Tire size options on 19" stock rims
 

Hi,
I need new tires for my G37s coupe and wondering what other size option tires can fit on stock 19" rims? Looking for wider set up.
Thanks

Best bet is to get spacers.

You can run 265/35/19 in the rear and the will give you a nice bit more tire in the rear..

Front you can run 245/40/19.

if youre looking to bring the wheels out a little further than yes, as csnpsu said, spacers are what u want (if you are staying with the stock wheels). getting a wider tire wont accomplish this. if youre looking for a wider tire just for the sake of having a wider tire, i believe most common set up would be 245's front and 275's rear....

275 is to wide for 19x9inch wheel and will through off his speedo and also more side wall you have hanging over the more body roll you will have.

I'm running 245-40-19 front and 275-35-19 rear and I love it. There is no excessive bulging in the sidewall and no noticeable increase in body roll. My speedo is as accurate as it was with the stock setup. I'll try to snap some pics to show you what it looks like it you want...

I'm running 245/40/19 in the front and 275/35/19 in the rear and have no issues.
see here for pics: https://www.myg37.com/forums/3113989-post14.html

Can I have pic of the entire car please :)

You guys don't see it but I do. You want your side wall to be pulled a little .. You look at the 240.40.19. You see the side wall is pulled and fat looking . The 275 looks like it's fat. I would not run a 275 on 9inch wheel.

eibach pro kit
 

what about if i decided to lower it with maybe just the eibach pro kit?

I am on the Eibach pro kit with the sizes i mentioned above.

A 275/35, has the closest diameter to a 245/40, and a 225/45.

Also went with 245/40/19 and 275/35/19 ventus V12 on the stock rims.
I don't see any tire fat, the car just looks massive from behind, and i like that. However, you will need to hold your steering alot more then the stock tires. Wider tires do follow the road with more response, not such a good thing when the roads are in bad shape(ex:montreal).

Btw, the ventus are alot more comfortable a bit less noisy, of course much cheaper then the OEM overrated potenza.

You're the minority as far as that issue is concerned. A 275 on the rear is totally fine and has no sidewalk buldge.

Yeup, I agree. ^. I also want to add to TVPostSound post.
He is correct in stating the 275/35 has the closest diameter to the 245/40. In actuality, with 265/35's your speedo will read 1.5% faster vs. having 275/35's your speedo will only read 0.5% faster hence one of the reasons the majority of the people here go with 275/35 instead of 265/35. I personally went for both the better speedo reading as well as a beefier "rear-end look."

lol

Your telling me your really going to see that..

Actual Speed: 60 mph 100 km/h 245.40.19
Speedometer1: 60.9 mph 101. km/h 265.35.19 Rim Width 9 -10.5
Speedometer1: 60.3 mph 100. km/ 275.35.19 Rim Width 9 - 11

If Nissan wanted us to run a tire that wide they would have made the wheels 19X10.

Your running a tire that can support wheel that 2inchs wider ?
:7:

Call Tirerack they will tell you the same thing.

I think you missed his point. The point isn't that you'll notice the 0.3mph difference in speed. The point is that a 275 on the rear wheel is as close to a "plus zero" size as you can get, while still being safe. And, if you didn't know, the Tire Rack has a rep that posts here and also recommends a 275.

You obviously aren't going to believe anything other than what you want to believe.

Here's a pic of a 275 on the 9" rear wheel, just to show there's no muffin top here:
Attachment 172876

Exactly my point. Additionally, I bought my tires from Tire Rack and they told me to go with 275's not 265's. I even "tested" them and asked if 265's would be better and the rep told me "no." But as san~man stated, "you won't believe anything other than what you want to believe", even though facts are presented to you and prove otherwise.

Oh BTW, concerning the sidewall, which you are worried about, it is actually 0.1 in smaller on a 275/35 setup than a stock tire per the Tire Size Calc.

Lowered?
 

wow nice wheel. is that powder coat or something else?

is this car lowered? how long have you had this wheel/tire set up, i mean is there difference in thread wear compare to stock size?

My issue is your running a tire that much wider then your wheel.

If you look at the 370z sport wheels they are 19X10 on 275.35.19 And the tires are nice and tight and are pulled just a little bit.

Again putting 275. on 9inch wheel is not smart.

But each to it's own.

man, you're the one who mentioned the speedometer in the first post so don't be sarcastic and ask whether we're gonna see the difference or not :5091: It's a matter of fact that 1. the 275/35 has the closest diameter to a 245/40, and 2. as close to a "plus zero" size as you can get, 3. ur last argument was to ask a tire rack rep, and we did and they confirmed our point of view. My friend has 285 in the back and 255 in the front on the stock suspension without any pro kit or anything and it fits perfectly! I started a thread a few days ago asking about different tire brands (https://www.myg37.com/forums/g37-cou...r-my-baby.html) and I was looking to get 245/40 and 265/35 but after reading this thread here i'm now considering 275s instead!! thanks for all the helpful info guys :biggthumpup:

What brand of tyre is that?

