I might point out though that my manual gives tire pressure recommendations on page 161. Not sure why addie18's doesn't. For the record, those numbers are:

Sport Performance (Y speed rating) tires and All-Season
Performance (W speed rating) tires
Front 225/40 ZR18 . . . . . . . . . . . . . . . 32 psi
Rear 255/35 ZR19. . . . . . . . . . . . . . . . 33 psi


Sport Performance (Y speed rating) tires and All-Season
Performance (W speed rating) tires above 100 mph (161
km/h)
Front 225/40 ZR18 . . . . . . . . . . . . . . . 36 psi
Rear 255/35 ZR19. . . . . . . . . . . . . . . . 36 psi


Winter tires
Front 225/40 VR18 M+S . . . . . . . . . . . 33 psi
Rear 225/40 VR18 M+S. . . . . . . . . . . . 36 psi

According to my CD Shop Manual, Section 22, TIRES AND WHEEL Service Information, page 22-57, "TIRE PRESSURE FOR HIGH SPEED>>>> Where speed limits allow the vehicle to be driven at high speeds, correct tire inflation pressure is very important. For speeds up to and including 120 km/h (75 MPH), tires must be inflated to pressures shown on the placard. For continuous speeds in excess of 120 km/h (75MPH) tires must be inflated to the maximum pressure specified on the tire sidewall."
My Contis say 51 psi. Some areas in Texas (I don't know about other states) the speed limit is 80 MPH.
