Hi there. I am a newbie with this wheel talk. I'm looking into getting on some new wheels in the spring here and not sure about the width and offset on some TSW Nurburgring wheels.

I have a 2010 G37x sedan with 17" and non sport.

I want a square set up so which size should i be getting?

19x8.5 +45
19x9 +32
19x9.5 +41

What differences would these sizes have on the car?

tire size i'm looking at is 245/40/19. What width best fits my car and these tires?

Thanks in advance for the help

 

If you're not lowered or plan on lowering the 8.5 +45 will work fine.
Tire size is perfect for those rims too

If you want a flush & square setup the offsets will have to be more aggressive, somewhere in the mid 30s. Same if you're lowered.
