17" to 18" on a CLK430

[sparkymark]

My CLK430 has 17" wheels on as per information leaflet that came with the car.

Front - 225/45R17 91W 7.5JX17H2/ET37/ET35*
Back - 245/40R17 91W 8.5JX17H2/ET30*

What I would like to know please is, can I put the 18" wheels on and if so what rim size, tyre size and offset would I need
