Thats not what ovalisation is.
hahahahahahahahaha
That made my night.
On the real, ovalisation is when the bearing slots stretch, causing your bearings to sit in the wheel loosely, making your scooter less dialed, your wheels are probably dehubbing, the squeak is the air getting pushed out from between the PU and the core, I've been riding my gripper like that for over a year now, just don't worry about it.
