Vibrating between 40 and 70 mph

My 2017 corolla LE has 56k miles now. I can feel a little vibration than normal when it's cruising between 40 to 70 mph.

Is it due to front suspension?
Or belt tensioner?
Don`t know if that will fix the vibration, it might . Be sure they do a balance on the wheels when you get new tires . Let us know if thar stopped the vibration problem.
