    Yep should be fine,dependent on if your carrying weight,or doing a long drive.
    I usually run at 35 front and if loaded for travel 36 rear on 225/45/r17.

    Rule of thumb is twice the rim size plus 1 or 2 psi. That sive should be in the handbook but tbh I would put at least 36-38 and i would keep an eye out for the tyre wear
    Now I need a turbo to keep up!

    I run 36-38 on my 2.2 mate on 17's. Think the pressures are the same for 17's and 18's. The big jump comes at 19's. I tend to run softer on the rear to keep it a bit more docile.
