NHTSA Complaint #11674101 — 2005 BMW X5

I purchased a used Pirelli Scorpion Strada 255/55R18 109V tire (DOT code 1UN L4W990 4221) for my SUV. When I returned home from the installation, the tire appeared normal. However, the next morning—within 24 hours of installation—I began driving for work when my car suddenly started shaking violently and pulling hard to the right while on the freeway around 3 AM. I was able to safely exit the freeway and pull over. Upon inspection, I discovered that the tire had been shredded by the road—the sidewall had catastrophically failed, and the inner structure had separated. The tire had good tread and showed no signs of damage before the incident. This was a sudden and dangerous failure that placed me at serious risk of losing control of the vehicle. It occurred under normal driving conditions at moderate freeway speed. There were no prior warning signs, dashboard messages, or visible damage. The tire was manufactured in October 2021 at Pirelli’s Rome, Georgia plant. The failure appears consistent with belt separation or internal delamination. The damaged tire has been preserved and is available for inspection. I believe this tire may be part of a defective batch and am reporting this for safety investigation. There are similar complaints online regarding Pirelli tires made in this timeframe.
