    Here's a hint: start by searching wheel sizes of the various models.

    My guess is GM couldn't find an all-season tire set-up in those sizes. You can get them on the sedan/wagon because they're the same size on all 4 corners. You get Goodyear RSA2s.

    The performance(summer)tire and wheel package on the coupe rotate equally front and rear. On the stock 18'' tire and wheel package on the AWD coupe the front wheels rotate 4 times more per mile than the rear. Now can you run the 19'' performance tire and wheels on the AWD coupe without adverse effects? I'm sure its been done. And can you run the CTS V tire and wheel package where the rear tires rotate app. 4 times more per mile than the front. Any adverse effects with that setup? Anyone who has done either setup can you reply?

    Yes you can. The staggered 19" setup the RWD Coupe rotate equally front and rear as you stated. If you look at the sedan/wagon, they run the same tire size all the way around, so they rotate equally as well.

    My father runs the factory staggered 19" summer tires on his AWD coupe without any issues.

    I was wondering the same....any other feedback on this??? I want a nicer wheel on my car and I like the stock 19 inch caddy wheel because the 18's on my AWD coupe are fugly. Also if i was to go to a discount tire to get an aftermarket 19inch wheel and tire would they know the proper wheels being that there is the front tire vs back tire rotation disconnect??

    I sold my stock performance wheels to a guy in MI who runs them on a AWD. I think people buy AWD cars for traction in snow conditions, so if you put summer tires on this time of year they will be useless. Why not run your 18's this winter and have another set ready for spring?

    So can the CTS V coupe wheels and tires be run on the AWD coupe without problems. Anyone running this setup?

    I ran the V wheels with my perforamce tires for awhile. The performance summer tires have the same dia front and rear [245/275]. The 275's on a 10" wheel are a little small but work. Now I have Invo [255/285] tires, same size as the V coupe. These are not equal dia and I'm not sure about using on a AWD. Mine is RWD.
