what PSI do you guys inflate your tires to?
Ive got my gs430 (stock) set to 35.

thats a good question. I'm normaly very good about checking PSI on low profile tires, but havent been so far with this car. I have installed Tanabe springs and really should check that. Anyone played around with different pressures and tested to what the car likes best?

I've found on other cars that a few psi plus/minus can change the whole driving dynamics of the car.

#1 The factory tire pressure should probably be kept where the door sticker recommends.
#2 If you lower the pressure from factory specs, you'll be looking at the low tire pressure warning all the time.

I like my ride between 34-35psi, even though the recommended pressure is
33psi.

My TP sensors are not sensitive enough and it lets the pressure go all
the way down to 20psi before triggering a warning. Having an AWD
car I always make sure the tires are properly inflated and approximately the
same pressure all around.

I usually keep my GS300 tires at 35 lbs. Since the Dunlop run-flats ride like rocks anyway, increasing the pressure a little doesn't seem to affect ride quality much.
