I own an X Sedan and I need help with tire size for 19x8.5 35mm and 19x10 40mm staggered setup that will not have any issues with awd system. Any advice or recommendation is greatly appreciated. Thanks.

What about 245/35 and 275/30?
Sorry I'm a newbie on wheel and tires.

Those wheel sizes should fit without a problem, but for better tire performance you should go with 245/40/19 and 275/35/19. With those, you should be good to go!

Correct, 245/40 and 275/35

Anyone here ever run 20x9 +20 / 20x10.5 +25 with 245/35 285/30 tires on a G37x coupe? I have a few questions/concerns about the setup. Firstly, how is the fitment? I know it is really aggressive so I was wondering what needed to be done to get them to fit properly. What kind of camber should I expect to be running? Im sure I need to trim my fender liner. Thanks in advance.

Can almost guarantee the 285 won't work in the back without a bunch of neg camber...I'd go either 255 or 265 to keep the camber under -2


This is with a 255 rear on a 20x10.5 +25

Going to be tough since you're AWD, the widest setup that "might" fit would be a 235/35 275/30 combo and this will keep your variance at almost zero (0.07%)


An easier fit would be 225/35 265/30 for a 0.27% variance.

What are your camber specs with setup, if you don't mind me asking.

Not my ride, but I can find out for ya.

Dennis, I have had numerous sets of wheels and I can gauruntee that you are going to have to pick 2 of 3 to make these wheel sizes fit.

1. Stock fenders (meaning no fender pull)
2. Spec Camber (meaning -2 or better for the rear)
3. Tires that fit the wheel (meaning at least 275 on a 10.5" which is still a light stretch IMO)

I have had the exact tire specs you are asking about (20x9 +20 and 20x10.5 +25) and I was easily rubbing the fender liner on the rear with 255/35R20 tires all around. I am only lowered on Eibach, so we're not even talking slammed. Here is what that fitment looked like with -2 camber in the rear.





As you can probably see, a wider tire would make this fitment even more problematic.

Damn. Mine will really look stretched then. I got 255/40 to go on 19x10.5! I wanna see how they look on the car first before I make the decision to drop or not but Kenny said I will more than likely want the drop. Curious to see this stretch now, but I went with that size because the variance was less than 1% all around. That was as close to stock as I could get

Hopefully you bought quality wheels because I cracked one of those rear wheels in less than a year without hitting any crazy potholes or anything. I suspect the stretched tires didn't help. Also, the lip of the wheel was annihilated from stone chips and not having any protection from the tire. Lesson learned on my part.

I don't have any potholes around here really. I got a set of ESR wheels...they feel solid. Hopefully will get them installed this weekend...we'll see. I'll run this size for now and may bump to 265/35 later if the fit is too stretched for my taste. I bought the tires already so I am stuck for now

Thanks for the input Ryne, I actually follow your build thread and I'm loving your G!

I'm not the biggest fan of stretch, I like to fit a decent amount of tire on the wheel as to not waste it (if you know what I mean). How much neg camber do you suspect I would need to run to make these work? I'm dropped on coils but also not slammed. I'm just trying to see if it would be worth the trouble to try to get these wheels to fit as I'm getting a pretty good deal on them if I decide to go this route. Thanks!

Just keep in mind that you have to keep that Front to Rear diameter very close so that complicates things. If you go w/ Rynes staggered wheels on the same size tire that would be a plan, but staggered tires you really need to plan ahead. Sounds like you're asking the right questions, and a stretch isn't a deal killer as it is better than pinching a tire.

Haha thanks blnewt, just trying to learn something. It's always harder to figure out a setup when you can't physically test it yourself on the car. I was hoping to get the 245/285 setup because if the rolling variance is so miniscule. Plus, if I'm buying new wheels, might as well take this opportunity to upgrade my tires sizes, too.
