Replacement Tires For G35 Sedan

Has anyone replaced their original equipment tires on the 2005 sedan with the 18" wheels? I have the Bridgestone Turenzas and am looking to see what other tires are recommended.
Appreciate any help!

I highly recommend the Bridgestone RE050A Pole Position 245 45 18 " tires.
