Overview

• A loose tire from a westbound 1995 GMC pickup detached shortly before 2:30 a.m. and bounced across lanes and the median before striking the driver’s windshield of an eastbound white Lexus sedan near Garey Avenue in Pomona.
• The impact shattered the windshield and partially collapsed the roof, causing the driver to lose control and crash into a guardrail, where she was pronounced dead at the scene.
• Firefighters and California Highway Patrol officers secured the wreckage and recovered the tire, triggering a SigAlert that closed eastbound lanes until around 4 a.m.
• Witness accounts initially conflicted on whether the tire came from a big rig or a pickup, but CHP logs specifically identified the vehicle as a 1995 GMC pickup truck.
• Authorities are continuing to investigate whether a mechanical failure or insufficient maintenance led to the tire’s separation, and no citations have been issued so far.
