I have heard 10.5 fit in the back and 295 tires.I've searched all around and i can't find all the specs for the V2's wheels.
What i know
Front: 19x9.0 w/ 255/40-19
Rear: 19x9.5 w/ 285/35-19
Caliper Clearance: ?
Next, i know 20x10.0" wheels fit on the back of the CTS, anyone know or heard of someone that has wheels wider than that? Also i think a wider rim on the front won't work, but i am looking for any solid confirmation on this.
