    The following from the Catera 2000 User Guide

    The Tire-Loading Information label, which is located
    on the rear edge of the driver’s door, shows the correct
    inflation pressures for your tires when they’re cold.
    “Cold” means your vehicle has been sitting for at least
    three hours or driven no more than 1 mile (1.6 km).
    If you’ll be driving at speeds higher than 100 mph
    (160 km/h) where it is legal, raise the cold inflation
    pressure of each tire to,

    - 38 psi (260 kPa) for tire size P225/55R16
    - 39 psi (270 kPa) for tire size 235/45R17

    When you end this very high-speed driving, reduce the
    cold inflation pressures to those listed on the
    Tire-Loading Information label.

    So from this I have to assume that 17" rims with 235/45R17 size tires should be good.

    Better check with Tire manufacturers allowed tires guides when you search for your car to be double sure.
