I purchased a new front tire Kenda K657 challenger 100/90/18 for my bike. The tube was reused. The place I had mount it used beads to balance the tire. When I went for a ride there was a lot of up/down movement in the handlebars around 30 to 40 mph like the wheel is out of round. When I got home I raised the front wheel off the ground and spun the wheel. Then I lowered the jack slowly until the tire just touched the ground. It is touching on 1/3 of the diameter and not on the other side. It seems around the valve stem is the worst. When I looked at the bead seam line along the edge of the tire just above the alum mag edge you could see it was out further in that location so I let the air out and pushed the tire in at that area then reinflated it. The gap was smaller but the out of round still exists. I wonder if the new tire is out of round or the mag? I know this bike has some front end damage as I am still working to correct the crooked steering (upper triple tree plate is due in today!)When I spot a reference point to the mag lip it doesn’t seem it is that bad. I called the place where I had it mounted and he will put it back on the machine on Monday. I would think the machine should catch this condition? I am also thinking it’s either the tire itself is defective or the mag is bent, there really isn’t anything else that could cause this, correct?
