35 for decent comfort and mpg... 32 for a little better traction...

I run 32 in rear and 35 in front for street driving... drop rear some and front up for drag strip.

 

Nope, you still go by the car's tire pressure specs even with aftermarket wheels and different tire sizes. For street driving, over time if you see that the center of the tread is wearing faster you can decrease pressure, or if the outside edges are wearing faster you can increase pressure.
