Tyre pressures e85

Hi, just looking for some help with tyre pressures on my 07 2lt e85 front are 225/45/18 Bridgestone run flats rear are 255/35/18 Bridgestone run flats. TIA
 
Your tyre sizes are not the OE fitment..fit front should be 225/40 18..🙈

Tyre pressures and many other wheel related data is here..

Pressures for stock tyres are 2 and 2.2 BAR👌

Hello and welcome to the forum. Sorry you were met with such a banal first suggestion.
[ref]B21[/ref] is correct, your sizes are not standard, though not an unheard of change.
With tyre pressures there are so many variables, particularly the discussion around runflat and non-runflat pressures.
May I suggest you follow the advice given by Peter and start with 2.0 bar front, 2.2 bar rear, then see how that feels to you.
You then have the option to tweak a little around those figures until you reach what feels best suited to your local roads and driving style.
