Off or not, I don't see a difference nor will many others. I'm not too rough driving corners and so on but it does kick in when I turn sometimes.

 

Why didn't you go with 285/25 or 295/25 in the rears? 285/25 shouldn't rub in the back and your tire sizes would all be stock diameter.

 

Not sure why I didn't. Actually I just looked up the price, for a 285/25 its around $300 and the 275/30 is around $225 or so. Big price difference when you are getting 2 of them. lol, but really...

Just looked it up again and the over all diameter of the stock wheel is 26.68 inches.
245/35 = 26.75"
275/30 = 26.49"
285/25 = 25.61"
295/25 = 25.80"

Sooo... that would mean that the 245/35 is closest, followed by the 275/30. But then again for the front I am running 245/30 so that means I am running a smaller diameter overall but its not a problem to me. I don't mind losing the extra "comfort" with the 245/30 tire. As long as you stay within the 3% bracket of the stock tire, you should be fine.

Gotta pay to play.

 

Actually, the stock rolling diameter is approx. 25.9" if using a 245/40/18 or 225/50/17.

 

245/30 is the closest tire size to stock you can put on the car. @85/25 is the closest to that but its a hair smaller in diameter than stock. That to me look weird, even if its by a hair. I can still notice. You can try 235/35 with a 275/30 Thats pretty close match, but good luck trying to find tires in that size. Kind of a random size in the 20". They do make them commonly in the 19" for the 235/35
