Cadillac CTS-V - best tire size when lowered

Hey guys I have a 2004 v and I'm looking at lowering the car with h&r springs and getting new tires so I'm wanting to know what sizes are my best options.
The sizes I'm looking at getting are
275 40 18 rear 245 45 18 front
275 35 18 rear 245 40 18 front
245 40 18 front and rear
Or just the stock size

Thank you,
Evan

I had the stock size and thought the sidewall looked too fat. So I dropped it down a profile and run 245/40 18 front and 275/35 18 rear. I have no issues at all.

I've got the Eibach springs.

i just threw 275/40 18's on the rear with 245/45 18's on the front lowered with the eibach kit and not rubbing at all

i run nitto invos on forged staggered wheels

I have to say that I honestly don't think I have ever seen a 20 series tire.... I mean up close....I have seem some on "DONK" rides that didn't even look like that they could hold air.

Cant go wrong with Invos. They are a great tire.

I would have to agree with this! The lower side walls look perfect with the Eibach springs.

I run stock sized gsd3s on my car with H&Rs, my avatar is my car.
