of cake.

    I have no problem with GP4000 on Zondas and Fulcrum 1s. Can fit by hand.

    Wierd, I destroyed a speed lever getting GP4000s on my Ventos, and most people experience the same thing with the Conti/Campag combo.

    agreed - I pretty much only use vittoria simply because I've never had a bad time getting them onto rims. I have tried the rigid ones, the folding and the 'slick' models on OE alex rims, bontrager SSR's, r561's and most recently campag eurus - all have fitted with thumbs only. I'm worried to try a different tyre as you hear so many bad things - especially with campag rims!

    I've had great problems fitting vittoria rubinos to my 105 rims. they will fit but require steel levers, broke too many plastic ones trying to fit them.

    I eventually gave up and bought some conti attack/force as one of their selling points was ease of fitting. They fit really easy but are quite costly at £40 per pair compared with £12 for the rubinos and less hard wearing as a winter tyre.

    Anyone know of an easy fit cheapo winter tyre?

    IME all tyres are tight on Campag/Fulcrum rims; some are worse than others, and Vittorias are about the worst offenders in most cases. Just about every tyre fits easily on Mavic rims and Shimano are maybe a little tighter, but everything still fits them with no problems.

    Campag really need to fix this... I've sworn at plenty of their wheels at work, and would never buy a pair; I've yet to find anything that fits without great difficulty. DT rims aren't much better in this regard, but I've only seen a few of these.

    Just fitted a new pair of GP4000S on Fulcrum 1s - went on fine by hand only - maybe it's technique?
