A Tickfaw, Louisiana woman was killed on January 12, 2010 on I-12 in Hammond, Louisiana, when her 2004 Mercury Mountaineer sustained a rear left tire blowout, causing the SUV to roll over several times. The cause of the tire blowout is unknown at this time. It could have been caused by impact damage, excessive wear, or improper installation, inflation or maintenance. Or, many SUV rollover and tire blowout accidents are actually caused by product defects in the SUV and tire. In order to properly investigate the potential product defects in the SUV and tire, the SUV and tire must be preserved for testing.
Common tire defects include a lack of an adequate antidegradant and antioxidant package; inadequate adhesion in the tread belt system; lack of or insufficient belt edge wedges or “gum strips”; a thin inner liner that allows air to leak into the carcass of the tire; and lack of nylon overlays or cap plies. Correction of these common tire defects can prevent catastrophic tread belt separation that lead to tire blowout. Additionally, some SUVs are improperly designed and manufactured with defective handling characteristics; with a roof structure that does not maintain structural integrity in a rollover; with an extremely high center of gravity which results in a propensity to roll over; and with a suspension designed and manufactured in such a manner as to allow the rear end of the vehicle to skate under foreseeable circumstances, resulting in a propensity to overturn. Some SUV manufacturers have even allowed and approved the installation of larger size tires than the vehicle was designed for, thereby increasing the vehicle’s center of gravity and the potential for SUV rollover, and required a substandard inflation pressure for the SUV’s tires.
