Well i found the enaswer to what i thought were defects in my tires. See below
Sidewall undulation is an indentation on the sidewall surface of an inflated tire. Undulation is common in almost all radial tires and is most visible on tires with larger sidewalls or tires running at a high inflation pressure.
In a radial tire, the body ply cords run parallel to each other across the tire from bead to bead. With the straight across construction, the joining of the ply material in the sidewall can cause a slight indentation or wavy appearance on the sidewall surface of the tire when it’s inflated.
Tires with sidewall undulation are safe to use on your automobile. The undulation will not affect vehicle performance and will not increase your risk of a blowout or tire failure.
However, if the tire has bulges on the sidewall instead of indentations, the tire has gaps between some of the body ply cords inside the tire. Tires with gaps between the body ply cords may have serious issues and should be taken off the road immediately. Bulges are considered defects and are covered in the manufacturers materials and workmanship warranty.
