Hi
not sure if it's about the tire or something wrong with fitment.
i had potenza S0001 replaced.
got my new apex EC-7
front: 18x9 ET42
rear: 18x9.5 ET43
i equipped all tires with 245/40/18 *Toyo R888*.
the car is vibrating while moving from 20-35mph.
moving from 0-20mph && from 40mph++ is fine and there is no vibration.
