I know, its been asked to death. And I've search but am not getting a good answer. I did find a thread with some good info, but conflicting tire sizes.

I have always wanted V rims. I have a chance to get them

2012 V Coupe
2011 CTS4 Coupe


What I am confused about is what tires to go with

The OEM tire size on the 19's for the AWD is 245/45/19 and 275/40/19 (I didn't think the Coupe AWD came with 19's as an option but it shows up everywhere) which is also the size a few people recommended getting.

This is a .5mph Bias to the rear tire, almost 50/50



The OEM tire size for 18s on an AWD Coupe is 235/50/18 and 265/45/18

This is a 4 Bias to the Front wheels.



Another size that was mentioned was 245/40/19 and 285/35/19

This is a 3.5 Bias to the Front wheels.

I never did get a straight answer on which one was the better choice, but I am leaning towards what Cadillac uses on the Coupes Stock 19's even though there is no FWD Bias. which is the 245/45 and 275/40.

I also like that it shares almost the exact same Diameter as the stock 18's.

If someone can link me to a thread with a solid answer or has the info for me I would appreciate it.

I'd appreciate a reply to this as well!

Buy 4 wheels for the front of a CTS V. They will all be the same size so you can use all the same size tires all around. Problem solved.

This is a really good question. I've been looking for an actual answer to this for about a month.

Madcabbie: Thank you for posting this and providing the detailed information you did. Hopefully someone will chime in if this is possible without the potential of damaging components of the drivetrain.
