How much air do you put in your tires? If I remembered correctly, the door jam recommended 32psi (correct me if I'm wrong). But the wheels look kind of low on air at 32psi. So I raised it to 35psi.

40psi.
Reason: reduce inner tire wear (front tires)

These are the OEM 17" 235/45-17 tires that we're talking about right?

Seems like many of you are running psi that is much higher than what Lexus recommends. I wonder why Lexus recommended such low pressure? I understand they want to keep the ride as comfy as possible, but I'm sure the owners who opted for these optional 17" wheels know that they will lose some of the comfy ride.

Yup. 40 psi is for bigger rims. I ran my OEM 17's at 33 psi.

i run 39-40 because of camber wear at 33 (factory specs). my thinking is with higher pressure, the tire contacting the road will be more on the center.

No, I meant my 17's. I recently put them back on. This was yesterday at 40psi.
