Is it possible to fit 21 inch wheel in the back?

 

Hell no!

 

i agree, 19's tops for the G

 

I'll step it up and say, the sky is the limit. It's your G and you can do whatever you want with it. I'm waiting for my 20s to be made.

actually 20's look better than 19's. i'm not too sure about 21's though it may be overkill.

 

IMO, 21" rear rims would look a little cartoonish.

 

Nah... 20 is fine, I actually got 19" right now and feel it's still too small lol

 

i think it might fit aslong as you have measure before ordering the wheel just to make sure you got enough room. i got 20's and i think they are still kinda small. i wanted 21's in the back in the first place but i dont want to wait a few months just to get tires in that size

 

I just say, SEDAN YES, with a nice bodykit from the dealer. 21 inch yes not a coupe!!!

 

why not just go a head and put 24s on while ur at it. That is a lot of rotinal mass with 21 or 20 for that matter. I would not excede 20 inches but its ur car so u can do what ever floats ur boat.

Good luck and let us know how it goes

 

Had 18s - way too small
Had 19s - too small
Have 20s - perfect
21s - too big
22s - looks like a joke

 

Well, the stock (215/55R17) tire diameter is 26.3 inches. I suppose if you can find a tire with a low-enough profile to stay reasonably close, then yes. Of course, at some point, you might as well just stretch a rubber band around the rim for all the rubber you'll be putting on between it and the road....

Unless you guys running these monster wheels are also going with light weight wheels (or at least as light weight as the factory wheels/tires) you'll be losing performance and ride quality. For me, I'm planning on going with a light weight 19" wheel/tire combo to improve performance as well as looks. If all you care about is looks then go with whatever fits (its your car - do what you please), but don't be surprised if performance (which includes braking) and ride quality suffers.

Personally, I think 19.5's would be perfect, but obviously they don't make rims that size and tires.
