E 220 coupe 20" wheel Tyre pressures

[Dabthesaab]

Hi all my car above with air suspension has a recommended pressure of 2.5 bar any one else tried a little higher pressure as potholes are not doing my rims much good [P zero run flats] my tyres are 245/35 20 front and 275/30 rears.Any tips will gratefully be taken on board.

Is there a range of pressures inside the gas flap ?
There will be a max pressure marked on the sidewall.
