Hi, I own a 2006 g35 coupe and need help with the fitment! I want to run 18”s and want my tires to look flush with the body and rims to have a little lip just don’t know what tire size and rim size, offset and p.c.d ? not too sure if this matters but i’m looking at running tien z street coilovers since i don’t really want to lower it that much.

 

There is lot of info on here that can help you with this, but I/we need more info.

I believe all 2006 G35 coupe's come with 19's. Not sure why you're set on 18's, but that's your call. A small portion of people run 20's here. I use 17's for winter. Choose tires with a similar overall diameter (usually within 3%) and you'll avoid most VDC/ABS issues.

If your goal is a flush look, that's mainly determined by the rims offset or the use of spacers (spacers are a VERY distant plan B... get rims with the correct offset if you can).

What's the offset of the rims you have or the offset options on the rims you want? How wide do you want to go with tires F/R? Will you get a camber kit? Do you want to roll fenders?
