Rear: 18x9.5 275/35R18

Bolt Patter: ?

Rear Offset: ?

Does anyone know if I could get a set of 18x10.5" wheels w/ a 315/30R18 tire to fit in the rear and what kind of offset I would need so it doesn't stick out farther than stock (or very near so). Could a set of 18x9.5" w/ a 275/35R18 tire fit in the front w/ stock offset and not rub?

I would go out and do the measurements myself, but I'm in the Navy out to sea right now so doing that would be difficult. Thanks in advance.
Any further update on this?

I'm taking my 275/35/r18s off the back and installing them on my front wheels (9") and buying a set of 295/35/r18s and installing them on my rear wheels (9.5"). A buddy of mine with a CTS-V did exactly the same on his 9" and 9.5" wheels.
