vibration while decelerating or speeding

Does anyone know what could be causing my 01 IS300 vibrate when i let off the gas pedal when im doing about 65 or faster. Also when im doing about 80 to 100 my car seems to vibrate im wondering if its my tires needing to be rebalanced or is there something common for this issue? fyi i have the stock 17s on it. thanks for your input

mine was like that as well, got wheels and its fine now. But i think it was the balance of the wheel that was off. does it vibrate when u brake? if not then its the wheels/tires/balance of the wheels

if it is affected while you brake, you want to check your brake and rotors. if it is just while you're driving, i suggest you first go to a shop and ask for them to mount and balance your wheels and get a 4 wheel alignment. if the alignment fails, they'll know why and what to do. if it passes, you should be good to go
