Offsets should be in the high teens to mid 20s, you don't want anything higher. Attend a few meets and see what our members run on their coupes/sedans, don't be afraid to ask questions and learn. Tire pressure sensor are just like valve stems and can be moved from one set of wheels to the next! Good Luck!

Thanks for the input Gary. I have definitely been looking around. Unfortunately haven't had much like in the private classified section.

Without knowing what you really want/need, anyone can suggest something, but no one can really answer your question to YOUR best interest.

There are many threads here about tire recommendations. If you want specific to 19", you might try looking more over here too: http://www.myg37.com/forums/brakes-s...and-tires-305/


One last thought comes to mind about your changing your wheels/tires: Are you aware that you will need to address your TPMS sensors/system issues when you make the changeover?
Hey vqsmile,

I think I've landed on a set of wheels and tires that are as such:

Wheels:
(4) 19x8 non-staggered

Tires:
(4) 255/40

Thoughts on that setup?

Well, it will work, but definitely not well. The problem is the rim width. That tire size has an intended rim width of 9", within an overall designed range of 8.5" to 10". You CAN mount that size tire onto that 8" rim size. but they will suffer diminished performance, both in handling performance and treadlife. Notice that the stock G37 Sport staggered 19" wheels are a full 9" in the rear (8.5" in front ), and that's even with only running a (narrower) 245/40.

On the bright side, the overall diameter is spot on for your car.


I would suggest either wider rims, or much narrower tires.

So you'd recommend that I find a wheel with a width of at least 9" but no more than 10"? I can totally do that. I like the size of those tires, so I think find a wider wheel would be the way to go.

Do you have any recommended wheels and/or brands to take a look at in those dimensions? I've been looking at wheels with a silver/hyper silver finish and a mirrored lip. Multiple spokes, similar to the setup of the 07 G35 OEM wheels.

I found these wheels:

TSW Snetterton 19x9.5 Hyper Silver 5-114
+40 Offset, 2.75" Mirror Cut Lip

Those also come in a +20 offset

Well, I guess you can pick a tire size and then select the rims to fit them. I guess I just always figured doing it the other way around; sort of like finding a shoe size to fit your foot instead of changing your feet to make them fit a shoe size you like. No matter though; it will work just fine that way too.

As far as rim suggestion, I haven't really got one. By nature, it is (AGAIN) a very subjective thing. To use the clothing analogy, it's like asking you what style clothes do you think I should wear.

I really suggest you look at a buzillion pictures in as many threads as you can find (here's one: https://g35driver.com/forums/media-s...rket-rims.html and here's a whole library af threads with pics: https://g35driver.com/forums/media-share-v36-sedan-245/ ) until you are sure what you want. Also considering: what will fit, what is well made, what you can afford, etc.
Another place to consider looking for ideas (and deals) is the in the classified listings: https://g35driver.com/forums/19-inch-304/

Also consider looking through the threads over on MYG37.com

I totally follow you. I guess my question at this point is around sizing.

If I want 19 inch wheels, non-staggered, without losing performance and handling what would be the optimal wheel (width) and tire size.

I mentioned the 19x9.5" on all 4, but I believe that size wheel with a 255/40 tire won't fit the front. Maybe a 19x8.5 or 19x9 would fit better. I like the size of the 255/40 but It's not a requirement of mine. I've just seen many others use that tire size for a non-staggered setup.

Sorry, wasn't trying to get your advice on what kind of wheel aesthically. I can certainly do that. Haha. Just need guideance in sizing.

Nate, I'm not sure if you're aware that even specifying a size is somewhat an esthetic choice. The width of the wheel, along with its offset, become a function of the overall equation of how the wheels fit the car. Anymore, it seems everyone is all concerned about how flush their wheels are; god forbid they look sunken into their wells; gotta be hellaflush and all that . . . AND, in addition to that, there is the consideration of what suspension configuration you will be running. Do you have any plans to drop/ lower the suspension? If you do, that also plays a role in proper fitment for a given rim. That being said, I can't imagine that a 9" width is not acceptable in the front, given the appropriate offset, although I have never personally verified it, so take that with a grain of salt. The rears should accomodate a 9" wheels with ease. Certainly an 8-1/2" wheel will be even easier, but your 255 tires would be happier on the 9's.

I'm not too picky about how flush the wheel is with the car. I imagine as long as it fits it should be fine. And at this time, I have no plans to lower. The car is currently stock. Just looking for new wheels and tires without effecting the performance and/or handling of the vehicle. I'll have to do some more research on the 9" wheel width on the front. I appreciate all your feedback with this. It is extremely helpful!

So after doing some even more research and looking at prices online and through the vendor classifieds. I've decided to stay with staggered wheels. Here is what I'm thinking.

Front
19x8 +40
245/40/19

Rear
19x9.5 +40
275/35/19

Thoughts on that setup?

That setup sounds fine. Here's a thread with pics of similar wheel spec (for the rears at least, the fronts are a tad more agressive than yours) on stock (Sport) suspension: https://g35driver.com/forums/v36-bra...35s-sedan.html


Have you considered the pricing and avalability of tires available in those sizes though? : http://www.tirerack.com/tires/TireSe...earDiameter=19
Not exactly the largest selection, or most affordable, but it is definitely do-able.

Thanks for sharing that link to the stock G35s! Super helpful. I actually think it looks just fine on stock suspension. More so than I thought it would. And I'm thinking I'll find a setup similar to his with 19x8.5 and 19x9.5. Seems to be the common setup.

So I've come across these:

http://www.carid.com/verde-wheels/pa...d-1115568.html

With this setup:

19x8.5 +38
19x9.5 +38

With Hankook V12 tires:
245/40/19
275/35/19

Thoughts on that setup vqsmile?

Nate, all I can say is that it's probably ok, but I can't say for certain since I've never measured it out for myself. That setup is just 2mm more agressive than the link I noted before, so it would seem to be ok, but it's definitely getting close to that fender lip, and I really don't want to steer you wrong. I WOULD LOVE IT IF SOMEBODY ELSE COULD CHIME IN with direct experience on similar wheel offsets. Additionally, you know I will make no call as to asthetics, but completely aside for that, I will say I know absolutely nothing about that particular wheel brand or model, so I am of zero help there. Overall, my guess is that, as a package, it would be ok, but I really want for you to get an additional confirmation.

I definitely would love to hear from others who may have experience with this setup for sure. I understand you're not the end all resource here. You just happen to be the only member helping, which I very much appreciate. Please don't feel like I'm basing my decision solely off of this convo.
