The reason the gas mileage is better at higher tire pressure is because of less rolling resistance. The tire is harder and does not flex as much, thus it rolls easier.

Make it Easy
Just inflate your tires to 35psi (cold), and you will be fine. Ambient summer/fall temperatures where I live are above 90 degrees in August/September, and my tire pressure sensors show maximum pressures of 40psi after a few miles. That's good.
The biggest issue in the front tire feathering problem (other than mass hysteria) is that tire preasures are not kept correct. The low profile tires on the 350Z need to be checked AT LEAST once a week. If the pressure falls below 30 psi, you will have tire wear problems, even though your sensors don't give you a "low pressure" warning.
Driving a 350Z means never having to say you didn't pay attention.

I'm running 28 in the rears cold right now (dropped from 33 last night, haha) and about 30 in the fronts. I get really good traction though, . ANd my tires are already bald. Gotta get new ones after the winter so I like the traction.
