I am about to replace the OEM rims with 370Z Rims, Front (19x9) offset 47 Rear (19x10) Offset 30.

Here is my tire setup for the 370z rims (245/40/19 and 285/30/19)

As for the Rear, would they rub with this setup: 285/30/19?

Also

Would I need Spacers for the Front?

Are you dropped? The rears are coupe offsets and are pretty aggressive for the sedan. I'm running 295s on 20x10 +45 dropped to zero gap (stock camber specs) and I'm about 2mm inside the fender roll. It would be ideal if you could find 4 front Z wheels and use spacers if needed. I'm afraid you'll need to camber in, go stretched, slammed, or a combo of the three.

No i am not dropped.

Matter of fact i am going with 245/40/19 with a hr 15mm spacer and in the rear i'm going to perhaps need a camber kit as i run 275/35/19 setup.

What u think?

won't you have issues with the AWD system running that setup? I thought it was a 3% difference in width and you'd be ok, seems like you'd be running much more than that...

What you mean???? When you changing tire sizes you've to stay within 3% of the diameter of the Original Tire.

This setup yields a results less than 3% percent of that. 1.57% < 3%

My Front Diameter Variance: -0.53% (245/40/19) and the Rear Diameter Variance is: -1.04% (275/35/19)

It's the diameter difference from oem to the new tire size that needs to be within 3%, width won't cause issues (except for fender clearance )

OP, take a look at my setup and add 15mm to the outside wheel clearance, plus not being dropped your wheel will be a few more mm outward. It'll be poking out a good 3/4", even w/ 275s.
You won't need a camber kit if your staying at stock height.

Thanks for Chiming in blnewt and enlighten the community on how to properly conduct a staggered setup.

I am going to add a 15mm HR spacer to the front. I don't think I am going to dropping the car at least for now.

After this project blnewt it will be time to move on to my Twin SC project.

Twin SC, count me in for pics
Here's the fit you can expect in the back w/ those Z wheels, looks like his fronts are +20 offset, which seems more in line w/ Z wheels. Keep in mind w/out being dropped you'll be poking out a bit more.

My mistake, thanks for educating me . I'll probably get some new wheels in another year or 2, I'll have to make sure and consult with you before my purchase . Your fitment looks great btw!

Thank you very much sir!

Question: I need some All Season Asymmetrical Tires being AWD, What tires would you consider?

Out of curiosity what are the typical offsets required to have rims sit "flush" with the fenders?

+45 front / +35 rear?

(apologies for the side question)

Note: Reason being why it pokes out a bit is that the car shown "rear tires stick out because they have 295/40 tires. 275/35 would be perfect."

My rear setup is 275/35

Don't quote me but the Rear (35) sits very very flush. As for the Front it can be offset with a 15mm or 20mm spacers.

^ok thanks, I meant without the use of spacers (rims in general, not the 370z rims specifically)

Thanks a lot
Hope all is going well w/ your G, haven't seen any updates lately, I'm sure you've got some things brewing though

No problem
I've been very happy w/ my Toyo Proxes4 Plus tires, pretty nice deals on them at Treadepot.com Andrew gets you the best deal if you mention this site BTW.

Rim width also needs to be taken into account, that's why the myG37 wheel calculator is so helpful. A great way to see what works is take your current setup (assuming you know your wheel width and offsets), measuring out from your current wheels/tires to see what flush will be and say it's 20mm, then just start playing w/ that calculator to see what's going to get you there. Or you can just ask around in the wheel/tire section of the site. It's a bit more rewarding finding out on your own IMO
Also the amount of drop plays a role too, what would be flush at stock height will be further inside the wells when lowered. A 10" rim at +45 is pretty flush on my dropped G, a +50 would be about the same if I was at stock height.
One of the problems of going to a square & flush setup is the front fender isn't rolled like the rear so if you're pretty low you'll have rather significant clearance issues in the front. I've had my G lower and w/ my old wheels I had the fronts spaced to about 4 mm from the edge and I was rubbing that inner fender edge all the time. That's why my current front setup is about 8mm inside. For reference my wheels are 8.5x20 +40 w/ 245/35/20 and 10x20 +45 w/ 29530/20, no rubbing anywhere and almost flush in the back.
