NHTSA Complaint #11719735 — 2024 VOLVO XC60

Tire size: 255/40 R21 The original equipment Pirelli Scorpion Zero All Season VOL PNCS tires (255/40 R21 102V, DOT JXB RW582P) on my 2024 Volvo XC60 CPO developed significant tread chunking and active delamination, discovered at approximately 19,225 miles — less than 40% of the expected tire lifespan. Component: Both front tires are available for inspection upon request. Safety risk: Tread chunks are physically separating from the tire at the tread edge. Active delamination at highway speeds presents a serious blowout risk to myself, passengers, and other drivers. Prior symptoms: No warning lamps illuminated. Initial delamination was noticed earlier by a family member but was not fully examined at that time. Upon closer inspection at 19,225 miles, the extent of the tread chunking and delamination on both front tires was confirmed. The condition appears to have been progressive. Additional note: These tires are original equipment and have never been replaced. The vehicle has been driven exclusively on paved roads under normal conditions with no impacts, curb strikes, or overloading. This is consistent with a known manufacturing defect affecting Pirelli Scorpion Zero tires produced in 2021–2022 installed as OEM equipment on Volvo XC60 vehicles.
