I just recently purchased the Avant Garde M310 for my 2008 g35 sedan but i do not know which tire sizes to run so that it wont rub and i wont have to roll my fenders. I am also not looking to lower the car and going to keep the stock suspension

These are the specs of the wheels:

Front: 19 x 8.5 offset +35

Rear: 19x 9.5 offset +40

Some people suggested 225/40/19 in the front and 245/40/19 in rear
Others suggested 225/40/19 in front and 235/40/19 or just 235/40/19 all around

Im so confused on which tire setup would be the best for me. Anyone help me out please!

Thanks in advance!

 

You want the widest stance/tires possible? If so 245/40/19 fronts, 275/35/19 rears. That's the recommended max size (width) wise.

 

Mm so that's the setup for the widest stance huh. I'm not really looking to go that wide. But just a normal fitting if possible. What setup would you suggest for just a normal look and setup ?? Thanks!

 

a 245/40/19 squared set up would go great with the 8.5 and 9.5 and would be practical to rotate, etc.

 

I think he wants a staggered setup though. If you don't want a wide looking stance, then the recommended 225 fron and 245 rear will do.

 

Do you want a slight stretch look to the tires or a vertical sidewall? G37S coupes come with a 225/45/19 on a 19x8.5 up front, and G37S sedans come with a 245/45/18 on a 18x8.5 in the back. This will give you an easy comparison between a 225 and a 245 on an 8.5 rim. The look will carry over to the 19x9.5 rears you have, a 245/40/19 will have the same slight stretch as a 225 up front and a 275/35/19 will have the same vertical sidewall as a 245 up front. Figure out which look you like more.
