The best size for those wheels & AWD would be 235/35/20F 275/30/20 R
this will give you a front to rear variance of only 0.07% or virtually zero, can't do any better than that w/ a staggered fit. The 245/275 combo will be at -0.97% which is under 1% but having the rear tire smaller will result in even more variance as time goes on since the rears wear faster. If you like the rims I'd run them as is but when the time comes for new tires I'd go w/ the 235/275 combo.

That set will fit and clear your floating calipers. If you upgrade to a big brake kit later they might not clear as a lot of bigger wheels don't clear due to design, backspacing, etc.
Here's a template you can use to check big brake clearance if you plan on getting Akebonos later

And here's a handy calculator to check different tire/wheel setups

FWIW big 20" wheels tend to look a bit "off" on vehicles at stock height, the fender gap combined w/ the big diameter rims/thin sidewalls detracts a bit compared to a dropped G w/ big wheels.

 

Wheels arrived! Super happy with how they look! There was rubbing in the rear, but that was fixed by trimming a portion of the fender liner and a portion of the rear bumper bracket.

**Thanks for the help blnewt!!! Pics uploaded correctly

 

Those look great

Recently picked up some coupe wheels. the tires are all 245/40/19. im dropped on swifts and my g37 is a journey. just wanted to make sure im good to go on them fitting or do i need to take any extra steps.. Thanks

 

No issues whatsoever

 

Great thanks im gonna get them balanced but should i gey yhe alignment or can i wait on that?

 

Unless you've lowered your G or jarred a pothole or something else that may have tweaked your alignment you won't need to get one. I would get an alignment every few years though as it never hurts (as long as the shop is competent, lol).

 

Hey guys, 08 G37s lowered on eibach springs, found a set of wheels with the specs below:
19x8.5 +15 / 19x10 +20

Looking for a slight poke front and rear, or very flush. What do you guys think? Also, what tire size?

Not looking for fender mods, or running any weird camber besides the natural camber, I just want to slap em on and go Thanks!

 

If you want to run stretched tires those will work, the rims will be outside the fender but the stretched tires will tuck inside the fender edge. I'm not one to recommend going stretched as it exposes the rim to curb rash and may be hard to claim tire warranties if you have a failure, but that's just my 2cs. Tire sizes like 225 front 245 rear would be about right.

 

Do you think the wheel will poke too much? Any pics I can use as a reference? I tried to search for one but maybe my search skills aren't as great

 

Here's a thread w/ 8.5 +17s on 245s and 10.5 +35 on 265s (the rears will net a +29 if they were 10" wide)

You might want to post your specs on this thread too, the guys in that thread are well versed in very aggressive offsets w/ stretched tire sets

Thanks man I will! I appreciate the references

 

I am on 2010 sport OEM wheels. I believe these are the spec.

Front:
Wheels: 19"x8.5". Cast aluminum. Made for Nissan/Infiniti by Enkei. Weight: 26.5 lbs. Bolt pattern 114.3 x 5 Offset +43

Rear:
Wheels: 19"x9". Cast aluminum. Made for Nissan/Infiniti byEnkei. Weight: 27.5 lbs. Bolt pattern 114.3 x 5. Offset +45

When I bought the car, it came with brand new tires. Front is 245/40/19 and Rear is 285/35/19. Will the tires fit the rear wheels?

Also, I think I can put 20MM spacers in the front with no rubbing? Do I need to put any spacers in the rear? BTW, I am on BC coilovers.

 

You're running a pretty "pinched" mount in the rear running 285s on a 9" rim, it'll fit but the sidewalls will "roll" under hard cornering providing less than optimal performance. I'd run them since you already have them but your next set should be 275/35/19s back there. As far as spacers, that's entirely up to you, if you want a balanced look go w/ your 20mm front and whatever spacer in back to get a similar fit at the fender, probably something in the 10mm range.

 

Alright picked up some new wheels
Rotiform TMB
Fronts - 19x10 et20
Rears - 19x10.5 et48




Now im not too sure what tires i should get. These will be going on a 2014 Infiniti Q50 so fitment should be similar to a G37 sedan.

Local tire shop was saying 245/35 for the front and 255/35 for the rear. I drive my car (canyons once a week) and i think that the sizes they recommend have too much stretch. Any recommendations for tire sizes? Im going more for the fat tire than stretch.
