An Illinois federal judge upheld a jury verdict for a woman permanently disabled in a motorcycle crash even though her expert witness did not pinpoint the exact cause of the crash. McCloud v. Goodyear Dunlop Tires N. America, Ltd. WL 2323792 (C.D. Ill. June 2, 2008).
Trish McCloud was severely injured in 2002 when the rear tire blew out on her Honda Gold Wing motorcycle. Her expert witness narrowed down the tire defect to three possible manufacturing errors by defendant, Goodyear. Based on his testimony the jury awarded her damages under her Illinois product liability claim.
Goodyear asked for a new trial, in part because it felt that McCloud’s expert had not adequately proved that its product was defective. McCloud’s expert had testified that the blowout was the result of a nylon cord getting embedded in the tire’s innermost layer rather than the layers of rubber, which was where it belonged. This then caused a bubble to form in the sidewall layer of the tire, which eventually burst. Her expert posed three different ways this Illinois product defect could have occurred during the manufacturing process, but did not pinpoint which one specifically was the cause.
In response, Goodyear reasoned that the blowout was the result of the tire being overloaded and under-inflated. It argued that the motorcycle itself was overweight, which would have contributed to this blowout, and further cited inadequate checking of the tire pressure by the owner. Furthermore, the fact that none of its other customers had reported a similar problem was a factor to be considered.
