18's on a 370z

I'm not to disagree with anyone, but the front oem tire size is taller than the rear. Nissan did this so the car can understeer, which is a lot safer than oversteering. The 350z had slightly shorter tires in the front than the rear and they constantly spin out.

The traction control system in our cars is not very sophisticated, so going with different tire size should not be a problem. In the summer I'm going to run 275/35R18 in the front with 295/35R18 in the rear.

Not sure if the understeer is from how tall the tire is, rather than its width. The narrower front tire will definitely contribute more to the understeer. You're right about the TCS. It's useless.
