Current setup: Emotions CR Kai, 17x7front and 17x8rear. 47 offset all around.

Want to run Azenis RT-615's, 225/45R17 in the front and 255/40R17. This is already a pretty agressive fitment when checking with the wheel fitment guide. I've searched and it seems some people have run this size without rubbing, but they were with other tires. I heard RT-615's run a bit wider, so anybody with experience in this combo, please chip and and let me know if it ran ok.

Currently dropped about 1" all around on Koni Yellows with Ground Contols (400lbs in front and 350lbs in rear).

 

I would run a 215 on a 7" rim IMO.

 

How about the rear?

 

Go 245 on the rear to be safe.

 

Running 245's in the back right now...but want to run a fatter rear tire. If I rolled the rears, you think that would be safe?

 

Morning bump. Any other opinions?

 

I would run the 245s also. Same sizes as the stock AP2s, so everything would be fine.

 

I believe Falken shows a minimum of 8.5 in rim width for the 255, preferably 9 in. Also, with a +47 offset you may be rubbing with a 255 (even at stock ride height).
I'm running the 255/40/17 on my AP1 with SSR +62 (8.5 x 17 in) wheels with about 1/2 in drop. It's snug, but there's still room...and it fits within the fender wall. 15 mm further out I'm not sure...

 

That would actually be about 9mm wider out. I would get the 245s and call it a day. :0

 

255 is do-able but your tire guy will hate you haha. Its a little too big got an 8"

215 up front though
