Or just read the back of the wheel. It should have the specifications stamped in there.

 

this information i showed is what is stamped in the back.

so i looked at the back, and though the rear 30 offset is suppose to be smaller.. it comes more inside than the other...
its weird, because if u look closely, u can see the one on the right (Rear 30offset) comes in deeper than the front (43 offset)
any clues?

 

Just click your heels 3 times and say "there's no place like home, there's no place like home"

 

^^^ LOLOL! Sorry, OP...

That would actually be correct, if it is a 30 offset, it will be closer to the centerline of the wheel than the 45. The question is, why is it that offset when according to most sources, the offsets should be very similar, only about 3mm difference between front and rear.

Maybe check on myG37 for more info as well.

 

this whole thread is full of confusion and misunderstandings...

I dont understand why some people never bother to do the research BEFORE you buy.



but to answer your TIRE question get the 245/40/19 all around and call it a day.

the wheel offset is NOT the question you asked so we shouldn't be worried with that one. Put them on and if they works it works. at +30 or +45/48 you should be able to put them on.

 

lol i understand that, just i guess everyone wanted to know why it was different offset.. if it fits it fits, i know that, if i need spacer.. then i will need spacers.

 

.........................

at +43 you wont need a spacer with your setup.

and +30 you definitely wont need a spacer....

I don't know why you dont believe us, it's +45 man.

 

i do believe that it should be 45... but i dont understand why they are 30...

 

+1, especially if you are AWD.

 

That's what they use on the G37's.

You want 225/40F 245/40R or 245/40 all around since you're not dropped too much.

 

after reading this thread, I have gone crosseyed.....

 

it happens

 

The starting point to answer the offset question is: Where did you get them? Are they straight off a G37? As you've said, it doesn't really matter, they can be made to fit and will look great.

 

This thread is so full of facepalm I cant believe it.

Have you actually measured the rear offsets for yourself? Just because it it 'comes more inside than the other...' doesnt mean much due to the fact the wheels are different widths.

As for tire sizes, copy Swivel. 245/35 255/35.

 

Thats what i did when i had coupe 19s
