I have an 05 Crossfire Roadster with the upgraded Startech/Brabus wheels.
I have just replaced all the tyres with Pirelli ones.
The car now feels like it is driving ice.
It is very twitchy and generally feels unsafe.
Chrysler tell that the tyre pressures should be 32psi front and 33psi rear.
This is the pressures for the standard size tyres.
We have fitted, 225/35/19 front and 255/30/20 rear.
Can anyone help?

Many thanks
