NHTSA complaint #11726183

Owner complaint summary

Component/System Failed: Tire Sidewall (Continental CrossContact LX20 EcoPlus+, Size: 255/55R20 107H). I am reporting a potential safety defect regarding my Continental tires. While my specific mold number (S-421232) is not currently listed in NHTSA Campaign 20T018000, the tires were manufactured in the same week (DOT 0420) and show symptoms consistent with the overcuring defect described in that recall. I have observed unusual marks and [mention what you see: e.g., "cracking," "distortions," or "bubbling"] on the sidewall. These marks appeared without any impact or road hazard. Given that this specific model and production week are already associated with sudden sidewall breakage and carcass failure, I am concerned that the existing recall scope is too narrow and that my tires pose a similar risk of sudden air loss or crash.
