Hi all, I'm just doing some research for my summer tires and rims.
Does any of you think a 275/30R20 tire will fit on a 20X9 rim?
Also will this set up work fine on the 2007 G35S?
Think about getting Vossen VVS-CV2.
Thanks

 

It's a bit wide for a 9 but it's doable. You won't get all of the 275mm on the ground due to the width of the wheel. The setup should be fine depending on the offset. I will say it's gonna look stupid though. You will have a ton of tire buldge. I would run a 255/35R20.

 

the thing with running 255 is that i plan on running 245/35R20 on 20X8.5 for the front, this world mean the offset isn't that apparent anymore.
how would that effect the car?

 

+1, 255/35 in the rear will look much better on a 9 than a 275/30.

 

it will fit , just wont look streched .

i prefer proper fitment instead of wrong fitment.

 

yup they will fit had 295 on 9 inch rims and like the way it looked . it was bulged alil but good because will save ur rim

 

So what is the proper fitment for a 9 inch wide wheel?

 

Not everyone wants to stretch a tire in order to run camber for "proper fitment," myself included.

That being said, here's a 275 on a G37C rear wheel:


No bulge or muffin top, pretty much straight up and down, no rim protection to be had.

 

275 is safe for a 9.0 width wheel.


many of the G37 guys do it.

 

I didn't say it wasn't safe but putting a tire that wide on rim that narrow isn't necessarily functional. You're not gonna get all of your 275mm on the ground. A wheel that narrow will pull the shoulder of the 275 tire in taking away from the contact patch. But yes it is safe and it will save your wheel if you're a frequent curb rubber. I would rather have a 275 on a 9.5" or a 10" but that's just me

so why do mustang guys (yes I know bad example) put ridiculously large width tires on narrow wheels?

From what I was told by mustang guys its for better grip patch.

 

If you have more sidewall to work with it's not as bad for say straight line performance perhaps when ran at a lower pressure. But in order to get the most rubber on the ground you want your tires to be square with your wheels. Not stretched and not squeezed but squared. My personal rule of thumb would be make sure your tires are roughly a 1/2" wider than your wheel to account for 1/4" of lip front and rear that is not measured in wheel widths.

 

Aren't you contradicting yourself now?

A 275 on a 10" wheel is by no means "square." I ran a 295 on my 10" wheel on my old mustang, and that was square, similar to the picture I posted. No rim protection at all.

The picture I posted is "square." Anything smaller on the G37C wheel isn't, and can be considered "stretched," IMO.

 

No contradiction. I said I would rather have 9.5 or a 10. I would personally go for the 10 if it were my wheel. And I guess you can argue that "squareness" is in the eye of the beholder. But when you put the numbers on paper 275mm is 10.83" and if you think 10.83" is square on a 9" wheel then that's your opinion. And I also take it that if you think a 275 is "square" on a 9" then I would guess you think a 245 is stretched? Which in turn would mean you think Infiniti is selling coupes with a factory stretched tire setup? IMO the pic you posted shows the tread curling in as the tire is a little wide for the wheel for an optimal contact patch. This is just my opinion and if you choose to disagree that's fine. No disrespect to your opinion. Different strokes for different folks.
