Dura Ace 7850 Wheels - how tight are the tyres?

A friend of mine has Ultegra Tubeless wheels. The tyres are so tight on the rims that she is totally unable to get them off - which clearly poses difficulties if (when) she punctures. She is looking at the 7850 CL24 wheels as an upgrade / replacement. Question being is this solving the fundamental problem of the tyres being too difficult to get off the rim?

    Not necessarily a problem with the wheel, just as likely that the tyres she's using are on the small side.
    FWIW, I don't think the 7850s are noted for being difficult, nor for that matter the Ultegra.

    Are the tyres Scottish or from Yorkshire :D

    Sorry.........I don't have a problem with the wheels just the type of tyre. Pro race 3 are easish to put on, Krylion carbons are a nightmare.

    Unlikely as all shimano wheels are probably built to the same size rather than being over and undersized. Try different tyres as above.

    I have Conti 4 seasons on mine and they are extremely easy to get on and off, I dont even need tyre levers to remove them.
    I have used Ultremo R1 in the summer and these are the same, very easy to get on & off.

    The thing that makes me laugh is Shimano state you should not use tyre levers with the Ultegra wheels - HAHA who do you think I am the Hulk?

    Mine are easy with Vittoria Open Pave tyres. Just fingers and thumbs needed. Easiest combo I've experienced.

    Just bought a set of the 50mm 7850 carbon clinchers. Can't believe how easily both Vittoria Open-Paves and Veloflex Pave open tubulars went on. The latter in particular were a complete doddle which had me wondering if there comes a point where a too-easy fitting clincher becomes an issue?

    Did you weigh the wheels before you put the tyres on. I hear the 50mm wheels are around 750-800 for the front and 875-950 for the rear.
    When a cyclist has a disagreement with a car; it's not who's right, it's who's left.

    Open Corsa Evo CX's go on pretty easily too on mine.

    Nice to see someone actually asking the most sensible question when choosing new wheels, 'will my tyres fit'.
