Cyclocross to road bike conversion

Hi all,
I am considering changing the wheels on my cyclocross bike to a specific road wheel. Has anyone has done this, and if so did you find a noticable difference in the wheel friction? Theoretically a thinner road wheel should reduce friction and therefore make road cycling easier. I am currently riding on a 35mm wide wheel, but as I have entered the open stage of the Tour de France and am therefore only riding on tarmac. Therefore is it worth changing the wheels to a specific road wheel?
Any adivce is welcome.
Cheers.
Pete

    ? Friction? You mean rolling resistance. I don't know what you mean by friction, but I thought wider tires offer better rolling resistance. But going back to your question I don't think a road wheel is necessary, but I think a slick tire would offer benefits over heavily treated tires. When you choose a tire for road cycling, generally go for tires that would match your rim width when pumped up. A specific road wheel(unless you are willing to drop $3000 on a pair of light, stiff, aero carbon wheels) will not make too much difference.

    Do you mean a 35mm tyre? 35mm rim width is wide for a cross bike. Change the tyres to a slick pattern and maybe a little thinner, but I wouldn't go less than 28mm. No need to change the whole wheel.

    Slick tyres, higher pressure, ride.

    Road wheels may offer a small weight benefit to save you a bit of climbing effort, but then just changing tyres will help with this too.

    I think most people here would agree that changing out gyres is a better value upgrade than wheels.

    Ah - now, what I would do - assuming you want to switch between tracks/trails and road - is have a second wheelset with road tyres on.
    But just for a one-off section of TdF - I wouldn't buy a specific wheelset just for that. Unless the cross tyres were really knobbly I'm not sure I'd buy a road tyre either - depends what they are I guess.

    If you are struggling to get thin enough tyres on specialized Roubaix pro tyres come with a 25mm tread and 28mm case which may help you.

    I just change the tyres on my cross bike to road tyres. New wheels just add other complications.

    It's the OP's first post. I assume he just got his terms mixed up.

    Notes for the OP:

    Tire = the rubber part in contact with the ground
    Wider tires (e.g. 32mm tires) have less rolling resistance at a given pressure than skinnier tires (e.g. 23mm tires)
    Wider tires have more aerodynamic drag a given speed than skinnier tires, as you go faster this becomes more of an issue
    A slick tire (road specific tire) will have less rolling resistance than a nobby tire (so yes you should get new tires for this, it's worth the money).

    Wheel = wheelset = Rim + hub + spokes.
    A decent wheelset is going to cost a lot of money, probably not worth it for what you're doing.

    Summary, buy new tires, keep your current wheels.
