| Tire Sidewall problems |
Cooper discoverer 275-55r20 had a stranger point out a very large bulge on the inner sidewall of my passenger side rear tire. This is the 3rd tire from a set of 4 that has developed the same issue within 3 months. Cooper tires is not wanting to help resolve this issue. They want the tire dissected and returned before doing anything.
On 05/19/2023 driver's side front wheel removed for brake replacement. Noticed large bulge on inner sidewall of cooper discoverer 275-55r20 tire. This was the 2nd tire of a set of 4 that has developed the same issue. Now a third has a bulge. I will submit a 3rd report for it.
Cooper discoverer 275-55r20 developed bulge in inner sidewall. I was unaware of issue until a stranger pointed it out. That was on 03/08/2023. Since then, 2 more tires have developed the same issue!! the last 2 have been looked at by tire installation professionals and determined to be manufacturer defects.
