    Correct Tire pressure

    I know MB recommends tire pressure of 44 & 46 psi but this seems very high compared to most cars.

    When the tires get hot this pressure would rise significantly.

    For track use, high pressure may be right but for street use this seems awfully high to me.

    What are you guys running for pressure to compromise between tire wear and handling on the street?

    Actually it is the other way roynd.
    For track use you want to drop your pressure to round 30psi.
    For road use.44 is fine

    30 psi on the track will heat those tires too much and trash them quickly.

    fill them with 30 psi cold and they will heat up to the perfect pressure when driving.
    It does.depend on what tires you.use, but for.rule of thumb this.works well enough.

    It's the load recommendations for this car/tires, MB wants at least 42 psi.

    Do 3 hard laps, get the brakes up to temperature and some heat in the tires, and that will pretty much be the pressure you end up with when starting with.30 psi

    Depends on how much high speed driving you do to. If you drive over 100 much you will definitely want to keep more than 30 psi cold in them. 40 cold is probably about right, otherwise you will trash the tires. On the track though lower the psi a bit for better traction like others said.

    Moved to wheels and tires.

    Not sure what PSI you want for the road course but I highly recommend a dedicated set of wheels/tires.
