    I have a set of Michelin Pro5's. These are, I suppose, the Gatorskin competition from Michelin while previous Pro's were racing tires.

    In any case, I got the VERY tight rear wheel tire on without exceptional problems but I haven['t been able to get the front tire on without pinching the tube. Getting the Continental tube on is completely out of the question so I've been trying to use
    the thinner Specialized tubes. I've pinch flated three of them though one of them seemed OK but the next morning it was flat. The tires are tubeless ready but there is too much wear in the Presta filler hole and it leaks air to rapidly. So I can't put
    air in fast enough to seat the tire on the shelf on either side.

    The Pro5's are so tight that you can't put them on without levers. I tried using a Kool Stop plastic tire Jack but the bead broke the end of the jack off before it could push it over the edge. I've ordered a new one but I would like to continue the build.

    Does anyone have a trick? Trying to push the bead over the rim by hand has now torn the skin off of my fingers.

    Check your rim liner(s). An overly thick liner or two in
    layers will behave like that. What rim? Few modern rims are
    overly tight. although some 'tubeless compatible' models are
    noted for having not enough drop from bead seat to rim
    center, which is the critical aspect for tire changing.

    That's a good idea but the wheels are Shamals and don't have a liner

    Unless I’m very out of the loop I thought all rims at least clinchers be
    they tube or tubeless hooked or not, needed rim tape.

    Only rims with spoke nipple holes on the inside.

    My MGB with spoked wheels had rim liners under the inner
    tubes. My Corvair doesn't.
