Hello everyone..
I have an 09 G37 sedan that I'm about to put some 20's on, but I'd like to know what size tires you all would recommend putting on them before I do. The Set I am looking to buy comes with,
20x8 Chrome 5x100 & 5x4.5 +40 Rims & Delinte D7 Thunder 225/30/20 tires.

but I wasn't sure how they would fit considering I'm ordering them from the internet. Any input would be greatly appreciated.

Thanks

Not sure what the 5x100 is, but the 5x4.5 is correct, can also be listed as 114.3mm. Those wheels and ofsets will fit fine. If I were to upgrade to 20s I'd put at least 8.5" wheels and run 245/35/20 +35 to +40. Those Delinte tires are real cheap, not sure that's the place I'd be trying to save money. Name brand tires don't cost that much more and they really are 4 of the most important parts on your car, just sayin.... You might be able to find some better deals in the marketplace on this site, if you haven't checked it out I would

 

Your G has a 5-114 bolt pattern, but if the wheel is a 5x100 then that's not going to work. Looks like you're listing two bolt pattern. Are they a dual bolt pattern? Tire size is way small for the car. Smallest I would suggest is 245/35-20 to keep load and diameter correct.

 

If I were you I would do a little more research on wheels and tires before you spend money on something you wont be happy with. If its a 5x114.3 it will work but with those specs and tires the look is not going to be what you want. Wheels and tires are a large expense so do not rush it.

If your set on 20s check out fitments around 20x8.5 - 9 and 20x9.5 - 10. A staggered setup will look a lot better on your G.

And with 20s your G will look lifted if you don't lower it. So then lowering springs or coilovers may be needed.
