    michelin pro4 service course tire pressure

    Do these need more or less PSI than usual? I couldn't quite figure it out.
    It's smooth but it's a bit buzzy

    That will depend greatly on what your "normal" PSI is, what width you purchased and what ride quality v/s grip characteristics you prefer.

    i'm running 105-110 on GP4000s 23 for example?
    the Pro4 seem to corner well and have lower rolling resistance.

    I will assume you bought 23mm....

    Run the same pressure. Evaluate performance. Good? Bad? Adjust pressure if required and evaluate performance again.

    I'm running Pro 4's in size 25 @ 100 front and 110 psi rear, and for me it's the sweet spot.

    That's about 15-25 less psi than what I always ran on Vitt EVO and Diamante tires.

    I weigh 187.

    YMMV.

    What width rims (standard? 23mm?) do you use?

    There's so many variables in this equation:

    road surface
    rider weight
    rim profile
    wheel characteristics
