Tire bulging

Hey All, Does anyone know of a sure fire way to keep a tire from bulging while being inflated with a floor pump?  I seem to have an issue with bulging in one spot of my tires.  These are the tires at 35mm, https://www.continental-tires.com/bicycle/tires/cross-tires/cross-king-cx  I have two tires at that size that bulge.  The 32mm ones do not bulge.  The bulge is not huge, but is noticeable when eyeing it.  Any ideas?  Thanks!

That wheel is definitely not round, look at the inside of the rim against the furniture in the background. Get it trued I tell ye!

Hard to tell from the video but I wonder if the bulge coincides with the valve?  If so your tyre is not seated properly and needs deflating and manipulating into the rim.  Try easing the valve back into the body of the tyre to make room for the edges of the tyre to seat.

 

 

(When this happens to me I ignore my own advice and just wait.  After a few miles things will have sorted themselves out with no help from me, although I will still take credit for fixing it.)

I agree with Spangly - looks like the wheel rather than the tyre.

Try getting the wheel trued first, maybe then the 'bulge' will disappear all on its own.
