sloppy handling characteristics after tire change

edub370

Ok so i had my tires changed today. I get in the car and start going down the highway and it feels like I'm driving a 70's Buick. Steering response is terrible and the back end feels unstable. I went from having 274/35/19 nitto neo gens on the rear and 245/40/19 bridgestones on the front to having the same size nittos on the rear, but 245\35\19 nitto Nero gens on the front. I took the car to nissan and they threw some factory nissan wheels and tires on it and it handled better, but sill not as well as i remembered. Can anyone tell me if my neo gens being 5mm smaller up frontcan room my ride that dramatically. I mean my car almost feels unsafe at highway speed and steering its extremely vague. Any help is appreciatedis
