Yeah, your combo is over 3% different diameter front to back. Do NOT drive your car anymore until you get this taken care of. Might have to rent a car for a couple days but will be cheaper than replacing your AWD setup.
You could keep your front tires and run a 265/30/20 in back (0.23% variance), a 255/30 in back will be 0.68% off, or get all new tires if you have room at the fender (which it looks pretty tight) a 235/35 front 275/30 rear will get you to 0.07% difference.
You need to have that variance under 1%, and well under 1% is much better!

 

I would take Brad's advice on this one. This is the only reason I decided to stay clear of staggered setup on a AWD G setup, I'm sure it's been done successfully multiple times, but I worry about if the tires begin to wear that it will again knock the AWD sensors into blinking mode.

 

looking for some insight on what wheel size to run.

I know I want to end up with the Niche Sport M130 Targa wheels. I'm just not sure on what size will fit.

These are going on a 2008 G37 coupe with a stock ride height.

I want these in a 20" rim but will a 20 x 10 fit front and back? If they will fit in the front but not the back, what size could I fit up front? I'm OK with running a staggered setup, concave does not have to match front to back either.

They will fit front and back but choose an offset in the 30s for the front and lower in the rear or find a 9.5 front/10.5 rear

 

Any suggestions on where to order the,? That wheelfire.com site looks like total **** and is not easy to navigate IMO

 

If you're set on 20s, I recommend going with a different brand wheel...Niche is rather cheap and not good quality. Yes, others run them fine and some never have issues, but not worth the risk.
An easy upgrade and getting super affordable would be a set of GTR stocks...CBAs can be had under 1k and DBAs just a little over.

TONS of folks selling their stocks on here for stupid cheap, made by Rays and forged which means quality and even lighter than Niche.

 

Thanks, I appreciate that input and I'll look into them before I buy anything. I probably won't pull the trigger on something until August or September

This car isn't going to be about performance, its really just about looks. Its my wife's car and she is about to get something new so this will be what she takes to the car shows with me.

On the front i was going to get a 20x8.5 and on the back 20 x 10.5. What offsets would you recommend?

 

Try to find a 9.5 up front offset in the 30s, 10.5 rear you can get away with upper 20s in offset

 

Thanks for the help bro!! Much appreciated as I got all 4 new tires. I ran the 235/35 front and 275/30 rear. No rub due to the suspension set up I have. Looks better as well. I'll post pics as soon as I give it an altitude adjustment lol.

 

I'm looking to purchase a 2014 AWD Q60S, and I currently have 20x9 +30 TSW Sochi rims on my 2010 G37x coupe. Will I have brake clearance issues with the larger brakes?

 

No issues but are you intending to run square setup on RWD or changing the tire sizes?

 

Since you have the wheels on hand you can use these templates to confirm fit

Hi there, I'm looking to getting a set of wheels from Vordoven for my 08 G37 coupe Journey. Specs I'm looking at is 19x9.5 +22 in the front and 19x10.5 +12 in the rear. But is it possible to run 19x9.5 +22 all around? And what tire sizes would I need to use so that I wouldn't be rubbing. Im on stock 18's and stock height right now but will be purchasing coilovers once I order wheels.

 

Why do you want a square set up?

 

They're actually out of stock on the 10.5 size, so I was playing with the idea of running a squared set up..lol
