Going from 285/35/18 sumitomos to 315/36/17 et streets, and the first place the car is going after the switch is to have my stifflers fit system installed. Should feel like a new car
I have the same tire and I also switched from crappy sumittomos that spun in 4th gear and mine now hooks in first once warmed a bit and hooks 2nd every time. LOVE this tire, good choice!
