Just like the title states, what are the correct tire sizes for the 2011 CTS-V Front and Rear Tire Sizes? I am in the midst of buying a set of Michelins for a set of 19" Chrome CTS-V Wheels and need the correct tire sizes, as these wheels are going to be installed onto a 2009 Pontiac G8 GT. Any and all replies are appreciated. Thanks

 

according to cadillac website CTS-V coupe sizes are F-255/40/WR19; R-285/35/WR19
and the CTS-V sedan uses F-255/40/YR19; R-285/35/YR19.

 

Thanks for the information.
