Whatever tire you go with, make sure the tire store has a road force balancer, and they really know how to use it. Have your tires road force balanced. It costs more for the service (about 100 or so per set in the US) but, doing it eliminates the chance of a bad tire, vibrations from tires, tells you if a rim is bad etc... GM mandated all dealers to get this technology to avoid tire/wheel issues causing vibrations. Ski
