    Quick question for the group on 2015 Cali T. Here in the States, on the 20"rims, the manual indicates that tire pressure should 35psi in the front and 32psi in the rear (these are the 245 and 285/35 ZR 20s), the side of the door panel indicates that these tires should be only 32psi in the front and 29psi in the rear and my dealer told me that all the tires should be between 35-40 psi. What do you guys recommend? Thoughts?

    Start with 35/32. The manual is usually more up to date than the sticker on the door, and it's possible that they put the wrong sticker on the car (for the standard rims/tires, maybe?). If ultra-low profile tires on large rims have too little air, they can too easily fall prey to potholes. From there, adjust to suit desired handling.

    Handling better with firmer or softer tires?

    In-between. The factory has it about right. Run less air at the track to keep them from getting way overinflated but put them back to stock afterwards. Take out a bit from the front compared to rear or put more in rear compared to front and you can feel differences in understeer and oversteer.
