When you spin the tire you will see that it is not round but likely has a bump or is slightly oval. It should be round and not out of shape. Viewed from the side as it rotates it will be noticeable. Do try to spin the tire and view it from the rear too. You may see a bulge on the side of the tire if it is defective.
Give the entire tire a good inspection on both sides where the tire seats to the rim. It should be seated properly but you never know.
Did you check the tire pressure as I suggested??
