I replaced the rear Advan sports 245-45-18 on my base 2013 Z with Bridgestone RE 760 tires. The fronts are still the stock Advans. Rear grip is good but the cornering response feels “rubbery” for lack of a better term compared to the stock Advan sport. Rear camber is set at -1.5 degrees. Rear toe in is 0.100”. At highway speeds the front tires turn in precisely as before, but the rear doesn’t generate equal cornering force until after a slight delay. That makes the car feel more and more unstable (twitchy) as speed increases. I guess that means the RE760’s need more slip angle than the Advans to generate the same cornering force. Is this caused by the rear suspension setting or should I change tires?

My tire dealer has agreed to give full credit for the RE760’s against a move to an upgraded tire. So I am now looking at Michelin pilot super sport to get that precise cornering feel on the rears. How are the S04’s with respect to precise cornering response?
