Just purchased some PIAA Rozza'a and need some help with getting a good setup with the tires. I have done searches on this but came up with a lot of conflicting info.
Anyway, they are 19x9 and 19x10 with +25 offsets. I found some people go with 245/35/19F & 275/35/19R
Also see 255/35/19 and 285/35/19

Definitely don't want to interfere with my VDC/traction. I read about the 3% rule. So, any recomendations and even explanations on which is better would be great.

Go to the Tire Rack. Select 350Z and 19 inch wheels. Pick wheels the same size as yours. The proper size tires will be annotated.

 

Tire rack will recommend real small tires. Sure they fit and work, but might as well go bigger.

 

As far as VDC, you should be okay with either of your two choices. One thing to worry about would be rubbing with 285s, but that's all dependent on your offsets. Also, some tires are wider than others even if they are the same size.

Another combo to consider is 255s/275s, which would result in less understeer. Do your own calculations to see if it will work with VDC though.

I have the '06 rays with 18x9s in front and 19x10s in the rear. I need tires as well and am considering 255/40/18s and either 275/35/19 or 285/35/19. I'm unsure if I should get the 285s. Unless you have big power, I think the only advantage of the 285s would be looks.
