This is a 265/30 on a 19x11 hope it helps a little

 

not a fan of that look^

 

My Work Meisters that I ordered 2 weeks ago are going to be 19x10 / 19x11 -7ET all around...on 225/35 & 245/35 Falken FK452.

 

Way to contibute!

I still dont see how people associate tire width with traction. Even modded NA Z's barely put down 300hp but that seems to require a 305+ tire. Most Z's with aggressive fitment have so much camber less than half the tire is in contact anyway. either nissan was stupid to put a 245 rear tire stock or some people just cant admit to having poor driving skills... Hmmm...

 

ok this is your answer...

before u select anything.. ! OFFSET IS EVERYTHING <!!!

this webpage has a picture of each tire and rims size and the tire on it ..
then u can see what the tire will look like ie how much of a strech..

a search . 2003 - 2009 350z and it will give u pics and data sheets of cars with actual fittiments.. of there rims and tires.. offsets...

your welcome

 

From what you've stated, I would lean towards 255 and 285.
