Tyre pressure

[rolyh]

Hi there is no pressure information on either door posts on my car. The tyre sizes are 245/45 z R18.
The car is 2.2D saloon. I have set the pressure to 35 psi. But as the ride is bit jittery I think that maybe the pressure needs to be lower.
Can somebody tell me what the correct pressure should be.

Hi rolyh,
Found this on the Internet:

They say 33psi front and rear.
I didn't know the exact details of your car so here's the link to check for yourself:

Hope that helps a bit.
Take care.