Can I run 245/40/19
 

Can I run 245/40/19 all the way around? If so how would this or would this effect the speedo or ride?

Thanks

You're fine running those on all four corners, speedometer won't be affected and ride will be :biggthumpup:

245 front 285 rear with eibach pro kit & 20mm spacers all around. No issues, no fat friends either.

285/35/19?

Yes 285/35/19 Continental dws' in the rear.

245-40-19 275-35-19 Bridgestone so4 850 installed from discount tire

This is kind of related, but I notice with stock tire size on oem 19s that it's slightly difficult to keep the car in a perfectly straight line on the highway. I'm coming from a 06 350z, owned 2 of them, and the steering wheel at dead center felt much more defined, with both 350z running stock 18s staggered with 225/45 and 245/45 tires, all rims half inch narrower than g37 oem 19s. The stock tire size on the g37 seems oddly narrow to me.

Does anyone have any feedback as to whether a slightly plus sized tire, maybe even 245/40/19 all around, would correct the vague dead center feel in the steering wheel? I'll be getting Michelin pilot super sport tires, which I had on my 350z and were totally amazing for anyone curious about that tire.

Have you had it aligned, might be a bit off, and if so it may be wearing the tires in such a way that they're not tracking as well as they should.

Are you running spacers as well? If so, what size?

It's been aligned, and it tracks straight, it's more of a feel thing that I thought could be attributed to the tires seeming a bit stretched and possibly not making as big of a contact patch. I don't actually think anything is wrong suspension wise, it's more of how stable the car feels to the driver.

I know this thread is old, but i can't seem to find an answer to this. A buddy of mine has some lightly used Bridgestones off of a mercedes sl that he's selling for 200. He's a mechanic so i trust him but i need advice. The sizes are 255/35/19 and 285/30/19. Would that setup work on my stock 19" sport wheels? Any help is appreciated, thanks!

That's pushing it on stock wheels

The fronts are a decent fit but the backs would be better on a 9.5" minimum width rim. The mount will be pinched in back which will cause the sidewalls to roll under heavy cornering. The tire won't fly off the rim or anything but your cornering stability will decrease.

If you don't really push the car hard then they'll work. Also keep in mind those sidewalls are a series shorter so the ride will be quite firm, like you're riding on 20s.

Thanks guys. I guess I'll be passing.

My car feels this way as well. Is it the narrow stock 225/45/19's up front ?

Just wondering how low did u drop it? I'm goin wit that tire setup. 245/40/19 front and 275/35/19 rear. Do I have to get spacers for all ? Does it have to be 20 mm spacer and I using my stock rims 19 thanks

I wanna get 245/40 and 275/35 tires on my 19 inch stock rims and wanted to drop it by an 1 inch u think it won't rubber and I wanna put spacers on it how big should I get the spacer.. Anyone has any suggestions I'm pretty new to this thanks

^ that setup wont rub. If you go to big on the spacers though you then may rub. My recommendation is 15 mm rear 5 mm front with 245/275 setup with a 1 inch drop. That gives you a look that is nice and staggered and looks like it came from the factory that way. You can get away with more up front but to me that shows too much front tire tread from certain angles.

Thanks so ur sayin I can drop it 1 inch around but I have to put 5 mm front spacer and 15 in the rear so it won't rub?

Nope... you dont have to put on the spacers to prevent rubbing. In fact without spacers there should be 0 chance of rubbing with that setup unless something is wrong with the suspension. Without spacers the tires will have more space between the tire surface and the wheel well edges. The larger the spacer, the closer the tire gets to the wheel well edge.

But if you want a little more aggressive looking stance without rubbing (based on my experience with a 1 inch drop and spacers) my recommendation was the 15MM rear / 5 mm front spacers. Some people go with larger spacers. But my recommendation, in my opinion gives it more aggression while keeping it looking like it came from the factory that way

if you get spacers that are too big, you will rub.

Thanks is it okay if I see a picture of it

It depends, I'm still on stock suspension and running 245/40 & 275/35 on the OEM sport wheels (they're powder coated metallic black. As for spacers I picked up 20MM for the front and 15MM for the rear.

