Iím installing 275/35/19 and 305/30/19 on my stock wheels on my 2012 CTS V Coupe. I understand spacers are recommended. I note I can get 11 mm for the front and 15 mm for the back. Some suggest running 15 mm all the way around.
I do not drag race the car. Rather, I take it to driving schools. Obviously, Iím looking for road course handling.
Any suggestions would be greatly appreciated.
Thanks so much,
