i noticed yesterday while driving that if im cruising at any given speed the car feels like a slightly warped brake rotor does during braking. it only happens when i am maintaining the speed, so it doesn't occur during acceleration or braking.
i tried swapping wheels and it still occurs. the alignment is fine because i got that done 2 weeks ago.

any thoughts or suggestions to what it might be?

 

did you just move your wheels to different positions or put on a different set?

if you kept the same ones on, they could be out of balance or a bent rim maybe?

 

Which side does it pull to and do you notice it on other roads too? I ask because some roads have a higher slope from center for water runoff.

 

different set

always pulls to the right very slightly.