See the pics, that was when I was test fitting the spacers

wife's 2011 19" wheel convertible needs new tires.
been doing some research
we live in Mississippi so no snow.
I was looking at some all seasons.
car has only 30k+ miles and still has factory tires
BRIDGESTONE
POTENZA RE050A
Front: 225/45R19 92W
Rear: 245/40R19 98W XL


I have been looking at the
BF Goodrich g-FORCE COMP 2 A/S Tire
or the Continental Extreme Contact DWS06 Tire
the bfg's are cheaper but only by about $100 a set
some reviews talk about a high road noise which I don't really want


I see a pretty good deal on DWS06 255/40R19's that I could use in the rear and put 245/40R19 on the front.
actually the rear POTENZA RE050A 245/40R19 98W XL have much more wear left on them and I could just put these on the front.
these are W rated while the DWS06 are Y and tire rack told me it might be better not the have 2 different ratings? any truth?
I would really rather buy a set of 2 for now as the rear probably have at least another 10k left on them.


I would like to try to keep the gas mileage about the same

I was also looking at going to up size and see that
Front: 245/40R19
Rear: 275/35R19
are the most common replacements.
I DO WANT TO ADD SPACERS


This is for the wife so although I might like the look of the wider tires, I don't want to make it harder to steer or drive.
Any suggestions?
Anybody runs these brands (they are fairly new replacing older series w close to the same name) ?
Anybody done the upsize and can tell me what they think?


Also since we are in the back woods state, I was looking at ordering on line.
tire buyer has best price, but reviews are either 1's or 5's
amazon is close to tire rack, gut tire rack offers free road hazard which may make them the most logical choice
fyi for those looking, most offer cash back sites like ebates to save 4 - 6%


thanks.

Nice looking good
I just found rims
Front 19x8.5
Rear 19x9.5
Both at 35 offset

And the other rims is
19x9.5 all around with 38offset
Juss wondering if I can run this setup wit it too like the stock rims. I'm gonna get the rims n tires 245/40 and 275/35 or 265/35 first than drop it with eibach would it still rubbing not gonna put spacers yet any suggestions thanks

If you're running Summer tires now please don't put a pair of All Seasons on the back, not a safe condition. If you want to only buy two tires now and you live in a place where you can run Summers year 'round I'd look for a pair of Summers in the size you want, then get the other pair when the time comes. Some tires getting good reviews would be the Bridgestone SO-4 Pole Position, BFG SportComp2, Conti DW, and the gold standard Michelin Pilot Super SPort. For the price those SO-4s are hard to beat.

If you feel that you'll really need all seasons I would get a complete set of 4.

I see alot of ppl are going 245 on the front and 265 or 275 on the rear.

My question is about different tire profile as i live with bumpy roads and have a bad back.

Instead of going 245 with a 40 series profile, I would want to go a 45 profile on the front.

With the rears instead of going 35 series on the 265, I would want to go a 40 profile.

Yes, i know my speedo will be out (doesn't bother me) but will the looser tire sidewall have any probs with hard cornering ?

thanks

Should be ok in that regard, if you have a RWD it would be less chance of problems vs AWD.
If you are running a softer sidewall touring tire or higher mileage All Season tire the sidewall flex might not be to your liking, but a higher rated summer tire shouldn't be a problem there.

I just looked at Lexus ls460, they run 19x8 with a 245/45/19. Our coupes are 8.5 and 9" wide

G37xs
 

I read through this thread and I would like some input if anyone can help. I have a 2013 coupe xs so its all wheel drive with the 19 inch wheels and I am going to need new tire soon. I want to go a little wider but I also want to keep the same tire size front and rear. I don't want to alter the way the car drives too much and I do not want to ruin my mpg. Any suggestions would be appreciated.

You can run a 245/40/19 without any issues to your AWD or any clearance problems, the diameter is about a 1/4" shorter which is 1% shorter than your current 225/45s. Also that 245/40 is typically more common so you should find a wider variety of tire choices.

Thanks for the info, makes sense to me. One additional question though. Is a 245/40/19 tire a better tire than a 245/45/19 or is it just more common?

Not a better tire, but much closer to your OEM diameter which is best to keep as close as possible to your original tire height. Use this calculator when trying new combos~
https://www.myg37.com/forums/tire_rim_calculator.php
FWIW the 245/45 is about 3/4" taller (about 2.5%) than your 225/45.

Ah alright makes sense, got it. I appreciate the help man.

G37 coupe Sport 2011
 

Need some input on tires and sizing:
I have a 2011 G37 Coupe Sport with offset tires as purchased from Infiniti. Looking at getting same size but increasing rear if possible:
2 G-Max AS-05 Front: 225/45ZR19
2 G-Max AS-05 Rear: 245/40ZR19
OTD would be $720

Would my car be able to use a slighty wider tire:
2 G-Max AS-05 Rear: 255/40ZR19
If so the OTD price would be $746.

Let me know your thoughts, also if General tires have been used by any of you. Prior tires have been OED Michelin Pilot and currently Hankook Ventus V12 evo2.
Thanks in advance.

Ordered wrong size tires will they fit?
