Toyo T1-R tyre pressures

I have recently fitted four brand spanking new Toyo T1-R's to my new ultraleggeras. Have to get fully bed them in (around 400miles so far). Currently running standard tyre pressures.

Just wondering if anyone has any experience with tyre pressures whilst running these tyres on the Clio? I know from past experience how floaty they can be(and are at the moment, due to the soft sidewalls)

Any help would be much appreciated.
