I have searched and cannot seem to find valid information on doing a 19"x8.5 rim with a +35 offset, squared setup on a AWD IS350 F Sport. Will the computer throw any errors for the different sizing if I go with a squared wheel setup? Will a 245 rub or 235's be the biggest I can go?

Im planning on running 19" Vertini RFS 1.8 with 19"x8.5" with a +35mm offset all around with a 235 or 245 35 19 Pirelli P Zero summer tire. I have stock springs on it still.

Ive send IM's to others with no reply...can any one verify that this will be ok on my car?

 

The system looks for a difference in rotational speed between the front and rear wheels. Since a square setup has the same size front and rear, no speed difference will be seen, and no error reported.
