I just got my OZ Ultraleggera 8x18 with 215/35 tyres put on, but i'm not sure what the tyre pressure should be, can anyone help me out, thanks.

34-36 psi I would suggest.

Thank you for the quick reply, I just searched google and there is alot of different oppinions .. some say around 42-45 psi and some say the same as you ..

42 psi seems a tad high, standard 16'' wheels are around 32, I run my 17's on 34 psi and a friend has 18's on a 40 profile at 36 psi.

Set it at 36 psi, if it feels to soft put them up to 38psi and so on

dont do psi but run mine at 2.1bar front 2.0bar rear seems to be alright for my 215/35's

I ran the Ibiza on the same tyres at 34psi front and 32 rear. To be honest you don't need to up the pressure just because the profile has gone down.
