So my Conti 4000s 25mm arrived and I'm in the process of putting them on now.

However, I'd not taken into consideration the tube size. My Vittoria Ultralite tubes say 700 x 19 - 23mm.

Is this going to cause me a problem, should I have 25mm specific tubes?

    ^^ Thanks. I assumed it would be OK.

    My pump (joe blow) seems to be having a problem getting them up to pressure. After 90psi its really struggling, though thats probably the pump and not the tubes.
